Country guide

Indonesia

Indonesia is between 13,000 and 17,000 islands spread across 1,904,569 km2, the largest archipelagic state in the world, so the question is never what to see but which island to fly to. Over 280 million people live in its 38 provinces and more than half of them on Java alone, the most heavily populated island anywhere and the one carrying Jakarta, the world's most populous city. Sumatra, Sulawesi and the Indonesian portions of Borneo and New Guinea are each a separate trip, across wilderness supporting some of the highest biodiversity on earth. The gaps between them are measured in flights, not in drives.

Common questions

How long should a first trip to Indonesia be?

Ten to fourteen days is enough for Bali plus one nearby island or for a focused Java route, not for the whole archipelago. Every added island introduces an airport or harbour transfer, so choose regions first and count transfer days before assigning sightseeing.

What entry documents are needed for Indonesia?

Indonesia Immigration’s official eVisa service is the source for passport eligibility, visa class and stay conditions. Complete any required arrival formalities through government channels and verify the authorised entry point; a Bali-focused commercial site is not evidence of national admission rules.

What is the best way to travel around Indonesia?

Flights bridge distant islands, Java has useful rail corridors, and ferries, buses or local boats complete many regional legs. Check the licensed operator and weather before sea travel, and leave recovery time when an island connection precedes an international departure.

When is a practical time to visit Indonesia?

Dry-season timing varies across Indonesia, although much of Java and Bali is commonly easier from roughly May to September. Sumatra, Sulawesi and eastern islands can follow different rainfall patterns, so select dates for the chosen islands rather than the country name.

What money and payment basics apply in Indonesia?

Indonesia uses the rupiah, and large IDR figures make digit checking important. Keep cash for markets, drivers and smaller islands, use bank-linked machines where available, and confirm whether an accommodation or boat quote includes taxes and local charges.

What practical safety details should I save for Indonesia?

The recorded emergency contacts are 112 where available and 110 for police; electricity is Type C and F at 230 V. Tap-water safety is Not recorded, so rely on local official or accommodation guidance and verify emergency coverage on remote islands.
