Indonesia safety, plainly.

Indonesia's real risk is not crime. It is roads, water and geology.

That is the single most useful sentence in this guide, and it is the one the internet gets wrong most often. Bali alone recorded 632 road deaths in the year to mid-2024, and 86 percent of them involved motorcycles. There are roughly 3.9 million scooters on an island of about 4.3 million people. Nothing else in this guide comes close to that number. Not theft, not scams, not violence.

The advisories match. The US State Department has Indonesia at Level 2, exercise increased caution, for natural disasters, unrest and terrorism. The UK Foreign Office has no blanket country advisory at all, only exclusion zones around specific erupting volcanoes. The exception at both is Papua: Central Papua and Highland Papua carry a Level 4, do not travel, because of sporadic localised conflict and because armed separatist groups have kidnapped foreign nationals.

Indonesia is not one place, and this matters more here than almost anywhere. It is around 17,000 islands and 737 living languages [dossier]. Aceh, at the northern tip of Sumatra, is the only province in Indonesia that enforces sharia law. Bali is Hindu, small, and carries most of the country's foreign tourism. Flores, Toraja and much of Papua are Christian. Java holds more than half the population and runs on trains. Nusa Tenggara runs on boats. A safety fact from Bali is a fact about Bali. It tells you almost nothing about Lombok, Sumatra or Sulawesi, and it tells you nothing at all about Aceh.

Two things the internet gets wrong in ways that cost people something.

The first keeps people home. In January 2026 Indonesia's revised criminal code, the KUHP, came into force, including Article 411 on sex outside marriage and Article 412 on unmarried cohabitation. The headlines were catastrophic. The mechanism is narrow: enforcement is complaint-based, and only a legal spouse, parent or child of one of the people involved can file the complaint. Hotels are not required to check marriage certificates, and officials have been told not to run sweeps of guests' marital status. It is a real law with real consequences for Indonesians and, as covered further down, real teeth against same-sex couples. It is not a reason to cancel a trip.

The second gets people hurt. It is the habit of reading Bali's conditions as Indonesia's. Rabies is live in Bali right now. Ferries and fast boats sink. Volcanoes are not scenery, they are monitored hazards with published exclusion zones. Bootleg spirits kill and blind tourists in Bali, Lombok and the Gilis. All of that is boring, avoidable and specific, which is why it gets less attention than a scary law that will not touch you.

Landing after dark is fine in Bali and workable in Jakarta. It is worth planning in Labuan Bajo, Sorong or anywhere small.

Bali, Ngurah Rai (DPS). The only taxis allowed to pick up at the arrivals curb are the airport's own cooperative, Koptax, which works off a fixed zone-based fare counter at both terminals. Since July 2026 Koptax has run a partnership with Blue Bird adding their electric taxis to the airport pool. That counter is the no-thinking-required option at 2am. If you would rather use an app, Grab operates officially through a Grab Lounge inside the arrivals pick-up zone, where staff walk you to your driver, so you never leave the airport perimeter to find a car. Rough fares are IDR 120,000 to 180,000 to Kuta and IDR 200,000 to 320,000 to Ubud, higher when surge is on late at night (verify - changes often).

Jakarta, Soekarno-Hatta (CGK). The airport train runs roughly 05:00 to 23:00, every 30 to 60 minutes, to Batu Ceper, Duri, BNI City and Manggarai, about an hour end to end (verify - changes often). If you land after that it is a car. Book Grab or Gojek in the app rather than accepting an offer in the hall.

The arrivals-hall approach. It is a man, usually indoors, usually before you reach the official rank, offering a taxi or a transfer at a "special price". The script that ends it is short and does not require rudeness: "Tidak, terima kasih", no thank you, and keep walking to the counter. You do not have to explain yourself, and a firm no does not escalate here.

Set up the apps before you fly. Neither Grab nor Gojek requires an Indonesian number, but Gojek is fussier about foreign numbers than Grab, and OTP delivery sometimes fails on prepaid or unusual country codes. Register at home on wifi, not in an arrivals hall at midnight. If Gojek refuses your number, Grab is the fallback.

2am check-in. Small guesthouses, homestays and family-run losmen across Java, Flores, Sumatra and the Gilis do not staff reception overnight. Message the property the day before with your actual arrival time and get a written reply. Hostels and hotels in Bali's south, Canggu, Ubud, Seminyak, and in central Jakarta and Yogyakarta, generally do run 24-hour desks.

Women-only dorms are a real option here, not a listing-site fiction, but they are concentrated.

Bali has genuinely female-only properties, not just a female floor in a mixed hostel. Arya Wellness in Ubud is women-only as a whole hostel. Canggu and Kuta have hostels with dedicated female dorms alongside mixed ones. Outside Bali the picture thins fast: filtering for female dorms on the booking platforms returns very little in Yogyakarta, Flores, Sumatra or Sulawesi. Assume mixed dorms or a private room east and west of Bali.

The category that leaves you alone in a room for a week is the villa. Indonesia sells villas hard, and a private villa down a lane in Canggu or Ubud is a beautiful way to speak to nobody for six days. Hostels, dive shops and multi-day boat trips are where solo travellers actually meet each other, and the Bali to Komodo sailing boats in particular are a forced-social format that works if you want company.

On neighbourhoods, this guide is being honest rather than confident. Well-sourced, current, neighbourhood-by-neighbourhood "which streets change character after dark" data for Indonesian cities does not exist in the way it does for Bangkok or Delhi. What is documented: Seminyak and Canggu are described as well-patrolled and traveller-oriented [4stogo, nightlife sources], Yogyakarta is a student city with a young, walkable centre [solo-travel accounts], and Jakarta's harassment reports skew towards traditional markets and outer neighbourhoods rather than the central business district or the mall belt.

One gap worth naming rather than papering over: we could not find a current, specific list of areas that turn after dark in Denpasar, Jakarta, Surabaya, Medan or Makassar. Nothing was precise enough to name a street and an hour. Padding this with "avoid poorly lit areas" would be worse than leaving it open, so it stays open. Ask your accommodation on arrival, they will know the block.

Commercial friction here is mostly about money changing hands at the wrong rate, not about anyone taking anything from you by force.

The scooter is the risk. Everything else in this section is logistics.

If you do not already ride a motorbike at home, Indonesia is not where you learn. Bali's road death figures are in the big picture section and they are the whole argument. Traffic discipline is poor, the Foreign Office notes a large increase in fatal moped and motorbike accidents in Bali specifically, and warns that foreigners involved in even minor traffic incidents can be vulnerable to extortion.

If you do ride, get the paperwork right before you leave home, because it is what your insurance turns on.

• 01You need your home motorcycle licence plus an International Driving Permit with motorcycle entitlement, category A. A car-only licence is not enough, and a car-only IDP is not enough.
• 02The temporary 30-day licence that used to be available at Denpasar police station no longer is.
• 03Police checkpoints targeting foreign riders have increased sharply in Canggu, Ubud and Kuta in Lombok. Expect to be asked for the vehicle registration, the STNK, plus your licence and IDP.
• 04Missing documents run roughly IDR 300,000 to 500,000 each. No helmet, riding shirtless, or a modified exhaust can reach IDR 1,000,000 (verify - changes often).
• 05Riding without the correct entitlement will almost certainly void your travel insurance in a crash, which is the part that turns a broken leg into a five-figure bill.

On police stops, honestly. The official process is a blue ticket, the slip biru, which you pay at a BRI bank within about 14 days before collecting your documents from the police office. What often happens instead is an on-the-spot cash settlement. Transparency International rates the Indonesian police among the country's most corrupt institutions, and 30.6 percent of surveyed Indonesians report having paid police bribes, traffic fines included. You are allowed to ask for the blue ticket. Say "minta slip biru" and be prepared for it to take longer. Whether that is worth your afternoon is your call, and it is a genuine call, not a moral one.

The apps. Gojek and Grab are what locals use, for cars and for motorbike taxis both. InDrive and Maxim also operate. Gojek doubles as food delivery and payments, so set it up on day one. Blue Bird is the reliable metered taxi brand and the Foreign Office names it alongside Silverbird and Express as registered operators worth using.

Front seat or back seat. In a GrabCar or GoCar the back seat is the default and nobody reads anything into it. On a motorbike taxi you ride pillion behind the driver, who will almost always be a man, and this is completely unremarkable across Indonesia. It is not a signal and it is not read as one. What is worth knowing is the other side of it: reporting of harassment through the ride-hailing platforms has been documented as inadequate, with complaints handled poorly by both companies. The practical consequence is to keep the ride inside the app, where the driver's identity is logged, rather than agreeing a cash price with someone who approached you on the street. Bali's March 2026 assault cases included one attributed to a motorbike taxi driver picked up outside the apps.

Women-only carriages. They exist in Jakarta and only in Jakarta. The KRL Commuter Line has had women-only carriages since 1 October 2012, positioned at the front and rear of each train, with male passengers prohibited. TransJakarta has had women-only areas on its buses since December 2011. Worth knowing: after an April 2026 collision at Bekasi Timur station in which 16 women died because the striking train hit the rear carriage, the women's carriage, the Women's Empowerment Ministry proposed relocating them to the middle of the formation. Check where they are when you board. Long-distance KAI trains across Java have assigned seats in executive class and no women-only carriage.

Boats, which deserve more caution than they get. The Foreign Office puts it plainly: sea conditions change rapidly, safety standards vary between providers, and vessels can be crowded, overloaded and poorly maintained. Two recent cases make it concrete. The roll-on ferry KMP Tunu Pratama Jaya sank about 30 minutes into the Banyuwangi to Bali crossing on 2 July 2025, killing at least 19 with 16 more missing; the national transport safety committee's preliminary finding was that the crew had not closed the engine room door before sailing. In August 2025 the Dolphin II fast boat returning from Nusa Penida capsized off Sanur with 80 people aboard and two passengers died. Fast boats are lightly regulated, with no single authority enforcing vessel inspection or crew training.

• 01Book a named operator rather than the cheapest counter ticket. BlueWater Express, Eka Jaya, Gili Getaway and Gili Gili are the ones consistently named as running to a higher standard on the Bali to Gili and Lombok routes.
• 02Find the life jackets before you sit down, not after something happens.
• 03If the sea looks wrong and the boat is going anyway, do not go. Crossings in the October to March wet season are choppier and cancellations are common.
• 04Do not travel by small boat after dark.

Long distance by land. Java has the rail network, and executive class with assigned seats is the civilised way across it. Overnight buses cover the rest, with Rosalia Indah, Sinar Jaya, Lorena, Pahala Kencana and Juragan 99 the operators named as reliable on long Java routes. Two practical habits on night buses: keep valuables on your body rather than in the overhead rack, and photograph your bus and its plate at every rest stop, because buses move in the car park while you are inside.

Here is the honest frequency, which is not the same as reassurance.

The dominant form of attention in Indonesia is not threat, it is interest. In Java and Sumatra outside the tourist strips, being asked for photographs is routine and frequent, several times a day at somewhere like Borobudur or Prambanan. School groups are sent by their teachers to practise English on foreigners, and once one person asks for a photo others who were too shy will follow. This is not harassment and it is not aimed at you as a woman, it happens to foreign men too. It is also relentless when you are tired. You are allowed to say no. A smile and "maaf, tidak" ends it without incident.

The same applies to personal questions. Where are you from, how old are you, what is your religion, are you married, where is your husband. This sequence is standard opening small talk in Indonesia, offered to break the ice or practise English, and there is no equivalent concept of a question being too personal. It is not usually a proposition. If you want a short answer that closes the topic, "yes, married, he's at the hotel" works and nobody will check. If you do not want to say that, "not married" is a perfectly ordinary answer that will produce more questions rather than fewer.

Catcalling and staring do happen. First-hand accounts put it more often in traditional markets and outer neighbourhoods than in city centres or upscale areas, and one traveller reports ongoing catcalls specifically when entering male-dominated warungs. A first-hand account from early 2025 covering Bali, Lombok, Gili Air and Java reported minimal harassment across the whole trip, with one drunk man in a town square in Malang that she walked away from. That is a realistic normal Tuesday: nothing, some staring, someone wanting a photo, occasionally a comment.

What de-escalates here is firmness without heat. A clear, unembarrassed "tidak, terima kasih" and continuing to walk is the thing that works. Public anger is read badly in Indonesian social norms and tends to make the situation stickier rather than ending it. This is not a country where you need to escalate to be taken seriously.

Now the part that is not reassuring. The Foreign Office states that reported cases of rape and sexual assault are high in Bali and Lombok, and advises being alert at night and avoiding poorly lit areas. In one week in March 2026 three foreign tourists reported sexual assaults in Bali, in Pecatu, Seminyak and Canggu. Police characterisation of those cases, describing victims as having been "given an opportunity", drew public criticism for shifting responsibility. Separately, police pursued a motorbike taxi driver over the assault of a Chinese tourist on New Year's Eve. The action attached to this is narrow and specific: keep rides inside the apps where the driver is logged, do not accept a lift arranged by conversation, and treat the walk home after drinking as the part of the night that needs a plan. It is not a reason to stay in.

Walking alone at night. In Bali's tourist south, in central Jakarta, and in Yogyakarta's centre, local women are out on foot in the evening and you will not stand out. In conservative regions, in small towns and in rural areas across Sumatra, Java and Nusa Tenggara, streets empty earlier and a woman walking alone after dark is unusual and will be noticed. That is a visibility problem more than a danger problem, but it is real and it is worth knowing before you plan a 9pm walk in Bukittinggi.

This is logistics. Heat, temple doors, and one province with a different legal system.

What local women wear. In Bali's tourist south and in Jakarta's malls and offices, western clothing is entirely unremarkable. Across most of the rest of the country, including Java outside the tourist sites, most of Sumatra, Lombok and much of Sulawesi, the everyday norm for local women is covered shoulders and knee-length or longer, frequently with a headscarf. Christian and Chinese-Indonesian women dress more casually than the Muslim majority, so you will see variation within the same street.

Balinese temples, precisely. You need a sarong wrapped from waist to ankle and a sash tied at the waist, plus shoulders covered. Most temples that charge entry lend or rent both. Shoes come off at the inner areas. There is one rule that is easy to walk into unknowingly: menstruating women are asked not to enter, and at many temples are asked to remain in the outer courtyard rather than the inner sanctum. The same applies to open wounds, to late pregnancy, and to the first weeks after giving birth. Nobody checks and nobody asks. It is a Balinese Hindu religious rule kept on trust, and the practical consequence is that if you have planned your one Besakih or Tirta Empul day and your period arrives, the outer courtyard is the visit you get.

Mosques. A headscarf is required to enter, along with covered arms and legs. Large mosques usually lend a robe and scarf at the door.

Aceh, which is genuinely different. Aceh is the only Indonesian province enforcing sharia law, under the Qanun Jinayat, and it covers alcohol, gambling, khalwat which is being alone with an unrelated person of the opposite sex, ikhtilath, extramarital sex and same-sex acts, with caning, fines measured in grams of gold, and imprisonment as penalties.

The question of who it applies to has a genuinely conflicting answer, and you should have both halves.

• 01The UK Foreign Office states flatly that the laws apply to both Muslims and non-Muslims.
• 02The Aceh provincial office in Jakarta and the provincial religious affairs office have stated that foreign citizens, Muslim and non-Muslim, are exempt, and that caning applies exclusively to Muslims, with non-Muslim Indonesians facing administrative sanctions or fines instead.
• 03The qanun's own text applies to non-Muslims where an offence is not covered by the national criminal code, or where it was committed jointly with a Muslim and the non-Muslim chooses sharia jurisdiction.
• 04There is at least one documented case of a non-Muslim being caned: a Christian Indonesian woman received 28 strokes in April 2016 for selling alcohol.
• 05Caning continues and is not symbolic. In May 2026 the Southeast Aceh prosecutor's office caned 15 people with more than 200 strokes between them.

What that means practically for a woman travelling alone in Aceh. The Sharia Police in practice grant an exception on headscarves to non-Muslim foreigners who can show identification, and foreign women without headscarves are a visible and tolerated presence in Banda Aceh. The working standard is long sleeves, and loose trousers or a skirt below the knee. Tight jeans read as non-compliant even though they are technically trousers. No bikinis on public beaches; check with your hotel about its pool. Alcohol is not sold openly anywhere in Banda Aceh, and consumption carries a caning penalty; Pulau Weh, where most visitors go, has restaurants with informal approval to serve non-Muslim tourists. Avoid public affection entirely.

The one to take most seriously is khalwat. Being alone in a private space with an unrelated man, including a guide or a driver, is the offence category most likely to catch a foreigner out, and it does not require anything to have happened. Keep travel arrangements in Aceh in public or in groups.

Does covering up reduce attention? Honestly: in conservative regions, yes, measurably. Travellers who dress to the local norm report noticeably fewer comments in Java, Sumatra and Lombok. In Bali's tourist south it makes no measurable difference, because the baseline is a beach economy where nobody is looking. That is a practical observation about where you are, not a statement about what anyone deserves.

Eating alone is fine and increasingly ordinary. In Indonesian cities, people eating alone at warungs and restaurants is a common sight and a documented shift, driven by work schedules and commutes. What you may get is a comment rather than a stare, because eating is social here and someone may ask, half-curious and half-concerned, whether you are eating alone. It is warmth, not judgement. The one place it can turn is a male-dominated warung, where a lone woman entering has drawn catcalls. You will be able to see which ones those are from the doorway.

Formats built for one. Nasi campur and nasi goreng are single plates by default everywhere. Warungs serve individual portions from a display case, you point at what you want. Angkringan carts in Yogyakarta serve nasi kucing, deliberately tiny portions you stack up. Padang restaurants use the hidang system, where a dozen or more small dishes land on your table and you pay only for what you touch, and solo diners are typically brought a reduced spread rather than the full array. That last one is genuinely worth knowing so you do not panic at the sight of fourteen bowls.

Sitting at a bar alone. In Bali's tourist areas, Jakarta's bar districts and the Gilis this is unremarkable and reads as nothing. Outside those, standalone bars barely exist as a category, so the question mostly does not arise.

Water and street food, the unglamorous rules. Do not drink the tap water anywhere in Indonesia, including Bali. Brushing teeth with it is fine. Bottled water is everywhere and cheap, and refill points are common in Bali and the backpacker corridors. On food, the working rule is turnover: a stall with a queue of locals is fresher than a quiet tourist restaurant, because the stock has to move. Ice in established restaurants and cafes is commercially produced and fine; irregular hand-cut ice in a remote warung is the one to skip.

Alcohol. Legal and normal everywhere except Aceh, where it is illegal for everyone and carries a caning penalty. The serious risk with alcohol here is methanol, and it is covered in the nightlife section because that is where it kills people.

Ramadan. During the fasting month, do not eat, drink, smoke or chew gum in public during daylight, including in a car, and avoid loud music and dancing. This matters in conservative regions and much less in Bali. Ramadan moves each year against the Gregorian calendar, so check the dates for your trip (verify - changes often).

The section most guides skip, so here is the specific version.

Period products. Pads, pembalut, are everywhere: Indomaret, Alfamart, every apotek, every supermarket, and cheap. Tampons are a different story. Most Indonesian women do not use them, partly because of a persistent belief that they affect virginity, so they are not a mainstream product and shops that do carry them often keep them somewhere unobvious. Where they turn up: the Guardian and Century pharmacy chains, large supermarkets such as Hypermart, Grand Lucky and Carrefour, and Japanese supermarkets, in Jakarta, Bali's south and Ubud, at roughly IDR 30,000 to 50,000 for a box of eight (verify - changes often). Watsons Indonesia lists a tampon category online. Outside those cities, in Flores, Sumba, Raja Ampat, rural Sumatra and most of Sulawesi, treat tampons as unavailable. Menstrual cups and period underwear are not reliably stocked anywhere in the country. Bring what you use. If you are going east, bring the whole trip's worth.

Pharmacies. They are called apotek and are marked with a green cross. Indonesian packaging uses a colour code that tells you the rule at a glance: a green circle is freely available over the counter, a blue circle is limited over the counter, a red circle with a K means prescription-only, and a red circle with an N means narcotic.

What is genuinely over the counter: paracetamol and ibuprofen, antihistamines, antacids, cough and cold remedies, simple eye drops, topical creams.

What is legally prescription-only: antibiotics, antifungals, most hormonal medication, controlled painkillers, most inhalers.

What actually happens is different from what the law says, and you should know both. A study by the Indonesian Pharmacists Association found 79.5 percent of pharmacies dispensing antibiotics without a prescription, 82.3 percent in urban areas. Reports from Ubud and Jakarta describe the same in practice. So for a UTI, the antibiotics used are cefixime, ciprofloxacin and levofloxacin, legally prescription-only, and commonly sold over the counter anyway. Do not plan on that. Bring a course of whatever your doctor recommends for UTIs if you are prone to them, and treat over-the-counter access as a fallback, not a plan. Thrush treatment is antifungal and therefore prescription-only on paper, with the same gap in practice. Bring it.

Contraception. The pill can be bought at most apotek without a prescription in practice. There is no law barring a doctor from prescribing to an unmarried woman, but the state does not explicitly endorse it, so most government-funded clinics will not write a prescription without seeing a marriage certificate, and national family planning services have historically not served unmarried couples. Government Regulation 28 of 2024 regulates contraceptive provision including to adolescents, and remains restrictive in its conditions. Condoms are available everywhere, including convenience stores.

Emergency contraception, specifically. Postinor-2, levonorgestrel, is the brand you will find. It is legally prescription-only in Indonesia, and that requirement is not consistently enforced. Pharmacists in Jakarta and Ubud are reported to sell it without a prescription routinely; travellers have reported difficulty obtaining it in Lombok even with a prescription. A box has been reported around IDR 44,000, though that figure is several years old (verify - changes often). The practical read: buy it in Jakarta, Denpasar or Ubud if you need it, not in a small town, and if the timing of your trip makes it matter, carry your own, because a refusal in Labuan Bajo or Bukit Lawang costs you the window. Postinor-2 works up to 120 hours after, and sooner is better.

A findable female doctor. In Bali, BaliMéd Hospital in Denpasar runs a dedicated obstetrics and gynaecology clinic, and BIMC, Siloam and Bali Royal are all used to foreign patients. Aggregator listings name several English-speaking gynaecologists in Bali including female practitioners, with examination plus ultrasound from about IDR 400,000 (verify - changes often). In Jakarta, RS Pondok Indah runs an obstetrics and gynaecology clinic with online booking, and Abdi Waluyo Hospital on Jalan HOS Cokroaminoto in Central Jakarta is another. PKBI is the Indonesian equivalent of Planned Parenthood and provides sexual health services. Individual doctors move between hospitals, so book by institution and ask for a female doctor when you call rather than chasing a name from a blog.

The hospital worth going to, named, with the cost. In Bali:

• 01BIMC Hospital, Kuta and Nusa Dua. Built for international patients, best English across all staff, widest direct billing with international insurers. Consultation IDR 800,000 to 1,500,000, emergency assessment IDR 2,000,000 to 5,000,000. Emergency lines +62 361 761263 Kuta, +62 361 3000911 Nusa Dua (verify - changes often).
• 02Siloam Hospitals Denpasar. Good English among doctors, more variable among nursing staff, moderate pricing. Consultation IDR 400,000 to 800,000. Emergency +62 361 779900.
• 03Kasih Ibu, Denpasar. Consultation IDR 250,000 to 500,000, emergency +62 361 223036.
• 04RSUP Prof. Ngoerah, formerly Sanglah, Denpasar. The public reference hospital, cheapest at IDR 100,000 to 300,000, variable English, and the only place on the island with neurosurgery, a burns unit and a hyperbaric chamber. Emergency +62 361 227911.

Medical evacuation to Singapore or Bangkok runs USD 20,000 to 100,000 and up without insurance. Insurance with medevac cover is the single most important thing you buy for this country, and it is the reason the scooter licence paperwork matters.

Emergency numbers. 112 is the universal emergency line. 110 is police, 118 and 119 are ambulance, 113 is fire, 115 is BASARNAS search and rescue. English is not guaranteed on any of them. In Bali's tourist south, staff at hospitals and police stations in the main areas will generally understand English. Outside that, assume you will need the hotel, a driver or a stranger to translate, and Google Translate as the fallback. Bali's tourist police are reachable on +62 361 224 111, with Kuta station on +62 361 784 5988 and the airport post on +62 361 935 102. A number 155 is widely quoted on Bali travel sites as a tourist police hotline; we could not verify it against any official Indonesian source, so use the direct numbers above instead.

Rabies, which is live and current. Bali declared rabies red zones in tourist areas in 2025, and provincial authorities have renewed warnings to visitors at monkey parks and wildlife attractions [dossier]. A monkey scratch carries the same risk as a dog bite, because macaques lick their paws. Uluwatu's monkeys steal glasses and hats to trade for food, and Ubud's Monkey Forest reports no rabies cases in its own troop since 1960, but neither of those changes what you do if skin is broken.

• 01Wash the wound with soap under running water for a full 15 minutes. This is not optional and it measurably reduces viral load.
• 02Get post-exposure prophylaxis the same day. The course is 4 to 5 doses over 2 to 4 weeks.
• 03For deep or bleeding wounds you also need rabies immunoglobulin, which has been in short supply in Bali and which many public puskesmas clinics do not stock.
• 04Budget for it. A full course has been reported at up to USD 2,000, which is another argument for insurance (verify - changes often).
• 05Rabies is effectively always fatal once symptoms start. There is no version of this where you wait and see.

Mosquitoes. Dengue circulates nationwide and the mosquitoes bite during the day. Indonesia recorded over 257,000 cases and more than 1,400 deaths in 2024. There is no prophylaxis, so repellent during daylight is the whole strategy. Malaria is a separate map: the CDC classifies Bali, Ubud and the Gili Islands as no risk, while Papua including Raja Ampat carries year-round transmission with drug-resistant P. falciparum, and parts of Sumba, Flores and rural Sumatra have active cases. If you are going east, talk to a travel clinic about prophylaxis before you fly. Chloroquine does not work here.

Going out alone is normal in exactly three places and notable everywhere else.

Bali's south, meaning Canggu, Seminyak, Kuta and Uluwatu, plus the Gili Islands and central Jakarta's bar districts, have enough foreign and local women out on their own that you are not a subject of interest. Outside those, standalone bars are largely not a social category, and a woman drinking alone in a small town in Java or Sumatra will be noticed and, in the more conservative regions, disapproved of.

Methanol is the thing that actually kills tourists here, and it does not get enough attention. Bootleg spirits, sold as arak or oplosan and distilled from palm sap, rice or sugarcane, are adulterated with methanol. Indonesia has recorded the highest number of methanol poisoning incidents in the world over the past two decades, and Médecins Sans Frontières has tracked hundreds of suspected cases. Deaths and permanent blindness among foreign visitors are documented in Bali, Lombok, the Gili Islands and Sumatra. The UK expanded its tainted-alcohol advisory to cover this in October 2025. Roughly the volume of a single shot can be fatal within 12 to 48 hours. The Foreign Office is blunt that you cannot detect methanol by taste or smell.

• 01Drink beer, or spirits poured from a sealed, branded bottle you can see.
• 02Refuse free-pour cocktails at cheap bars, buckets, and anything labelled a free welcome drink.
• 03Refuse arak entirely. There is no reliable way to tell a safe batch from a bad one.
• 04Symptom onset is delayed. Blurred or dimming vision, severe headache, breathlessness or vomiting hours after drinking is a hospital emergency, not a hangover. Go to BIMC or Siloam immediately, do not sleep it off.

Drink spiking. The Foreign Office states there have been reports of drink spiking linked to sexual assault in Bali, Lombok and the Gili Islands specifically. Watch the drink being made, keep it in your hand, and abandon anything you left on a table. This is the same precaution as everywhere, and the reason it is named here is that the Foreign Office named the three places.

Getting home at 2am. In Bali's south and central Jakarta, Grab and Gojek run through the night, and the walk to a legal pickup point outside a no-app zone is the only complication. On Gili Trawangan there is no motorised transport at all, so getting home is a walk or a bicycle in the dark, and police presence on the island is minimal, a handful of officers around the jetty area. Stick to the main beach path rather than the inland lanes, and leave with people you arrived with.

Magic mushrooms are sold openly on Gili Trawangan, in beachfront shakes and at named cafes, and they are illegal. Openness is not legality, and Indonesian narcotics law does not soften for tourists. That is covered in the next section and it is not a small thing.

Homosexuality is not criminalised at national level. That sentence is true and it is not the whole picture, so here is the rest.

The revised criminal code in force since 2 January 2026 criminalises sex outside marriage under Article 411 and unmarried cohabitation under Article 412. Because Indonesia does not recognise same-sex marriage, those articles apply to every same-sex couple in the country by construction. Enforcement is complaint-based and the complainant must be a spouse, parent or child, which is a genuine limit and not nothing.

Aceh is a separate legal system and the risk there is concrete. Same-sex acts are criminalised under the Qanun Jinayat, and the punishment is public caning. Two men were caned 77 strokes each in Banda Aceh after being sentenced for having sex together; two more, aged 20 and 21, were sentenced to caning in August 2025 for kissing after police broke into a public toilet. Police have raided beauty salons in Aceh and arrested trans employees for violating provincial religious law. Do not test this.

Elsewhere, the pattern is raids on private gatherings. 56 men were arrested at a private gathering in Jakarta, with three charged under anti-pornography law and facing up to 15 years. In June 2025, 75 people were arrested at a private villa near Jakarta. The Foreign Office notes reports of police arresting people at LGBT+ events, and that pornography and prostitution laws have been applied in discriminatory ways, and advises caution and discretion in public.

Practically: Bali's tourist areas and parts of Jakarta function quietly and without incident for visitors, and a same-sex couple sharing a room in Seminyak is not a story anyone is telling. Public affection is conservative across Indonesia for everyone, straight couples included, so discretion in public is the general norm rather than a special instruction. The two hard lines are Aceh, and organised gatherings advertised in ways that police can find.

This is the category that actually generates the incidents, and every item has a source you can check on the day.

Volcanoes. Indonesia has more active volcanoes than any country on earth. The official monitoring body is PVMBG and the live source is MAGMA Indonesia at magma.esdm.go.id, which the Foreign Office points travellers to directly. Alert levels run 1 to 4: Normal, Waspada, Siaga, Awas. As of July 2026 Semeru in East Java sat at Level 3, along with Lewotobi Laki-laki, Merapi and Krakatau, with Marapi, Dukono, Ibu and Lewotolok at Level 2 (verify - changes often). The Foreign Office advises against all travel inside published exclusion zones, which at its most recent update covered Lewotobi Laki-Laki at 7km, Sinabung at 5km, Marapi at 3km, Semeru at 5km plus 500m from riverbanks, Ruang at 7km and Ibu at 7km (verify - changes often). Check MAGMA the week you go and again the morning you go. A tour operator's willingness to run a trip is not a safety assessment.

Trekking, and the Rinjani case. In June 2025 Juliana Marins, a Brazilian solo traveller, was left alone to rest on the Mount Rinjani trail on Lombok, slipped, and fell around 300 metres below the path. Drone footage confirmed she was alive and conscious after the fall. Terrain, fog and cold kept rescuers from reaching her until 24 June, and she had died of multiple fractures and haemorrhage. The case exposed that Rinjani treks carried no mandatory safety equipment and that some guides were working without food, thermal kit or footwear adequate to the mountain. The lessons are actionable: book an operator that carries radio or satellite communication, warm layers and a stated evacuation plan, ask what happens if someone cannot continue, and do not accept being left alone on a trail, ever, for any reason. Rinjani was closed pending evaluation after the incident, so confirm status before you book (verify - changes often).

Water. Nusa Penida's Kelingking Beach and Diamond Beach have standing no-swim rules and produce injuries and deaths every year, both from people entering the water and from people attempting the cliff descents unprepared. A French tourist was swept off Kelingking in October 2025 having ignored the warnings, and a local guide drowned there in a separate incident. On Bali's west coast, Kuta, Legian and Canggu have real rip currents and a Balawista lifeguard service that flies flags. Swim between the flags and nowhere else. If you are caught in a rip, do not swim against it, swim parallel to the beach until you are out of it.

Diving. Komodo and Nusa Penida both sit in the Indonesian Throughflow, which pushes enormous volumes of water through narrow channels. Currents change direction and strength quickly, and down-currents at wall and drop-off sites are the specific hazard, not the horizontal drift. Advanced certification plus actual drift experience is what these sites want, and the safety standard for a good operator is a maximum of four divers per guide, with surface marker buoys and emergency oxygen on the boat. Ask about both before you pay.

Chamber coverage is thin and worth knowing before you plan a dive-heavy trip. There is a hyperbaric chamber at RSUP Prof. Ngoerah in Denpasar, one at the Kasih Ibu Saba facility in Gianyar, Bali, one at Siloam in Labuan Bajo serving Komodo, opened in 2018 with an eight-person capacity, and three in Manado, North Sulawesi. We could not confirm a chamber at Sorong or Waisai serving Raja Ampat. Assume a decompression injury there means an evacuation flight, and dive conservatively.

Earthquakes and tsunami. Earthquakes are frequent nationwide. BMKG runs the national tsunami warning system, InaTEWS. The rule that matters on a coast: if shaking lasts around 20 seconds or more, do not wait for a phone alert or an official siren. Move inland or to 20 metres of elevation immediately. A tsunami can arrive within minutes of a nearshore quake. Do not go down to look at water receding from the beach; if the water pulls back the wave is already on its way.

Weather. Rainy season runs roughly October to March with flash flooding, and the roads to Jakarta's airport are particularly vulnerable. Wildfire haze across Sumatra and Kalimantan is worst in the dry season, April to September, and degrades air quality across the region.

A short list. Shorter than the internet's, and every item is here because it is real.

• 01Drugs. This is the one that ruins lives. Law No. 35 of 2009 governs narcotics. Possession of even a small quantity of a Class I drug carries 4 to 12 years and very large fines. Above 1kg of plant material or 5g of non-plant material, the range is life imprisonment or the death penalty, and Indonesian law does not distinguish between a small-time dealer and a trafficker for Class I offences. All forms of cannabis are illegal, including medicinal, CBD oil, THC and edibles. Police may take urine or blood tests where they suspect use, and a positive result triggers arrest. The mushrooms sold openly on Gili Trawangan are inside this law. There is no tourist exemption and there is no version of this worth the risk.
• 02Riding a scooter without the right licence, or without ever having ridden one. The whole argument is in the transport section. It is the leading cause of serious injury and death among foreign visitors and it voids your insurance.
• 03Central Papua and Highland Papua. US Level 4, do not travel. Sporadic localised armed conflict, and armed separatist groups have kidnapped foreign nationals. Raja Ampat, in Southwest Papua, is not covered by this and is a different situation.
• 04Volcano exclusion zones. Published, current, and ignored by people who booked a tour. Check MAGMA.
• 05Swimming where there is a no-swim rule. Kelingking and Diamond Beach on Nusa Penida in particular.
• 06Bootleg spirits. See nightlife. This one has killed and blinded tourists.
• 07Small boats after dark, in bad weather, or with the cheapest operator. The Foreign Office's own description of the sector is crowded, overloaded and poorly maintained.
• 08Anything sold to you as an experience that is somebody's exploitation. Child sex trafficking in Bali is documented and persistent, and it operates through the tourism economy. It is not an underworld thing happening somewhere else.
• 09Terrorism, kept in proportion. The Foreign Office assesses that terrorists are likely to try to carry out attacks in Indonesia, with beach resorts, hotels, malls, places of worship, transport hubs and embassies as potential targets, and flags heightened risk around Christmas, New Year, Nyepi, Ramadan, elections and Independence Day on 17 August. This has not been the shape of a visitor's trip for many years and it does not warrant changing plans. It warrants knowing the dates.

Two different answers, depending on what happened.

For a theft or a loss, the police are worth going to, and the reason is paperwork. You want the surat kehilangan, the police loss report, which your insurer will require and which the embassy will want if a passport is gone. Go to the nearest police station, the polsek, for the area where it happened. Bring a passport copy. It is free, they will take a statement and have you sign it, and it usually takes an hour or two. Most travel policies require the report within 24 hours of the incident, so this is a same-day errand, not a tomorrow one. If language is a problem, take someone from your accommodation or use a translation app. The UK Foreign Office publishes a specific guidance page on reporting a crime or police misconduct in Indonesia which is worth having open.

For harassment or assault, be realistic about what you are walking into. Indonesian police are rated among the country's most corrupt institutions by Transparency International, with 30.6 percent of surveyed Indonesians reporting having paid bribes. Bali police were investigated in one case for extorting a Colombian tourist who came in to report a lost phone. When three foreign tourists reported sexual assaults in Bali in a single week in March 2026, police public characterisation of the cases drew criticism for framing them around what the victims had allowed to happen. That is not a reason not to report. It is a reason to bring someone with you, ideally from your accommodation or a consulate, to write down names and times, and to expect the process to be slow and unsatisfying rather than swift.

Bali tourist police are your better first call for anything visitor-related: hotline +62 361 224 111, Kuta station +62 361 784 5988, airport post +62 361 935 102. They are described as more used to foreigners and better in English than the general force.

SAPA 129 is the national line for violence against women and children, run by the Ministry of Women's Empowerment and Child Protection. Call 129, or WhatsApp 0811 1129 129. What it actually provides, beyond taking a report: psychological counselling, a health examination, medical documentation of injuries, and someone to accompany you when dealing with police and hospitals. That accompaniment is the part worth knowing about, because it addresses exactly the problem above. We could not confirm whether English-language support is available on the line, so assume you may need a translator.

Embassy. For Indian nationals: the Embassy of India in Jakarta is at Gama Tower, 28th floor, Jl. HR Rasuna Said Kav. C22, Kuningan, South Jakarta, switchboard +62 21 2522299, with an emergency consular number of +62 815 7513 1310 for genuine emergencies rather than routine enquiries. There is a Consulate General in Bali and another in Medan. For a lost or stolen passport the consulate issues an Emergency Certificate, a one-way travel document for return to India. Neither mission publishes a turnaround time for an emergency travel document, so ask when you call.

Note that the Foreign Office reminds visitors you are required to carry your passport or stay permit at all times in Indonesia. Carry a photocopy plus a photo on your phone, and leave the original in the room safe unless you are travelling between provinces.

If you were going next month, this is what would actually get said.

Pick one corridor and do it properly. Java to Bali, or Bali east to Komodo, or North Sumatra. The country is the width of Europe and the temptation to add a fourth island is where trips fall apart. You will not run out of Indonesia.

Do not rent the scooter unless you already ride one at home. This is the whole ballgame. If you do ride, get the International Driving Permit with the motorcycle category before you fly, because without it your insurance will not pay and the roads here are the thing that hurts people. If you are not riding, Gojek and Grab cover everything, they cost almost nothing, and walking 200 metres to a legal pickup point is a fair price for never negotiating a fare.

Set both apps up at home. Buy the eSIM before you land. Both of those remove a bad twenty minutes at midnight in an arrivals hall.

Bring your own tampons, and bring the whole trip's worth if you are going anywhere east of Bali. Bring UTI and thrush treatment rather than assuming a pharmacy in Labuan Bajo will sort it. If emergency contraception matters to your trip, buy it in Denpasar or Jakarta where it is easy, not in a small town where you will be told no.

Wash any bite or scratch, dog or monkey, with soap under running water for fifteen minutes, and then go to a clinic the same day. Not tomorrow. Rabies is the one thing on this list where waiting is fatal, and it is genuinely live in Bali right now.

Beer or a sealed bottle. Never arak, never a bucket, never a free welcome cocktail. Methanol is the risk that actually kills visitors here and you cannot taste it.

Check magma.esdm.go.id before any volcano day, and take the exclusion zones as literal. Do not swim at Kelingking. Do not let a trekking guide leave you alone on a mountain.

And the thing that underlies all of it: Aceh is not Bali, Bali is not Java, and Java is not Papua. People arrive with one mental model of Indonesia and get caught out by the second island. Read the region you are actually going to, not the country. Everything else in this guide is downstream of that.
