What should I pack for Thailand?

Light, breathable cotton or linen clothing for daytime; one set of long, modest clothing for temples; swimwear; sturdy walking sandals plus closed shoes for treks; sun protection (high-SPF sunscreen, hat, sunglasses); a power bank and Thai/EU/US-style adapter; basic toiletries (most are available locally); a small first-aid kit including paracetamol, ibuprofen, and rehydration salts; mosquito repellent with DEET; printed copies of your passport, visa, and insurance. Pack lighter than you think — Thailand has cheap, fast laundry everywhere.

Do I need to bring sunscreen to Thailand?

It is easier to bring it. Thailand sells sunscreen, but most local brands include skin-whitening agents and SPFs above 30 are limited and expensive. Western brands (Banana Boat, Hawaiian Tropic, Nivea) are sold at 7-Eleven and Boots in tourist areas at 2–3x home prices. Bring SPF 50+ in a large bottle from home — this is one item that pays to pre-pack. Reef-safe sunscreen is increasingly mandated at marine parks (notably Koh Tao and Mu Ko Similan); bring a small bottle if you snorkel.

What kind of clothes are appropriate in Thailand?

For most situations, light casual clothing is fine — shorts, t-shirts, sundresses, sandals. Bangkok is cosmopolitan; rooftop bars sometimes enforce smart casual (closed shoes, no tank tops for men). Temples require knees and shoulders covered for both men and women — pack one pair of loose lightweight trousers and a long-sleeve top or a sarong (lightweight wrap, easily packed, good for spontaneous temple stops). Beaches are casual; topless sunbathing is technically illegal and culturally inappropriate, particularly outside Phuket and Pattaya.

Do I need a power adapter for Thailand?

Thailand uses 220V at 50Hz with mostly Type A (US-style two flat pins), Type B (US three-pin grounded), and Type C (European two round pins) sockets — often all three on the same outlet. UK three-pin and Australian flat-pin plugs do not fit. Bring a universal travel adapter or a Thailand-specific adapter; both are sold locally for 100–200 THB if you forget. Modern electronics (phones, laptops) handle 220V automatically; check the label of older devices like hairdryers or shavers — using 110V-only devices on Thai 220V will burn them out.

Should I bring mosquito repellent to Thailand?

Yes. Thai mosquitos are persistent in evenings and around water, and Dengue fever is a real risk in some areas (urban Bangkok, the south, and during rainy season). Bring repellent with at least 25% DEET (or 20%+ Picaridin if you prefer), a small bottle. Local brands (Sketolene, Soffell) are effective and cheap if you run out — sold at every 7-Eleven. For sleeping in cheaper accommodation without mosquito screens, pack a lightweight mosquito net or stay somewhere with screens and AC (mosquitoes are sluggish at low temperatures).

Do I need walking shoes for Thailand?

It depends on plans. For beach holidays plus city sightseeing, sturdy walking sandals (Teva, Keen, Chaco) handle 95% of situations — comfortable for long days, dry quickly after monsoon downpours, and easy to slip off at temples. For trekking in the north (Doi Inthanon, Mae Hong Son loop, Khao Sok rainforest), bring proper trail shoes with grip. For city evenings out, one pair of closed shoes or smarter sandals is useful for upscale restaurants and rooftop bars. Skip heavy hiking boots unless you are doing serious multi-day treks.

What medications should I bring to Thailand?

Bring a small first-aid kit with paracetamol, ibuprofen, antihistamines, anti-diarrhoeal (Imodium), oral rehydration salts (ORS), antiseptic cream, plasters, and any prescription medication you take regularly with prescription documentation. Most of these are sold cheaply at 7-Eleven and pharmacies (Boots, Watsons), but having your own avoids midnight pharmacy hunts. For prescription drugs: bring enough for the entire trip plus a buffer, in original packaging with a copy of the prescription. Some controlled substances (ADHD medications, strong opioids) require advance notification to Thai customs.

Should I pack jeans for Thailand?

Generally no — jeans are too hot and slow to dry in Thai humidity. If you must pack one pair (for evenings out at upscale Bangkok restaurants or Chiang Mai night markets when it cools off), choose lightweight stretch fabric. For everyday wear, light cotton trousers, linen, or chinos are far more comfortable. Smart casual evening attire in Bangkok works in lightweight chinos, a button-down shirt, and closed shoes.

What is the best bag to bring to Thailand?

For 90% of travellers, a 40–60L wheeled travel backpack or a 65–75L proper backpack works best. Wheeled bags handle smooth surfaces (Bangkok, hotel transfers); backpacks handle stairs, ferries, and rough beach terrain. A daypack (15–25L) is essential — for day trips, beach essentials, and as a carry-on. Avoid hard-shell suitcases; they wreck on Thai songthaews, ferries, and overnight bus storage. Whatever bag you choose, pack to under 70% capacity to leave room for inevitable shopping.

Do I need a sleeping bag or travel sheet in Thailand?

Sleeping bag: only for budget treks in northern hill country during cool season (December–February) — most operators provide bedding. Travel sheet (silk or cotton liner): useful if you stay in budget guesthouses, hostel dorms, or do longer overnight transport. For mid-range hotels, AirBnBs, and resorts, sheets are clean and you do not need anything extra. Light long-sleeve thermals are useful for over-air-conditioned overnight buses and trains, which can drop to 16°C.

How much luggage can I bring on Thai domestic flights?

Budget airlines (AirAsia, Nok Air, Thai Lion Air) typically include 7–10kg carry-on only; checked baggage is paid extra (300–500 THB at booking, 1,000+ THB at check-in). Add baggage when booking the ticket — adding it at the airport is significantly more expensive. Thai Airways and Bangkok Airways include 20–30kg checked baggage on standard tickets. Always weigh your bag before going to the airport — overweight charges are 100–500 THB per kilogram and add up fast on multi-flight trips.

Thailand Packing List — What to Bring

A complete Thailand packing checklist that handles tropical heat, temple visits, monsoon downpours, and cooler northern evenings — without overpacking.

Quick Answer

What is the most important thing to pack for Thailand?

Light, breathable clothing; one modest outfit for temples; sturdy walking sandals; SPF 50+ sunscreen (hard to find locally); DEET mosquito repellent; a basic first-aid kit; printed copies of your documents; and a universal travel adapter. Pack lighter than you think — laundry is fast and cheap everywhere in Thailand.

Pack Light Principle

The single most useful Thailand packing rule is: pack less than you think you need. Laundry services exist on every other corner — 40–60 THB per kilo, returned same-day or next-day, washed-dried-folded. A two-week trip needs no more clothes than a four-day trip. Lightweight cotton and linen dry quickly even by handwash. The travellers who struggle with their luggage in Thailand are invariably the ones who packed for every possible scenario, not just the actual scenarios they will encounter.

Plan around 5–7 days of clothing for any trip length, plus one modest temple-appropriate outfit and one slightly smarter outfit for evenings out. Everything else can be bought cheaply if you discover you need it.

Buying Forgotten Items in Thailand

Toothpaste, soap, shampoo, sunscreen (limited high-SPF), mosquito repellent, painkillers, phone chargers, adapters, basic clothing, swimwear, sandals, and snorkel gear are all available at every 7-Eleven, Big C, Tesco Lotus, or local pharmacy at reasonable prices. Boots and Watsons pharmacies in Bangkok, Phuket, and Chiang Mai stock Western brands. Specialised items (technical hiking gear, prescription medication, specific contact lens solutions, modesty workout gear) are harder to find — pack these.
