01
Is Indonesia right for your trip?
Indonesia is a strong choice for travellers who want major cities, volcanic landscapes, temples, beaches, islands, wildlife and highly varied regional cultures.
Java, Bali, Sumatra, Lombok, Flores, Sulawesi and Kalimantan require very different transport, weather and time commitments.
A successful first trip usually combines Java with one island extension rather than trying to cover the entire country.
- Excellent for culture, nature and independent travel.
- Strong variety across different islands.
- Domestic flights often save substantial time.
- Ferry and road journeys can take longer than expected.
- Twelve full days is the practical minimum for a balanced first trip.
02
When should you visit?
Weather differs by island, but many popular regions are generally easiest during their drier months.
Rainfall, humidity and sea conditions vary significantly across the archipelago.
Ramadan, Eid, school holidays and local festivals can affect transport, opening hours and prices.
- Java and Bali: often driest from roughly May to October.
- Wet-season timing varies by island.
- Mountain weather can change quickly.
- Sea crossings depend on local conditions.
- Check regional forecasts rather than one national forecast.
Important
Volcanic activity, flooding, landslides and rough seas can disrupt routes with little notice. Keep flexible transfer days.
03
What must you check before entering Indonesia?
Entry requirements depend on nationality, passport, travel purpose and the type of visa or electronic authorisation required.
Use only official Indonesian immigration sources for visa and arrival information.
Check whether your intended airport or seaport supports the entry permission you plan to use.
- Confirm the correct visa category.
- Check passport-validity requirements.
- Verify permitted entry points.
- Review onward-travel requirements.
- Carry accommodation details.
- Keep immigration documents available offline.
04
How many days do you need?
Twelve to eighteen full days gives enough time for Jakarta, Yogyakarta and one major island extension.
The most common mistake is trying to combine Java, Bali, Lombok, Komodo and Sumatra in one short trip.
- 7 days: one region only.
- 12 days: Jakarta, Yogyakarta and one focused extension.
- 18 days: add Bali, Lombok or eastern Java.
- 21+ days: combine several islands without constant transit.
05
What is a realistic first-time route?
A strong first route combines Jakarta, Yogyakarta, eastern Java and one island extension.
Open-jaw flights can reduce backtracking—for example, arrive in Jakarta and depart from Bali.
- Days 1–3: Jakarta.
- Days 4–7: Yogyakarta and nearby temples.
- Days 8–10: eastern Java or another focused overland section.
- Days 11–16: Bali, Lombok or another chosen island.
06
When do domestic flights make sense?
Domestic flights are often the only practical option between distant islands.
- Compare total travel time, not airfare alone.
- Check baggage rules before booking.
- Confirm the exact airport.
- Allow time for weather delays.
- Keep boarding passes available offline.
- Avoid tight self-transfers on separate tickets.
07
When do trains make sense?
Java’s rail network is useful for major city pairs and scenic overland travel.
- Reserve popular routes in advance.
- Check the exact station.
- Choose the correct carriage class.
- Keep valuables with you.
- Arrive early.
- Compare daytime scenery with overnight travel time.
08
How should you plan ferries and boats?
Ferry quality, schedules and sea conditions vary widely across Indonesia.
- Use established operators.
- Check sea and weather conditions.
- Confirm the exact port.
- Keep luggage protected from water.
- Avoid unsafe or overloaded boats.
- Allow buffer time before onward flights.
09
When should you use a private driver?
Private drivers are useful for temple routes, rural areas, volcano transfers and regions with limited public transport.
- Agree on the route and total price.
- Confirm whether parking and tolls are included.
- Use recommended or established providers.
- Avoid overly long driving days.
- Keep accommodation details offline.
- Confirm pickup times the day before.
10
How should you choose accommodation?
Choose accommodation by neighbourhood, transport access, noise, climate control and early-departure logistics.
- Check the exact neighbourhood.
- Review recent guest feedback.
- Confirm air-conditioning.
- Check street-noise comments.
- Review airport, station and port transfers.
- Save the exact address offline.
11
What should you eat?
Indonesian cuisine varies strongly by region and is one of the main reasons to travel across the country.

- Try rendang.

12
How should you approach street food?
Street food is central to daily life, but hygiene, heat and unclear ordering can create practical challenges.
- Choose busy stalls.
- Watch how food is stored and cooked.
- Carry small cash.
- Learn a few dish names.
- Avoid food left unrefrigerated for long periods.
- Use a guide for a first introduction if needed.

- Carry a second payment card.
- Keep small notes for markets and transport.
- Check the number of zeros before paying.

- Check coverage for rural and island routes.
- Download offline maps.
- Save hotel addresses offline.
- Keep booking confirmations offline.
- Carry a power bank.
15
What should you know about etiquette?

- Dress modestly at religious sites.
- Remove shoes where requested.
- Ask before photographing people.
- Use your right hand when giving or receiving items.
- Respect prayer times and local ceremonies.
