Thailand is safe to visit, with no major travel advisories, but avoid parts of the south near the Thailand-Malaysia border and areas close to the Cambodia border.
The cool dry season begins. November is dry and pleasant, with clearer skies and lower humidity; crowds grow into December and January high season. Festivals like Yi Peng & Loy Krathong light up Chiang Mai, so book early.
Thailand is the easiest big trip in Asia: cheap, warm, well connected and used to visitors, with temples and street food in Bangkok, mountains and night markets around Chiang Mai and two coasts of islands. This page covers what you need to know before the first trip, in the order you will need it. The topic guides linked at the bottom go deeper.
Why Visit Thailand?#
Thailand does a little of everything and does it cheaply: one two-week trip can hold a gilded royal palace, a cooking class in the mountains and a longtail boat to a limestone island. These are the things that bring more than 30 million visitors a year.
Islands and beaches. Two coasts and hundreds of islands, from the limestone cliffs of Railay and the Phi Phi Islands to the palm-lined Gulf islands of Ko Samui and Ko Tao. One coast or the other is dry almost all year.
Food that people fly for. Street stalls in Bangkok, khao soi in Chiang Mai, fiery southern curries, and a night market in every town. A great meal often costs under $3.
World-famous nightlife. Rooftop bars over Bangkok, the Full Moon Party on Ko Pha-ngan, and beach bars with fire shows from Phuket to Ko Lipe.
Temples and history. Gilded temples like Wat Pho in Bangkok, the ruined royal capitals of Ayutthaya and Sukhothai, and more than 300 temples in and around Chiang Mai.
Mountains and jungle. Misty hills, hill-tribe villages and elephant sanctuaries in the north, and floating bungalows on the lake in Khao Sok.
Easy and great value. Cheap flights, sleeper trains and ferries link everything, rooms start around $15, and the tourist trail is well worn enough that a first solo trip is easy.
Things to Watch Out For#
Motorbikes. Scooter crashes are the most common way visitors get hurt, and insurance won’t pay without a motorbike licence and a helmet.
Tourist scams. Ignore anyone who says the Grand Palace is closed today, skip 20-baht tuk-tuk tours, and use Grab or a metered taxi.
Rip currents. From May to October, Andaman beaches like Patong and Kata drown swimmers every year. Never swim at a red flag.
Dengue. There is no pill for it, so use DEET or picaridin repellent, especially at dawn and dusk.
Strict laws. Criticising the royal family, vaping and drugs can all mean jail.

Who Is Thailand For?#
Foodies
Bangkok street food, khao soi in the north, fiery southern curries and a night market in every town.
Beach lovers
Limestone cliffs on the Andaman, palm-lined Gulf islands, and a dry season on one coast or the other almost all year.
Culture seekers
Backpackers
Khao San Road, cheap guesthouses, sleeper trains and a well-worn route that makes a first solo trip easy.
Families
Couples
Quiet islands, boutique resorts, sunset dinners on the sand and cool mountain lodges in the north.
Nightlife
Rooftop bars in Bangkok, the Full Moon Party on Ko Pha-ngan and beach bars everywhere in between.
What you need to get in#
Most first-timers do not need a visa. Since 15 September 2026, passports from 60 countries, including the US, UK, Canada, Australia, New Zealand and the EU, get 30 days visa-free on arrival, for tourism only. That was 60 days until this September, so ignore older advice.
Passport
Valid for at least six months from the day you arrive, with a blank page.
Arrival card (TDAC)
Free and online, filed within three days before you land at tdac.immigration.go.th. Sites that charge for it are scams.
Proof on request
An onward or return ticket and 10,000 baht per person in funds. Rarely asked at airports, but you can be refused without them.
Want longer than 30 days? Extend once for 30 more at an immigration office (1,900 baht), or apply before you fly for the 60-day tourist e-visa. There are no compulsory vaccinations unless you arrive from a yellow fever country; routine shots plus hepatitis A and typhoid are the usual advice. Buy travel insurance, and make sure it covers motorbikes if you plan to ride one. The full rules are in the Thailand visa guide.
When to go#
The short answer is November to February: cool by Thai standards, dry almost everywhere and the busiest, priciest months. The two coasts have opposite rainy seasons, so there is always a beach in good weather somewhere.
| Months | What it is like | Good to know |
|---|---|---|
| November to February | Cool and dry, highs around 30-33°C | Best weather, biggest crowds; book rooms and sleeper trains early, especially at Christmas and New Year |
| March to May | Hot season, 35-40°C in Bangkok and Isaan | Songkran water fights mid-April; burning-season haze in the north from mid-February to mid-April |
| June to October | Rainy season, mostly afternoon storms | Cheaper and green; Ko Samui, Ko Pha-ngan and Ko Tao are the dry side in June to August |
The catch is the Gulf islands, which are wettest from October to December. More detail, month by month, is in the best time to visit Thailand.
The classic trips and what they cost#
Almost every first trip has the same shape: Bangkok, then the north around Chiang Mai, then one island coast. The overnight train or a one-hour flight links the first two, and a direct flight takes you from the north to the beach.
Prices are per person, with two sharing mid-range rooms, and don’t include international flights.
| Trip | Route | Typical cost |
|---|---|---|
| 7 days | Bangkok (2 nights), sleeper train to Chiang Mai (2), fly to Krabi or Ko Samui (3) | 20,000-40,000 THB ($600-1,200) |
| 10 days | Adds Chiang Rai and a second island: Phuket, Phi Phi, Railay | 30,000-55,000 THB ($900-1,650) |
| 14 days | Adds Ayutthaya, Sukhothai and Pai, then the Andaman islands | 40,000-80,000 THB ($1,200-2,400) |
| 10 days, beaches only | Phuket, Phi Phi, Railay, Ko Lanta, Ko Lipe | 35,000-60,000 THB ($1,050-1,800) |
Day to day, backpackers get by on 1,000-1,500 baht ($30-45), a mid-range trip runs 1,700-3,300 baht ($50-100) and resort travel starts around 5,000 baht ($150). Islands cost 30-50% more than the mainland. Day-by-day plans are in the Thailand itineraries and real prices in Thailand travel costs.
With 10 days, do the 7-day route slowly rather than adding a fourth stop. Three nights is about where a place stops feeling like a transit stop.
Thailand in a nutshell#
- Capital: Bangkok, called Krung Thep by Thais. Almost every first trip starts at Suvarnabhumi or Don Mueang airport.
- People: about 66 million, mostly Theravada Buddhist. A constitutional monarchy, and the only country in Southeast Asia never colonised by a European power. More in Thailand demographics.
- Language: Thai. English is common in hotels, transport and tourist areas, much less in the countryside and Isaan.
- Money: Thai baht (THB), roughly 33.5 to the US dollar. Cards work in cities; islands and markets run on cash.
- Daily budget: $30-45 backpacking, $50-100 mid-range, $150 and up for resorts. Real prices in Thailand travel costs.
- Electricity: 220V, 50Hz. Sockets take both flat US and round European two-pin plugs; see Thailand plug types.
- Time: UTC+7 all year, no daylight saving.
- Driving: on the left. Most visitors use Grab, trains, buses and budget flights instead.
- Emergencies: 191 police, 1669 ambulance, 1155 tourist police (English spoken). More on the Thailand emergency page.
Don't forget to bring#
Temple clothes
Something that covers shoulders and knees. The Grand Palace turns away shorts and vest tops, and so do many temples.
A low-fee bank card
Thai ATMs charge 220 baht per withdrawal on foreign cards, so take out large amounts and carry a backup card.
An unlocked phone
A tourist SIM costs about 299 baht for 8 days at the airport, or use an eSIM. You’ll need data for Grab and maps.
Reef-safe sunscreen
Sunscreen costs more in Thailand than at home, and some marine parks ban the reef-damaging kinds.
Repellent and a light rain jacket
DEET or picaridin for the mosquitoes (dengue is around all year), and a shell for the June to October storms.
A warm layer
For freezing air-conditioned buses and trains, and for chilly December nights in the northern mountains.
Leave behind vapes and e-cigarettes, which are illegal to bring in or use, with real fines and arrests. Cannabis is again restricted to medical prescriptions, despite the shops you will still see.
Good to know before you land#
- Temple manners: shoes off before entering a temple or a home, never point your feet at a Buddha image or a person, and don’t touch anyone’s head. Women should not touch monks or hand things to them directly.
- Getting around: the BTS Skytrain and MRT in Bangkok, Grab for taxis, sleeper trains and budget flights between regions, and combined bus-and-boat tickets to the islands. Our getting around guide covers each one.
- Food and water: street food is generally safe and often the best food in town. Drink bottled or filtered water, which is everywhere and cheap.
- Elephants: choose a no-riding sanctuary such as Elephant Nature Park, and book ahead in high season.

First time in Thailand FAQs#
Is Thailand good for a first trip to Asia?
Yes. It is probably the easiest country in Asia for a first visit: tourism is well organised, English is common in tourist areas, transport is cheap and frequent, and prices are low. The classic Bangkok, Chiang Mai and islands route is easy to do on your own.
How many days do I need in Thailand?
Ten days to two weeks is the sweet spot for a first trip, enough for Bangkok, the north and one island coast at a relaxed pace. A week works if you choose just two areas.
How much money do I need for two weeks in Thailand?
About 40,000-80,000 baht ($1,200-2,400) per person on a mid-range budget, not counting international flights. Backpackers can spend half that.
Do I need a visa for Thailand?
Most Western passports get 30 days visa-free on arrival (since 15 September 2026). Everyone must file the free TDAC arrival card online in the three days before arrival. Check your own nationality on the official Thai e-Visa portal.
What should I avoid doing in Thailand?
Don’t criticise the royal family, don’t bring vapes, don’t ride a motorbike without a licence and a helmet, and don’t touch heads or point your feet at people or Buddha images. Avoid elephant riding and anyone who says a big sight is closed today.
