Visas & entry
Most holders of major passports (including US, UK, EU, Australian and many Asian passports) can generally enter on a 30-day Visa on Arrival/e-VOA, usually extendable once for another 30 days; ASEAN nationals often have visa-free access for short stays. Rules, eligible nationalities, passport-validity requirements and the e-VOA process change, so verify directly with Indonesian Immigration before booking; Bali also charges a separate Rp150,000 foreign-tourist levy, paid once per trip through the official Love Bali system.
Getting in
- Jakarta — Soekarno-Hatta International Airport: The main long-haul gateway and Indonesia's broadest domestic-flight hub. Best for starting a Java rail itinerary or connecting onward to Sumatra, Sulawesi, Kalimantan and eastern Indonesia; allow time for Jakarta traffic and airport transfers.
- Bali — Ngurah Rai International Airport, Denpasar: The easiest international arrival for Bali and the Lesser Sundas. It is the practical gateway for Lombok, Labuan Bajo/Komodo and many domestic connections, though it is not a shortcut to the rest of the archipelago.
- Medan — Kualanamu International Airport: A useful secondary international and domestic gateway for North Sumatra: Bukit Lawang, Lake Toba and onward connections. Choose it rather than routing through Jakarta if Sumatra is the point of the trip.
- Surabaya — Juanda International Airport: East Java's major gateway, useful for Bromo, Ijen and domestic links. It can save a backtrack through Jakarta when traveling east across Java or continuing to Bali.
- Makassar — Sultan Hasanuddin International Airport: The key hub for Sulawesi and many eastern-island domestic routes. Use it for South Sulawesi/Tana Toraja and connections toward Manado, Maluku and Papua rather than treating it as a minor stop.
Getting around
Flights are the realistic way to cross island groups; schedule buffer nights before international departures, especially after boats or remote domestic-air segments. Java is the major exception: its intercity trains make Jakarta–Yogyakarta–Surabaya/Malang far easier and more comfortable than driving. Cars with drivers work well for local touring but roads are slow; Bali traffic, Sumatra transfers and the Makassar–Tana Toraja road can consume whole days. Ferries and fast boats are useful for short hops such as Bali–Lombok/Gilis, but are weather-dependent and not a substitute for flights on a tight itinerary.
Money
The currency is the Indonesian rupiah (IDR/Rp). Cards are routine at better hotels, restaurants and shops in Bali and major cities, but carry cash for warungs, small islands, markets, tips and rural transport; ATMs are unreliable or scarce in remote areas. Tipping is not compulsory, but rounding up and modest tips for drivers, guides and porters are appreciated.
Daily budget · Indonesian rupiah (IDR, Rp)
- Value
- Rp700,000–1,300,000 per day
- Mid-range
- Rp1,700,000–3,800,000 per day
- High-end
- From Rp6,000,000 per day; substantially more for Komodo boats, liveaboards and Raja Ampat.
- Bands are per person, based on two people sharing a room, and exclude international flights.
- Value covers clean guesthouses or hostels, local meals, ride-hailing/local transport, entry fees and modest tours. It is comfortable in much of Java and Sumatra but tight in fashionable south Bali.
- The mid-range band is the sensible planning level for a first trip: reliable three- or four-star/boutique hotels, mixed local and restaurant meals, private-driver days or ride-hailing, and paid activities.
- Java and much of Sumatra are markedly cheaper than south Bali, Komodo and Raja Ampat.
- Domestic flights, private drivers, diving, Komodo boat trips, Rinjani treks, surf camps, alcohol and July–August/holiday-period Bali rooms are the major cost escalators.
- Do not budget Raja Ampat as cheap Indonesia: remote transfers, resorts and diving make it a premium expedition destination.
Eating well
- A warung is a small local eatery; choose busy ones with quick turnover, especially for seafood.
- At a rumah makan Padang, many dishes arrive at the table; you pay only for what you eat.
- Lunch is generally noon–2pm and dinner begins from about 6pm.
- During Ramadan, daytime food options can shrink in Muslim-majority areas. At sunset, look for takjil stalls and night markets.
- Bali is one of the few Indonesian regions where pork is central; seek its traditional dishes beyond polished international restaurant districts.
- In Manado and North Sulawesi, ask what meat is in a dish rather than assuming it is standard chicken or beef.
Book before you land
Komodo National Park entry/SIORA registration and a reputable multi-day Komodo boat trip, particularly in dry season · Raja Ampat liveaboards and well-regarded remote dive resorts · Mount Rinjani trekking permits and reputable guided treks in peak season · Borobudur temple-structure access, if that specific visit is important · Java intercity trains around Idul Fitri/Lebaran and Christmas–New Year travel periods
- Indonesia spans three time zones. Treat domestic flights, ferries and airport transfers as travel days rather than trying to stack major sightseeing around them.
- Bali is not representative of Indonesia: it is Hindu-majority and far more tourism-developed than Muslim-majority Java, Sumatra and Sulawesi. Dress more conservatively outside beach and resort areas.
- Remove shoes where asked, use the right hand for giving or receiving food and money, and do not point feet at people or religious objects. At mosques and temples, follow dress rules and do not enter restricted sacred areas.
- During Ramadan, be discreet about eating and drinking in public in conservative areas; travel around Idul Fitri/Lebaran requires very early booking because national movement can overwhelm flights, trains, roads and ferries.
- Use established operators for boats, diving and volcano treks. Cheap Komodo boats and fast-boat crossings are not the place to compromise on safety equipment, crew standards or weather judgment.
- For wildlife, keep distance and do not feed animals. This matters especially with orangutans around Bukit Lawang and with Komodo dragons, where ranger instructions are not optional.
Entry rules change — verify visa requirements for your passport before booking this country.
Season by season
January–March
Java, Bali, Lombok, Flores and much of Sumatra are hot, humid and wet, with heavy afternoon rain and less reliable seas; mountain areas are cooler, while parts of Maluku can be comparatively better timed.

Poorer conditions for volcano trekking, ferry-heavy routes, liveaboards and fixed boat itineraries; holiday periods can still raise prices.
April–June
Rain generally tapers across Java and Bali, vegetation remains lush, visibility improves and conditions are usually favorable for Yogyakarta, East Java volcanoes, Bali, Lombok and Komodo.

Ramadan and especially the Eid al-Fitr homecoming can make domestic transport exceptionally busy, expensive and difficult to book.
July–August
This is generally the driest and sunniest stretch in Java, Bali and Nusa Tenggara, with dependable beach, surf, trekking and Komodo conditions; eastern landscapes turn notably dry.

Peak prices and crowds hit southern Bali, Ubud, the Gilis and Labuan Bajo; reserve good hotels, villas and boats well ahead.
September–October
Dry-season weather often continues across Java, Bali and Komodo after school-holiday crowds recede, though October becomes increasingly variable at sea.

Sea conditions can become less predictable in October, so keep buffer nights before onward or international flights.
November–December
Rain and humidity build across western Indonesia, bringing frequent intense showers and less dependable boat operations, though Bali remains viable for food, wellness, culture and short excursions.

Wet-season bargains disappear around Christmas and New Year, when major domestic movement fills flights, roads, ferries and hotels.
Events worth planning around
Ramadan and Eid al-Fitr (Lebaran/mudik) · Moves annually; Ramadan lasts about a month, with the Eid homecoming period concentrated around its end. · Nationwide, especially Muslim-majority islands and major intercity routes.
This is Indonesia's biggest domestic travel surge: book flights, trains, ferries and accommodation far ahead, or avoid intercity moves around Eid itself. Daytime dining can be reduced outside tourist areas, while sunset food markets are especially lively.
Nyepi, the Balinese Day of Silence · Usually March; date shifts annually under the Balinese calendar. · Bali.
The island largely closes for 24 hours, including the airport; visitors are expected to remain quietly at their accommodation. Do not schedule a one-night Bali stop, flight connection or sightseeing day around it.
Christmas and New Year (Nataru) · Late December to early January. · Nationwide, with particular pressure in Bali and Java.
A major domestic holiday peak despite the wet season. Expect higher prices and heavy demand for flights, ferries, roads and popular accommodation.
What to eat
Treat Indonesian food as a set of regional cuisines, not a checklist of nasi goreng and satay. Use nasi campur for an everyday rice-and-dishes meal, eat at busy warung, and make a point of seeking Padang, Javanese, Balinese, Sasak and Sulawesi cooking rather than defaulting to tourist menus.
