Connectivity and Finances
Buy a Telkomsel SIM card immediately upon arrival for the best coverage, especially if you plan to travel beyond South Bali. Airport counters are convenient but usually more expensive; official shops in town can register your passport and phone for a better price. Use apps like GoJek and Grab for transport and food delivery, because they reduce street negotiations and show a fair price before you move. See our transport guide for more details.
Money, ATMs, and Daily Costs
Carry a mix of cards and cash. Cards work in hotels, larger restaurants, and malls, but small warungs, local buses, market stalls, and homestays often prefer cash. Use ATMs attached to banks, decline dynamic currency conversion, and keep small notes for taxis, temple donations, and parking attendants. If you are watching costs, compare daily spending ideas in our Indonesia budget guide.
Respect Local Culture
Indonesia is diverse. What works in Bali is often different on Java, Lombok, or Sumatra. Dress modestly outside beach and resort zones, ask before photographing ceremonies, and avoid stepping over offerings in Bali. A smile and calm tone open more doors than getting angry over delays, because traffic, ferries, weather, and religious events can change plans quickly.
- Always wear a sarong and sash in temples.
- Use your right hand for giving, receiving, and eating.
- Take prayer times into account on Java and in Muslim-majority areas.
- Remove your shoes before entering homes and some small guesthouses.
Island-Hopping Without Stress
Do not underestimate travel time between islands. A short distance on the map can become a full travel day when you include hotel pickup, port delays, ferries, and traffic after arrival. Build buffer days around domestic flights, boat transfers, and volcano or waterfall trips. For a balanced route that avoids constant packing, start with our Java and Bali itinerary.
Packing for Different Islands
Pack for heat, rain, and modesty at the same time. A light long-sleeve shirt protects against sun and mosquitoes, while a thin rain jacket is useful even in the dry season. Bring a power bank for long transfers, a dry bag for boat days, and a small medical kit with rehydration salts. Shoes matter too: sandals are fine in beach towns, but trainers make temple steps, waterfalls, and uneven pavements much easier.
Food, Water, and Everyday Etiquette
Street food is part of the joy of Indonesia, but choose busy stalls where ingredients are cooked fresh. If you are unsure, start with simple dishes such as nasi goreng, mie goreng, soto ayam, gado-gado, or grilled fish. Say terima kasih when you are served, avoid touching anyone's head, and keep public affection discreet in conservative areas. These small choices help you travel smoothly and respectfully.
Health and Practical Safety
Drink bottled or filtered water, use sunscreen earlier than you think, and carry mosquito repellent for evenings near rice fields or rivers. Travel insurance matters because scooter accidents and missed ferry connections are common visitor problems. If you rent a scooter, wear a helmet, check the brakes, photograph existing damage, and make sure your licence and insurance actually cover riding.
