First-Timer's Guide to Indonesia: Essential Travel Tips

Why Indonesia surprises first-timers

Indonesia is huge: more than 17,000 islands spread across three time zones, from the temples of Yogyakarta to the rice terraces of Bali and the reefs of Komodo. A little preparation goes a long way.

Plugs and voltage

Indonesia uses Type C and Type F plugs (the round two-pin European style). The supply is 230V at 50Hz.

• Phones, laptops and most chargers are dual-voltage, so a simple plug adapter is all you need.
• US-only 110V appliances need a converter.
• Bring a small power bank for long ferry rides and temple days.

Language basics

The national language is Bahasa Indonesia, and a few words earn instant smiles:

• Terima kasih - thank you
• Selamat pagi - good morning
• Permisi - excuse me
• Berapa harga? - how much?

English is widely understood in tourist areas of Bali and Jakarta, less so in villages and on smaller islands.

Packing for the climate

Indonesia is hot and humid year-round, with a rainy season roughly November to March.

• Lightweight, breathable clothes plus one sarong (essential for temple visits).
• A modest top covering shoulders and knees for temples and mosques.
• Reef-safe sunscreen, insect repellent and a refillable water bottle.
• A light rain jacket and quick-dry sandals.

Money and getting around

The currency is the Indonesian rupiah (IDR). Carry some cash for warungs (local eateries) and markets, where a meal can cost under 30,000 IDR. Apps like Gojek and Grab make scooters, cars and food delivery cheap and easy in cities.

Six quick tips

• Drink bottled or filtered water only, and skip ice in remote areas.
• Carry small notes - many drivers and stalls cannot break large bills.
• Respect temple etiquette: cover up, remove shoes, never step on offerings.
• Agree taxi or scooter prices before you ride, or use a metered app.
• Watch for Nyepi in Bali (around March), when the island shuts down completely.
• Carry your own toilet paper and hand sanitiser for public restrooms.
