The essentials
Before you go
- Visa and entry
- Eligible passports can use the B1 visa on arrival: Rp500,000 for 30 days, extendable once for another 30. Check your own eligibility before travel, and submit the electronic arrival card in the three days before you land.
- Money and cards
- The rupiah. Visa and Mastercard work in cities, hotels and tourist centres; carry cash for warungs, markets, drivers and the smaller islands. Use bank ATMs, withdraw less often and decline home-currency conversion.
- Getting around
- Rail is genuinely useful on Java and nowhere else. Domestic flights link the island groups, ferries are slower and weather-exposed, and supported ASDP routes are bookable through Ferizy. Leave slack between separate tickets.
- Connectivity
- Local SIMs require passport registration. Tourist prepaid offers run roughly Rp100,000–150,000 for about 25GB over 30 days; official pickup points and rural coverage vary, so check before relying on eSIM alone.
- Language
- Bahasa Indonesia is the national language. English is workable in the visitor hubs and much thinner elsewhere; save addresses, ferry names and hotel details as map pins or in Indonesian.
- Water and health
- Do not assume tap water is drinkable: use sealed, boiled or reliably filtered water. Dengue is a mosquito risk and malaria advice varies by island, so use repellent and check current guidance for your route.
