Indonesia Is Vast — Plan Accordingly

Indonesia is the world's largest archipelago nation, spanning over 17,000 islands across a distance roughly equivalent to the width of the continental United States. Many first-time visitors underestimate how much internal travel is involved. Pick a region and go deep rather than trying to see everything — attempting to cover Bali, Java, Lombok, Flores, and Sulawesi in two weeks will leave you exhausted and underwhelmed at each stop.

1. Visa Basics

Citizens of many countries can enter Indonesia visa-free for stays up to 30 days (check the latest regulations before travel, as policies change). The Visa on Arrival (VOA) is available at major ports of entry and can be extended once for an additional 30 days. For longer stays, a social or tourist visa should be arranged in advance through an Indonesian embassy.

2. Best Time to Visit

Indonesia straddles the equator and has two main seasons: dry (April–October) and wet (November–March). The dry season is generally the best time for most destinations. However, due to Indonesia's size, weather varies significantly — while Bali is wet in December, parts of Sulawesi may be dry. Always check the specific region you're visiting.

3. Getting Around

  • Domestic flights: Essential for covering long distances. Airlines like Garuda Indonesia, Lion Air, and Citilink connect major cities and islands affordably.
  • Trains (Java): Java has an excellent rail network. Booking through the official KAI website is recommended.
  • Ferries: ASDP ferries connect many islands, including the busy Bali–Lombok and Java–Bali crossings.
  • Ojek & Gojek: Motorcycle taxis (ojek) are the fastest way around cities. The Gojek and Grab apps make this incredibly convenient and fairly priced.

4. Money and Payments

Indonesia uses the Indonesian Rupiah (IDR). Notes come in large denominations — a 100,000 Rupiah note is roughly USD 6–7. ATMs are widely available in cities and tourist areas; less so in remote regions. Carry sufficient cash when venturing off the beaten track. Many markets and warungs are cash-only.

5. Dress Respectfully

Indonesia is the world's most populous Muslim-majority nation. Outside of Bali's beach zones and tourist areas, dress modestly — cover shoulders and knees when visiting markets, villages, mosques, or government buildings. At Hindu temples in Bali, wearing a sarong and sash is mandatory and usually available to borrow at the entrance.

6. The Left Hand Rule

Across Indonesia (as in much of Southeast Asia and Muslim cultures), the left hand is traditionally considered unclean. Use your right hand for giving and receiving items, eating, and greeting people. This small gesture of cultural awareness is always appreciated.

7. Bargaining Is Normal (In the Right Places)

At markets and independent souvenir stalls, light bargaining is expected. At restaurants, shops with price tags, and transport apps, prices are fixed. A friendly, good-natured approach works far better than aggressive negotiation.

8. Tap Water Is Not Safe to Drink

Drink bottled or filtered water only. Most accommodations provide free bottled water or have filtered water stations. To reduce plastic waste, carry a refillable bottle and use water refill services available in many tourist areas.

9. Electricity

Indonesia uses Type C and Type F plugs (round two-pin) at 220V / 50Hz. Bring appropriate adapters if your devices use other plug types.

10. Learn a Few Words of Bahasa Indonesia

Indonesians are genuinely delighted when visitors attempt their language. A few phrases go a long way:

  • Terima kasih — Thank you
  • Permisi — Excuse me
  • Berapa harganya? — How much is it?
  • Enak sekali! — Very delicious!
  • Selamat pagi / siang / malam — Good morning / afternoon / evening

11. Health Precautions

Consult a travel health clinic before departure. Common considerations include hepatitis A and typhoid vaccinations, malaria prophylaxis for certain rural or eastern island areas, and dengue fever awareness. Travel insurance that covers medical evacuation is strongly recommended.

12. Embrace Jam Karet

Indonesians have a concept known as jam karet — "rubber time" — meaning schedules and timing are flexible. Buses run late, meetings start late, and things generally happen when they happen. Fighting this will only stress you out. Relax, bring a book, and enjoy the pace. It's part of what makes travel in Indonesia so refreshingly human.
