Essential Documents
These go in your carry-on — never in checked luggage.
- Passport — Valid for at least 6 months beyond arrival date
- TDAC QR code — Save it on your phone. A printed copy is a useful backup, but printing is not required
- Return or onward flight ticket — Immigration may ask for proof
- Travel insurance documents — With emergency contact number
- Hotel booking confirmations — First night accommodation required for TDAC
- Visa documents (if applicable) — VOA, DTV, or non-immigrant visa paperwork
- Vaccination certificates — Yellow fever cert if arriving from endemic country
- Emergency contact card — Your country's embassy in Thailand
Clothing
Everyday Wear
- Lightweight cotton or linen shirts (5–7)
- Lightweight trousers or long skirts (2–3) — doubles as temple wear
- Shorts (3–4) — fine for beaches, markets, and restaurants
- Underwear and socks (7 pairs each)
- Comfortable walking sandals (e.g. Birkenstock, Teva)
- Light trainers for day trips
- Flip flops for beach and hostel showers
Temple & Modest Wear
Buddhist temples require covered shoulders and knees — for both men and women. Many major temples (Wat Phra Kaew, Doi Suthep) rent sarongs at the entrance, but it's better to pack your own.
- Lightweight scarf or pashmina (doubles as temple cover-up)
- Trousers that cover the knees
Swimwear & Beach
- Swimsuit or board shorts (2)
- Quick-dry towel — most hostels charge for towels
- UV-protective rash guard for snorkeling
Tropical Climate Essentials
- Reef-safe sunscreen SPF 50+ — Thailand bans non-reef-safe sunscreen in marine parks
- DEET insect repellent (30–50%) — Dengue risk in some areas — don't skip this
- Mosquito net — Essential for budget guesthouses or outdoor sleeping areas
- Lightweight rain poncho — Compact — takes up no space and is a lifesaver during a downpour
- Reusable water bottle with filter — Tap water is not drinkable; reduces plastic waste
- Hand sanitizer and wet wipes — Street food stalls rarely have soap
- Wide-brim hat or cap — Sun protection is non-negotiable April–June
- Sunglasses (UV400) — Glare from beaches and temples is intense
Tech & Electronics
- Universal travel adapter — Thailand runs on 220 volts. Sockets fit European-style plugs (Type C or F), and many also take flat two-pin US plugs. UK and Australian plugs need an adapter
- Portable power bank (20,000 mAh+) — Long travel days, tuk-tuks, and beach days drain batteries fast
- Waterproof phone case or pouch — Mandatory for boat trips, island hops, and Songkran
- Noise-cancelling headphones — Overnight trains and cheap guesthouses can be noisy
- Unlocked smartphone — For local SIM or eSIM
- Laptop or tablet (optional) — Coffee shop work culture is excellent in Bangkok and Chiang Mai
See our SIM Card vs eSIM guide for connectivity options.
Medical & Health
- Prescription medications — Bring a doctor's note with generic (non-brand) drug names and a letter explaining your condition
- Stomach medication — Imodium, rehydration salts, and Pepto-Bismol for traveler's diarrhea
- Antihistamines — Allergic reactions to tropical plants, shellfish, and insect bites
- Pain relief — Paracetamol and ibuprofen are cheap in Thailand, but bring a starter supply
- Antiseptic cream and plasters — Minor cuts can get infected quickly in tropical humidity
- Antifungal cream — Athlete's foot is common in wet, hot conditions
- Blister plasters — Sandals + heat + long walks = blisters
What NOT to Pack
The following items can result in fines, arrest, or confiscation at Thai customs:
- Vaping devices / e-cigarettes — Up to 10 years imprisonment and 30,000 THB fine
- Cannabis / CBD products — Recreational use is illegal in Thailand; medical use needs a valid Thai prescription. Do not bring any
- Recreational drugs — Severe penalties, including long prison sentences. They apply to tourists too
- More than 200 cigarettes (or 250 g of tobacco) or 1 litre of alcohol — These are the duty-free limits; declare anything above them at customs
- Buddha images for export — Some antique Buddha statues cannot be legally exported
See our Thailand Vaping Laws guide for full details on the e-cigarette ban.

- Passport and TDAC QR code

- 1–2 days of clothing change
- Valuables (camera, jewelry)
- Cash (some THB for arrival)
Safe in Checked Bag
- Clothing and shoes
- Sunscreen (over 100ml)
- Mosquito repellent
- Rain poncho
- Beach towel
- Adapter plugs
- Toiletries
Pack less: the laundry maths
The single change that improves most Thailand packing is bringing fewer clothes.
Laundry shops are everywhere and charge roughly 40 to 60 baht per kilogram, washed, dried and folded, usually returned the same day or the next. That is around a pound or a dollar for a full change of clothes.
Which means a two-week trip needs about five days of clothing, not fourteen. You will be hot, you will change more often than at home, and you will be doing laundry regardless — so the choice is between carrying two weeks of clothes and paying 60 baht.
The exceptions worth carrying properly: anything you cannot easily replace, anything you need on day one, and enough underwear that a delayed laundry is not a crisis.
What to buy there rather than pack
Thailand sells almost everything, often cheaper and always closer to where you need it.
| Buy in Thailand | Why |
|---|---|
| Umbrella and poncho | 7-Eleven, cheap, and you will buy one anyway |
| Toiletries and sunscreen | Widely available; leaves hold-luggage space |
| Beach clothes and shorts | Markets, a fraction of home prices |
| Flip-flops | Everywhere |
| Basic first aid | Pharmacies are excellent, cheap and unfussy |
| Bring from home | Why |
|---|---|
| Prescription medication | With the prescription, in original packaging |
| Reef-safe sunscreen, if you dive | The specific formulation is harder to find |
| Shoes, if your size is large | Thai sizing runs small |
| Contact lens solution in your brand | Availability varies |
| A high-factor sunscreen you trust | The rest is easy; this one is worth being sure about |
Pharmacies deserve a note of their own: Thai pharmacies dispense a great deal without prescription, staff often speak good English, and they are the sensible first stop for minor illness rather than a hospital.
The temple dress code, precisely
"Cover shoulders and knees" is the rule everyone quotes and it is not quite enough detail to avoid being turned away at the gate of the Grand Palace.
Both men and women. Men in vests or above-the-knee shorts are refused as readily as anyone else.
Shoulders covered means an actual sleeve, not a strappy top with a scarf draped over it — though a scarf will get you past most temples other than the strictest.
Knees covered means the hem reaches the knee when standing. Three-quarter trousers are fine; long shorts usually are not.
See-through does not count as covered. Nor do leggings at the strictest sites.
Shoes come off at the entrance to the building itself. Slip-ons are worth the trip on their own.
The Grand Palace and Wat Phra Kaew enforce this most strictly and rent cover-ups at the gate, at a queue and a price. A light long-sleeved shirt and a pair of loose trousers in your day bag solves it everywhere for the whole trip.
Packing for the trip you are actually taking
Islands and beaches. A dry bag, reef-safe sunscreen, a rash guard — the sun on the water is stronger than you think — and shoes you can walk over rocks in. Beach towels are usually provided; a quick-dry one is still useful.
Bangkok and cities. Air conditioning is aggressive, so a light layer for indoors is not optional. Walking shoes matter more than sandals; pavements are uneven.
The north, November to February. Genuinely cold at night in the hills — 10°C or lower is possible. A fleece and long trousers, which nobody expects to need in Thailand.
Any trip in rainy season. A poncho over an umbrella when you are on a motorbike or a boat, and a waterproof phone pouch.
The things people forget and regret
- A printed copy of your arrival card QR code, in your passport rather than a bag.
- A phone pouch that actually seals for boats and Songkran.
- A power bank, charged, since arrival days drain batteries.
- Plug adapters — sockets fit European-style round two-pin plugs, and many also take flat two-pin US plugs. UK and Australian plugs need an adapter.
- Enough cash for the immigration funds check, before you find the ATMs.
- A spare pair of glasses if you wear them; replacing them is possible but slow.
- Nothing on the prohibited list. Vapes above all, which are the single most common reason a trip starts at a customs desk. See the Thailand customs rules.
