Practical Guide to Traveling in Indonesia

Updated: 2026-07-20 · by Viaje365 Editorial Team

Indonesia is an archipelago of more than 17,000 islands, so the travel experience changes radically between Bali, Jakarta, Lombok, or the less touristy islands. The dry season, between May and September, is the most recommended for most of the country.

The entry process is usually simple for a large share of nationalities thanks to visa on arrival or full exemption, but it's worth confirming in advance according to your own passport.

Indonesia sits on the so-called Pacific "Ring of Fire," with active volcanic and seismic activity; combined with dengue risk and the varying quality of medical care outside the main tourist centers, travel insurance with medical evacuation coverage is a very reasonable precaution.

Visa and health for travelers

Visa: Many nationalities can get a short-term visa on arrival by paying a fee at the airport, while others have full exemption or must apply for a visa in advance. The exact category depends on the traveler's passport; check Indonesia's official immigration portal before traveling.

Health & travel insurance: Between dengue risk, volcanic and seismic activity, and hospitals of varying quality outside Bali or Jakarta, travel medical insurance with evacuation coverage is especially valuable in Indonesia, particularly if the itinerary includes remote islands.

Visa and entry requirements

Indonesia offers visa on arrival for numerous nationalities, generally valid for 30 days and payable at the airport or electronically in advance. Other nationalities enjoy full visa exemption for shorter periods, and some must obtain a consular visa before traveling. The passport must have a minimum validity of 6 months.

Best time to travel

The dry season (May-September) offers the most stable weather in Bali, Java, and most of the tourist islands. The rainy season (October-April) brings more humidity and intense but short-lived downpours, especially between December and February.

Health, natural risk, and travel medical insurance

Dengue is present year-round, and hospital quality varies greatly between Bali/Jakarta (good quality) and rural areas or remote islands (limited). Volcanic and seismic activity is real and occasionally affects travel routes. In any of these scenarios, travel medical insurance such as Assist-365 plans is key, especially for its medical evacuation coverage; code MEDALLOADV2023 gives an immediate discount when you get a quote.

Safety and practical tips

Indonesia is generally safe for tourism, although it's worth staying informed about tsunami alerts, active volcanic activity (for example, near certain volcanoes in Java or Bali), and respecting access restrictions when local authorities issue them. In Bali, accidents involving rented motorbikes are common among tourists.
