Packing for Indonesia is mostly an exercise in restraint. It is hot and humid almost everywhere, you will be in and out of the water constantly, and you will be carrying your own bag on and off boats more than you expect, so the winning move is to bring less than you think and leave room for a sarong you will inevitably buy. Here is a practical list built around how people actually travel here, from beaches to temples to the odd volcano.
Tailor it to your season with our best time to visit Indonesia guide, and read our safety guide for the travel-insurance and scooter notes.
Clothing: light, modest, quick-drying
Pack light, breathable clothes in quick-drying fabrics, since cotton stays damp in the humidity. You will live in shorts, t-shirts, and swimwear, but bring at least one set of more modest clothing, shoulders and knees covered, for temples, mosques, and conservative areas outside the tourist bubble. A light rain layer is worth it even in the dry season, and if a volcano like Rinjani or Bromo is on your plan, add real warm layers, because the summits are genuinely cold before dawn.
Pack for the cold part of a volcano day, not for the temperature at your hotel. A thin fleece, windproof shell, long trousers and closed shoes can all be worn on the flight, so they do not need to dominate the bag. A bulky insulated jacket is unnecessary for the usual sunrise viewpoints. If the plan is a multi-day Rinjani climb rather than a viewpoint visit, ask the trekking operator what sleeping insulation and rain protection are supplied before duplicating it.
A sarong earns its space even if you buy one after arrival. It covers knees at temples, works as a light blanket on cold transfers and dries faster than a beach towel. Modest dress is not one national uniform, but shoulders and knees covered is a dependable baseline at active places of worship. Keep swimwear for the beach or boat rather than the road through a village.
For the water
This is a country you experience largely in the sea, so pack around water days. Bring your own mask and snorkel if you have them, because rental gear is hit or miss on remote islands. A rash guard is the most practical sun protection for reef trips, and reef-friendly sunscreen fills the gaps. A dry bag is one of the most useful things you can pack, keeping your phone and camera safe on wet boat rides.
Do not rely on a reef-safe claim on the front of a bottle. The UN Environment Programme's Green Fins advice recommends covering up in the sun or choosing products whose active ingredients are only non-nano zinc oxide or titanium dioxide. A long-sleeve rash guard reduces how much sunscreen reaches the water, and not touching or standing on coral matters more than the claim printed on a bottle.
Choose the dry bag for the trip, not for the marketing photograph. Five to ten litres is enough for a phone, wallet and light layer on a day boat. A larger roll-top is useful when the whole bag may sit on a wet deck. A dry bag is splash protection, not permission to submerge electronics, and a transparent phone pouch still needs its seal checked before every use.
Use less sunscreen, not just different sunscreen
A long-sleeve rash guard is kinder to reefs and more reliable than reapplying sunscreen all day. Bring reef-friendly sunscreen for your face, neck, and hands, especially before remote island trips.

The kind of trip this list assumes
Three days two nights on a boat around Komodo National Park, in and out of the water, with your bag in a cabin.
A few practical items earn their space. Indonesia uses Type C and F plugs at 230 volts, the same as most of Europe, so bring the right adapter. A power bank covers long travel days and boats with no sockets. A headlamp is invaluable for pre-dawn volcano climbs and islands with patchy electricity. Pack a basic first-aid kit with rehydration salts and any personal medication, since pharmacies are thin on the ground once you leave the towns.
Power banks belong in cabin baggage, not checked luggage. The current IATA battery guidance says power banks up to 100 watt-hours are generally allowed in carry-on baggage, with terminals protected against short circuit. Its 2026 passenger guidance limits travellers to two, says not to store them in overhead lockers or recharge them on board, and airlines may impose tighter conditions. Check the carrier before travel. The watt-hour figure is printed on reputable power banks; capacity in milliamp-hours alone is not the airline limit.
Download the pieces that become useless without signal: insurance policy, passport copy, onward ticket, hotel address, offline maps and the booking confirmation for the first transfer. Keep a second copy somewhere other than the phone. Remote islands may have enough signal for a message but not enough for a large attachment at the moment somebody at a jetty asks to see it.
Money, documents and health
Carry enough rupiah for remote stretches, because ATMs vanish on small islands and cards are unreliable outside cities and tourist towns. Keep digital and paper copies of your passport, visa, arrival card, and insurance separate from the originals. Travel insurance that covers boats, diving, trekking, and scooters is essential. Bring mosquito repellent, rehydration salts, and any prescriptions you rely on; some medicines that are legal elsewhere can be restricted in Indonesia, so check before packing controlled medication.
Mosquito planning depends on the route. The CDC Indonesia traveler page lists malaria transmission in parts of eastern Indonesia and rural areas of several provinces while listing Jakarta, the resort areas of Bali and Java, and the Gili Islands as no-risk. That is a medical decision, not a packing-list guess. Take the itinerary to a travel clinician and discuss prophylaxis early enough to choose and start it correctly.
Carry prescription medicine in its labelled packaging, with the prescription and a short clinician letter naming the generic drug and daily dose. Indonesian consular guidance says travellers must declare personal medication through All Indonesia and be ready to show the letter or original prescription to customs. Bring enough for the visit and check the rules before travelling with controlled medicine. A pharmacy in a provincial capital is not a substitute for a specific drug while you are already on an island.
What to leave at home
Resist the urge to overpack. You do not need a week’s worth of outfits, a hairdryer, or heavy hiking boots unless you are doing a serious volcano trek. Laundry is cheap and everywhere, so a few days’ clothes cycle fine. Hard suitcases are a liability on small boats and rough jetties; a soft backpack or duffel is far easier to handle. The lighter you pack, the more you will enjoy the parts of this trip that involve lifting your own bag into a wooden boat.
The same restraint applies to specialist equipment. Fins, trekking poles, a large camera housing and a laptop can each be sensible for the right trip, but not by default. Rental quality varies, so bring equipment whose fit affects safety, such as a prescription mask or broken-in walking shoes. Rent the bulky item that you only need for one day, after confirming availability with the operator.
Do not fill every spare corner with toiletries. Common shampoo, toothpaste and basic first-aid supplies are easy to replace in towns. The exceptions are products you cannot safely substitute, prescription medicine, high-strength repellent you already tolerate, and enough sun protection for the remote section before the next town. That distinction keeps the bag small without pretending every island has a full pharmacy.
The short list
If you remember nothing else: light quick-dry clothes, one modest outfit, swimwear and a rash guard, reef-safe sunscreen, your own mask, a dry bag, a power bank, a headlamp, plenty of cash, and travel insurance. Add warm layers only if a volcano is on the agenda. Then check the season for where you are going in our best time to visit guide, and plan the trip with us.

Frequently asked questions
What should I pack for Indonesia?
Light, quick-drying clothes, swimwear and a rash guard, one modest outfit for temples, reef-safe sunscreen, your own snorkel mask, a dry bag, a power bank, a headlamp, plenty of cash, and travel insurance. Add warm layers if you are climbing a volcano.
What plug adapter do I need for Indonesia?
Indonesia uses Type C and F plugs at 230 volts, the same as most of continental Europe. Bring the right adapter, and a power bank for long boat and travel days.
Do I need reef-safe sunscreen in Indonesia?
Yes, ideally. A rash guard is even better because it reduces how much sunscreen you need. Reef-friendly sunscreen can be harder to find on remote islands, so buy it before you go if you plan to snorkel or dive.
Should I pack hiking boots for Indonesia?
Only if you are doing a serious volcano trek like Rinjani. For everyday travel, sandals and trainers are enough. Lightweight, broken-in shoes beat heavy boots for general use.
How much cash should I bring to Indonesia?
Enough to cover remote stretches where ATMs are scarce and cards useless, such as the Banggai Islands or Raja Ampat. Withdraw rupiah in the cities before heading somewhere remote.
