Indonesia travel guide

Indonesia travel guide for 2026

Indonesia is a vast archipelago combining Bali beaches, Javanese temples, active volcanoes, marine parks, rainforest and distinctive island cultures. Because journeys often involve flights, ferries and local transfers, dependable mobile data is especially useful for maps, ride-hailing, accommodation messages and schedule changes.

Get connected before arrival: compare the Indonesia fixed-data eSIM and the Indonesia unlimited-data eSIM. Travellers combining several Asian countries can also consider the Asia regional fixed-data eSIM or Asia regional unlimited eSIM.

Best places to visit in Indonesia

Bali

Combine Ubud's temples and rice terraces with southern beaches, cultural performances and day trips. Denpasar is the main air gateway, while Ubud is a practical inland base.

Yogyakarta and Central Java

Yogyakarta is a major centre for Javanese arts, food and heritage. Borobudur and Prambanan are the headline day trips, and advance booking is sensible during busy periods.

East Java

Mount Bromo and Ijen Crater are among Indonesia's most memorable volcanic landscapes. Surabaya and Malang provide useful transport connections, but early departures and weather-ready packing are important.

Komodo and Flores

Labuan Bajo is the gateway to Komodo National Park. Boat itineraries range from day trips to multi-day cruises, and reservations should be made with reputable operators.

Sumatra and eastern Indonesia

Lake Toba offers volcanic scenery and Batak culture, while Raja Ampat is a premium remote destination for diving and marine biodiversity. These regions require additional transport planning and offline backups.

When to visit Indonesia

May to September is generally the driest period across Java, Bali and many central islands. October and November are transitional, while December to March is wetter in many popular western destinations. Regional patterns differ, so check forecasts for each island rather than relying on one national outlook.

Transport and practical planning

• Use domestic flights for long island-to-island distances.
• Allow buffer time around ferries and weather-sensitive boat trips.
• Download offline maps before remote journeys.
• Keep cash available outside major urban and resort areas.
• Check entry requirements and official weather or volcanic alerts before departure.

Power adapters in Indonesia

Indonesia generally uses Type C and Type F sockets with 230 V and 50 Hz electricity. Travellers using other plug shapes should carry a universal adapter and confirm that devices support 230 V.

How much mobile data do you need?

For a typical two-week itinerary, 10–20 GB is suitable for maps, messaging, bookings and moderate social media use. Unlimited data is better for frequent video, hotspot use, remote work or navigation-heavy multi-island travel.

Indonesia travel FAQs

Is an eSIM useful in Indonesia?

Yes. Mobile data is useful for navigation, transport apps, translation, bookings and communication across a multi-stop itinerary.

Should I choose fixed or unlimited data?

Fixed data is usually economical for maps, messaging and normal browsing. Unlimited data is better for video, hotspot use or remote work.

What is the best month for Bali and Java?

May through September generally provides the driest conditions, although July and August are among the busiest months.

Do I need a power adapter?

Travellers whose devices do not use Type C or F plugs generally need an adapter. Check voltage compatibility as Indonesia uses 230 V.

Can one itinerary include several islands?

Yes, but avoid adding too many transfers. Ten to twenty-one days allows a more comfortable combination of Bali or Java with one additional island region.
