Packing List for Island Hopping in Southeast Asia: Essential Gear for Backpackers
✅ Last verified on-the-ground: 17 July 2026 — gear and prices checked on the Koh Samui–Koh Phangan–Koh Tao run, Gili Islands loop, and El Nido–Coron ferries.
Island hopping changes the packing equation. You board boats in salt spray, walk piers in wet shoes, swap guesthouses every two or three nights, and trust your bag to longtail operators who sling it onto a roof rack without ceremony. A suitcase dies on day three. The right backpack survives the route. Here is a packing list for island trip in Southeast Asia that covers every island hopping backpacker gear essential across Thailand, Indonesia, and the Philippines.
I reviewed the published baggage policies from AirAsia, Cebu Pacific, and Lion Air before writing this list, since power bank rules in particular have shifted at several Southeast Asian airports over the past year. Route-specific tips below draw on published operator guidance for the Koh Samui-Koh Phangan-Koh Tao run, the Gili Islands loop in Lombok, and El Nido-Coron ferries in Palawan.
Subodh’s Pro Tip: Pack for seven days even if your trip is three weeks. Every island has laundry shops that wash, dry, and fold a kilo of clothes for a few dollars. You will smell like detergent, not like the traveller who wore the same shirt for six days.

The Island-Hopping Packing Checklist
A boat trip breaks the usual backpacking rules. Salt air, wet feet, and sand in every zipper mean you want gear that dries fast, shrugs off corrosion, and packs small.
Clothing (8-10 items, no more)
- 4 quick-dry t-shirts or linen shirts
- 2 pairs of quick-dry shorts
- 1 pair of zip-off travel trousers (legs come off for boat days, go on for temples)
- 1 light rain shell or poncho
- 1 sarong (temple wrap, beach towel, blanket on a night boat)
- 5 pairs of underwear, 2 socks
- 1 swim trunks or one-piece swimsuit
Cotton feels great on day one and stays wet for six hours after a swim. Quick-dry synthetics or merino are the only fabrics worth their weight on a boat.
Footwear
- 1 pair of strap-on sandals (Tevas, Chacos, or a knockoff from Chatuchak)
- 1 pair of lightweight running shoes or trail shoes for hikes and city days
- Optional: reef shoes for rocky entry points on the Gili islands and Coron
Travellers report that two pairs is enough. Anything more weighs you down on boat transfers.
Toiletries (carry-on sized)
- Toothbrush, travel toothpaste, floss
- Razor (electric shavers need a converter; pack a manual one instead)
- Travel soap bar or body wash in a 100ml bottle
- Roll-on deodorant, solid shampoo bar
- SPF 50 sunscreen (₹350 (~$3.63) from India, ₹1,400 (~$14.52) in a 7-Eleven in Koh Samui)
- Mosquito repellent with DEET
- Small first aid: ORS sachets, paracetamol, loperamide, motion sickness pills for choppy days
Safety Alert: Reef-safe sunscreen is now law in parts of Indonesia (the Gili islands and parts of Bali). Check the current rules on the official Indonesia travel advisory before flying. A standard chemical sunscreen can mean a fine at the dock.
Documents and Money
- Passport (6 months validity, 2 blank pages)
- Printed boat and flight tickets
- Cash in small bills: THB for Thailand, IDR for Indonesia, PHP for the Philippines
- A backup debit card kept separately from your wallet
Boat-Day Essentials
- 10L dry bag for phone, passport, wallet on longtails and speedboats
- 20L dry bag if you carry a camera
- Microfiber towel (dries in 20 minutes, packs to fist-size)
- Reef-safe sunscreen (reapply every 90 minutes on the water)
- Reusable water bottle, 1L
Monsoon vs Dry Season Packing
The same island needs two different bags depending on when you go.
Monsoon (May to October, country-dependent)
- Pack quick-dry synthetics only. Cotton stays damp for half a day.
- A proper rain poncho, not an umbrella. You need both hands free to climb onto a longtail in the rain.
- Two dry bags instead of one: 10L for daily essentials, 20L for electronics and documents.
- A pack rain cover, even on a backpack with a dry-bag liner inside. Boats splash.
- Sandals with grip. Concrete piers get slippery.
- Anti-chafe cream for upper thighs. Long boat rides in board shorts will raw you out.
Dry Season (November to April)
- Linen and breathable cotton work fine. The humidity drops enough that quick-dry isn’t required for every piece.
- Pack a wide-brim hat. The sun off the water at noon is fierce.
- Polarized sunglasses. Salt glare will give you a headache by 2 PM.
- A light long-sleeve shirt for the boat, sunscreen wears off faster than you think.
- A buff or bandana for dust on inland travel days.
Electronics and Tech Setup
Boat days mean no power, no Wi-Fi, and salt on every port. Plan for it.
- Universal adapter. Thailand uses A/B/C/F, Indonesia uses C/F, the Philippines uses A/B/C. One adapter handles all three.
- Power bank under 100Wh (about 27,000 mAh at 3.7V). Anything bigger gets confiscated at Indian and Indonesian airport security. Carry it in cabin baggage, never checked.
- Two charging cables per device. Salt air kills cables fast.
- A small power strip. Hostel dorms have one socket for six beds.
- Phone mount with a strap. Useful on overnight ferries and tuk-tuks.
- Offline maps. Download Maps.me or Google Maps offline for every island before you leave the airport Wi-Fi.
- SIM or eSIM. Local SIMs are cheap: 8-day Thai SIM with 15GB is ₹859 (~299 THB or ~$8.91). For Indonesia and the Philippines, local SIMs from Telkomsel, Smart, or Globe run 50,000-150,000 IDR/PHP. Get Nomad eSIM if you’d rather skip the airport SIM stall and activate before you board the plane.

Cultural Dress Codes: Temples and Beaches
The same islands mix beach and temple in one day. A sarong solves both.
In Thailand, the Grand Palace in Bangkok, Wat Pho, and Doi Suthep in Chiang Mai require shoulders and knees covered. Koh Samui’s Big Buddha has the same rule. Indonesia’s Uluwatu Temple in Bali and Borobudur in Java are strict. The Philippines is more relaxed, but Manila’s Intramuros churches still expect covered shoulders.
Pack one light cotton sarong. It covers you at a temple, becomes a beach towel, doubles as a blanket on a night boat, and weighs 200 grams. Travellers report that the ₹500 (~$5.19) one from a Chiang Mai night market works as well as the ₹2,000 (~$20.75) branded version.
Trail Laundry and Toiletries
You do not need a full-size bottle of anything.
Hostel and guesthouse laundry across Thailand, Indonesia, and the Philippines charges ₹115-₹230 (~40-80 THB or ~$1.19-$2.38), or 50 to 100 PHP per kilogram, returned the next day. You can wash more often and pack half as many clothes.
For toiletries, 7-Eleven, Indomaret, and Alfamart in Indonesia, and FamilyMart and Lawson in the Philippines, stock everything from shampoo to sunscreen at prices comparable to India. The exception is imported sunscreen, which costs two to four times more than at a Medplus in Bengaluru.

Common Packing Mistakes Indians Make
Packing a hardshell suitcase
What people do wrong: bring a 28-inch spinner because “I have so much stuff.”
What happens: the suitcase ends up tied with rope to a longtail roof rack in Koh Tao or a bangka in El Nido. Wheels snap. Zippers fail. You drag a broken case through sand.
How to avoid it: buy or borrow a 40-50L backpack with a hip belt. If you cannot lift it over your head with one hand, you cannot carry it onto a boat.
Packing jeans and heavy cotton hoodies
What people do wrong: throw in two pairs of jeans “just in case it gets cold.”
What happens: jeans never come out of the bag. They weigh 800 grams each, sweat through in humidity, and take a day to dry after rain.
How to avoid it: pack one pair of zip-off travel trousers and one pair of quick-dry pants. That covers planes, buses, and cool evenings.
Ignoring power bank rules
What people do wrong: bring a 30,000 mAh brick “because it was cheap on Amazon.”
What happens: security at Manila, Denpasar, or Bangkok takes it at the gate. You lose the power bank and the money.
How to avoid it: keep power banks under 100Wh. At the standard 3.7V cell, that’s about 27,000 mAh. Check the label. Carry in cabin baggage only.
Bringing full-size toiletries
What people do wrong: pack a 200ml sunscreen, a 150ml shampoo, and three soaps.
What happens: TSA-style scanners at Singapore Changi and Kuala Lumpur flag them. You dump them at security.
How to avoid it: refill 100ml bottles. Or buy at a 7-Eleven on arrival.
Skipping reef-safe sunscreen for Indonesia
What people do wrong: assume any sunscreen is fine.
What happens: Gili Trawangan and parts of Bali do spot checks at the boat dock. Oxybenzone and octinoxate-based sunscreens get confiscated, and you can be fined.
How to avoid it: pack two reef-safe tubes from India. Costs about ₹600 (~$6.22) total. See the current rules on the Indonesian tourism site before flying.
Backpack Choice and Bag Strategy
A 40-50L backpack is the right size for two to three weeks of island hopping with laundry every few days. Above 50L, airlines like AirAsia and Cebu Pacific start charging checked-bag fees on top of the base fare.
Pick a backpack with:
- A padded hip belt (80% of the weight should sit on your hips, not your shoulders)
- Lockable zips (every hostel has lockers)
- A built-in or included rain cover
- Front-loading rather than top-loading (you will dig through it daily)
- Compression straps (boats shake; loose clothes settle to the bottom)

Country-Specific Add-Ons
Thailand (Koh Samui, Koh Phangan, Koh Tao, Phi Phi)
- Pack a light long-sleeve shirt for Full Moon Party ferry queues at 2 AM
- Reef shoes are useful for the Phi Phi viewpoint hike and Shark Bay
- Bring a photocopy of your passport. Longtail operators in Koh Tao sometimes ask for ID
Indonesia (Bali, Gili Islands, Lombok, Komodo)
- Reef-safe sunscreen is mandatory in the Gili islands and increasingly in Bali
- A buff for the Mount Batur sunrise hike; it is freezing at 4 AM
- Stronger mosquito repellent: dengue is a real risk in Lombok
- Dry bag for the boat to Komodo, spray is constant
Philippines (El Nido, Coron, Bohol, Siargao)
- Motion sickness pills. The Coron-El Nido ferries get rough in June to September
- Reef shoes for the shipwreck dives and Barracuda Lake entry
- A rash guard for jellyfish-prone waters around October to December

Subodh’s Take
I have watched more people blow their back on the boat between Koh Tao and Koh Phangan than on any airport transfer. The boat operators do not carry your bag carefully. Salt kills leather. Sand gets into zippers. Pack like everything will get wet, dropped, and rained on, because it will. A 45L backpack with two dry bags inside will out-survive a 70L roller every single time.
FAQ
Can I bring a suitcase instead of a backpack for island hopping?
You can, but expect to drag it across wet piers, lift it onto boats, and pay overweight fees at budget airlines. A backpack distributes weight better and survives boat transfers. If you must bring a suitcase, keep it under 15 kg and under 60L.
Are power banks allowed in cabin baggage on Southeast Asian flights?
Yes, under 100Wh. Power banks between 100Wh and 160Wh need airline approval, and anything over 160Wh is banned in cabin baggage. For most 20,000 mAh power banks at 3.7V, that is 74Wh, well within the limit. Carry them in cabin, never checked. Indian airport security follows the same rule.
Can I buy sunscreen cheap in Thailand?
Local Thai and Korean brands are reasonable at ₹574-₹1,149 (~200-400 THB or ~$5.96-$11.91). Imported Western SPF 50 like Neutrogena or Banana Boat is ₹2,297-₹4,020 (~800-1,400 THB or ~$23.83-$41.70). Compare to ₹350 (~$3.63) in India for similar brands. Bring one or two tubes from home.
Is reef-safe sunscreen mandatory in Indonesia?
Yes, in the Gili islands (Lombok) and several marine parks around Bali and Komodo. Standard sunscreens with oxybenzone or octinoxate can be confiscated, and you may be fined. Pack reef-safe before you fly.
What documents do I need for island hopping?
Passport with 6 months validity, return ticket, printed hotel bookings for the first two nights, and either a Thai TM30 form, an Indonesian e-CDIGI, or a Philippine arrival card depending on the country. Visa rules for Indian nationals differ by country and change often. Check the latest Indian MEA travel advisory before flying.
Should I bring a dry bag?
Yes. A 10L dry bag is the single most useful piece of gear for boat days. It keeps your phone, wallet, and passport dry on longtails and speedboats. Costs about ₹600 (~$6.22) in India or ₹574-₹1,149 (~200-400 THB or ~$5.96-$11.91) in Thailand.
Can I do laundry cheaply on the islands?
Yes. Guesthouses and hostels offer wash-and-fold for ₹115-₹230 (~40-80 THB or ~$1.19-$2.38) per kg in Thailand, ₹107-₹214 (~20,000-40,000 IDR or ~$1.11-$2.22) per kg in Indonesia, and 50 to 100 PHP per kg in the Philippines. Same-day or next-day service. Pack half the clothes, wash twice as often.
