What to pack for a trip to Thailande?
Most travellers arrive in Thailand expecting the heat, the temples and the street food — and still get caught out within the first 48 hours.
In short, what catches you out here
- Payments in Thailand are almost entirely cash-based; many street vendors, tuk-tuks, local guesthouses and island ferry operators do not accept cards, leaving visitors stranded without baht.
- Temples across Thailand (Wat Pho, Doi Suthep, Grand Palace, etc.) strictly enforce dress codes: exposed shoulders or knees result in denied entry or forced purchase of overpriced wraps at the gate.
- Bangkok and southern Thailand combine 35 °C+ heat with very high humidity year-round, causing rapid exhaustion, sweat-soaked clothes, and chafing on long sightseeing days.
Why this list?
The Grand Palace turns them away for wearing shorts. A monsoon downpour drenches their bag during a longtail boat crossing. Their phone dies mid-afternoon because Grab, Maps and the camera ran simultaneously all day. They discover that the island ferry, the market lunch and the temple donation box all require cash they don't have. Thailand rewards the prepared traveller generously: distances are vast, climates shift dramatically between north and south, and the gap between a smooth trip and a frustrating one often comes down to a sarong, a dry bag and a padlock. This list focuses on what experienced Thailand travellers wish they had packed — not the sunscreen (you know), but the anti-chafing balm, the permethrin spray and the offline maps downloaded before the mountain road swallowed the signal.
When to go
The dry season from November to March brings clear skies and manageable heat; the monsoon from May to October brings heavy rains and localised flooding.
Less favourable : May to October
✔To do before you leave
Your countdown: every action at the right time, from furthest ahead to departure day.
- Visa rules change frequently and vary by nationality; arriving at the airport without the correct authorisation or with a passport valid for less than 6 months risks being denied boarding.
- Mobile data is patchy on mountain roads in Chiang Mai province and on smaller islands; having offline maps prevents being stranded without navigation when your SIM loses signal.
- Grab is the standard alternative to negotiating tuk-tuk and taxi fares in Bangkok and major cities; setting it up before arrival (including card payment) avoids being overcharged on arrival when tired.
- Street food stalls, tuk-tuks, local ferries and many guesthouses are cash-only; running out of baht in a remote area or on an island can leave you without food, transport or accommodation.
- Passports left at guesthouses as deposit (common practice), lost on boats or stolen at markets are a real risk; cloud-stored photos of passport, travel insurance, and e-visa confirmation speed up consular assistance dramatically.
✔The essentials
Without these, the trip is compromised. Don't forget them.
- Temples refuse entry to visitors with bare shoulders or knees regardless of the heat; a thin cotton sarong covers both issues, doubles as a towel on beaches and costs nothing to pack.
- Dengue-carrying mosquitoes are active throughout the day in jungle and coastal areas, not just at dusk; local repellents are weaker and harder to find outside tourist centres.
- Thailand uses multiple socket types (A, B, C) at 220 V; guesthouses often have only one or two sockets shared between several devices across a long trip.
- Medical care at private hospitals (the only reliable option) requires proof of insurance upfront; without it, large deposits are demanded before treatment, which can be thousands of pounds.
✔Nice-to-haves
Not vital, but noticeably more comfortable with them.
- For treks in northern Thailand or jungle areas where mosquito exposure is prolonged and unavoidable, treating clothes with permethrin adds a critical layer of protection beyond spray alone.
- Shoes must be removed at every temple entrance and at many traditional guesthouses, sometimes ten times in a single day; lace-up shoes become a genuine source of frustration and delay.
- Island boat transfers, longtail boats and monsoon rain can soak a regular backpack completely; a dry bag protects passport, phone and cash during water crossings and downpours.
- A single breathable long-sleeve shirt solves temple dress codes, sun protection and mosquito exposure simultaneously, without adding meaningful weight — travellers who pack only T-shirts constantly improvise.
- Street food and tap water changes frequently cause traveller's diarrhoea and dehydration; ORS sachets restore electrolytes rapidly and are far more effective than plain water when ill in the heat.
- Tap water is unsafe for drinking throughout Thailand, including in rural guesthouses; tablets or a UV pen eliminate the need to buy dozens of single-use plastic bottles over a long stay.
- Backpacker guesthouses and overnight bus luggage holds routinely use hasps without locks; a small padlock on your bag zip is the simplest deterrent against opportunistic tampering.
- Home roaming is expensive and unreliable between northern mountains, Bangkok and southern islands; a local SIM with data is essential for navigation, Grab (the local ride-hailing app) and ferry timetables.
- Many budget guesthouses and beach bungalows do not provide towels or charge extra for them; a microfibre towel dries in minutes in humid heat and takes up almost no space.
- Running Google Maps, Grab, translation apps and the camera simultaneously drains a phone battery well before a full day of sightseeing ends; charging points are scarce on long bus or boat journeys.
✔Weather & season
Adjust to the time of year and forecast for your trip.
- Walking 15–20 km per day in Bangkok or at beach resorts in 35 °C heat and 90 % humidity causes severe inner-thigh chafing within hours; this is one of the most common complaints travellers don't anticipate.
- Tropical downpours in the rainy season arrive without warning and last up to 90 minutes; a compact umbrella is far more useful than a poncho when moving between market stalls or temples.
- Reflected sunlight off white sand and water on island days is far more intense than it appears; local brands are expensive in resort shops, and hours in the water wash off standard cream rapidly.

✔ Good to know
- Make sure your passport is valid for at least 6 months from the date you plan to enter Thailand — airlines typically check this at check-in, and immigration officers verify it again on arrival. source
- Complete the Thailand Digital Arrival Card (TDAC) online before you fly — the window opens 72 hours before arrival and closes at departure. It's free; any site asking for a fee is unofficial. source
- Keep Thai baht cash handy — street food stalls, local markets, boats, tuk-tuks, and small massage shops rarely accept cards. ATMs are plentiful at airports and shopping malls, and exchanging money on arrival is easy. source
- Pack a universal travel adapter: Thai sockets come in several types (A, B, C and O) at 220 V / 50 Hz. Most modern chargers are dual-voltage and won't need a voltage converter, but an adapter plug is still helpful. source
- Pack at least one outfit that covers shoulders and knees — temples across Thailand ask visitors to dress modestly, and stricter sites like Wat Phra Kaew in Bangkok can turn you away without the right clothing. Slip-on shoes are also a practical choice since you'll remove them at every temple entrance. source
- Check in with a travel health clinic before departure: hepatitis A and hepatitis B vaccinations are strongly recommended by the CDC, and depending on your itinerary (rural areas, outdoor activities), a doctor may also suggest typhoid or Japanese encephalitis vaccines. source
- Sleeveless tops or short shorts (as your only outfit) — Packing clothing that leaves shoulders or knees uncovered as your sole option could see you turned away at temples — keep at least one modest layer in your bag.
- Large hard-shell roll-on suitcase for island hopping — Ferries, longtail boats, and guesthouses on smaller islands often have very limited luggage handling — a soft bag or backpack tends to be far easier to manage.
- Foreign currency (USD, EUR, etc.) for everyday spending — Foreign notes are generally not accepted for daily purchases at markets, street stalls, or transport — plan to exchange money or withdraw baht on arrival rather than counting on foreign currency being taken.
✔ Frequently asked questions
Is tap water safe to drink in Thailand?
Tap water in Thailand is generally not recommended for drinking by visitors, even in Bangkok, as distribution infrastructure varies across the country. Bottled or filtered water is the standard approach; affordable drinking water is available at every 7-Eleven and local grocery store, and many hotels provide a carafe or dispenser. Bring a reusable bottle you can refill from safe sources to cut down on single-use plastic.
How do I get around Thailand once I arrive?
Bangkok has an extensive public network combining the BTS Skytrain, MRT metro and river ferries; a rechargeable card simplifies daily travel. For flexible city trips, the Grab app offers fixed-price rides throughout the country — a handy alternative to negotiating with tuk-tuks or taxis (always check the meter is running). Inter-city travel options include budget domestic flights, long-distance buses and trains; on southern islands and in Chiang Mai, shared songthaews and scooter rentals are common, so budget some flexibility for getting between places.
What should I pack for Thailand depending on the season?
Lightweight, breathable clothing (cotton or linen) works year-round given the tropical climate. The rainy season runs roughly May to October across most of the country, so a compact poncho or light rain jacket and grippy sandals are worth packing for that period. For temple visits — and there will be many — shoulders and knees need to be covered, so a sarong or light trousers and a sleeved top save you from renting cover-ups at the gate. Ubiquitous air conditioning in transport and restaurants can feel surprisingly cold, so one light layer in your bag is genuinely useful.
