Thailand travel guide for first-time visitors

Thailand is one of the easiest countries in Asia for a first visit: many nationalities can enter without a visa for up to 30 days, Bangkok is a major flight hub, and a well-planned 10-night trip can combine temples, food, mountains and beaches. The essentials are to register the free Thailand Digital Arrival Card before you fly, dress modestly at temples, carry some Thai baht and choose your coast to suit the season.

Who Thailand suits

Thailand works for almost every kind of traveller. Couples and honeymooners head for the Andaman islands; families appreciate short transfers, good-value hotels and gentle beaches; food lovers come for street markets and cooking classes; and culture seekers can spend days among royal palaces and ancient capitals such as Ayutthaya Historical Park and Sukhothai. It is also an easy place to slow down, with spa and wellness retreats on most islands.

Entry and visa overview

Entry rules depend on your nationality, so always check before booking. As of November 2026, the main points are:

• Visa exemption: from 15 September 2026, nationals of 60 countries and territories, including the UK, US, Australia, Japan and Singapore, can stay up to 30 days for tourism without a visa, according to the Tourism Authority of Thailand. Some nationalities have different bilateral arrangements of 14, 30 or 90 days.
• Thailand Digital Arrival Card: all foreign nationals must complete the free TDAC online, within the 3 days before arrival, on the official TDAC portal.
• Passport: the UK government advises at least 6 months' validity on arrival and one blank page.
• Onward travel and funds: immigration may ask for proof of a return or onward ticket and to see at least THB 10,000 per person.

Gateway airports

Most long-haul visitors arrive in Bangkok at Suvarnabhumi Airport (BKK), with Don Mueang (DMK) handling many low-cost and domestic flights. Phuket (HKT) has direct international flights and is the gateway to the Andaman coast, while Chiang Mai (CNX), Krabi (KBV) and Koh Samui (USM) are short domestic hops from Bangkok. Flying into Bangkok and out of Phuket avoids backtracking.

Money, language, power and time

Getting around

• Domestic flights are the quickest way to cover long distances, such as Bangkok to Chiang Mai or Phuket.
• Trains and private transfers suit shorter hops, such as Bangkok to Ayutthaya or Hua Hin.
• In Bangkok, the elevated and underground rail lines avoid traffic; river boats are a pleasant way to reach the riverside temples.
• Island boats connect Phuket, Krabi and the Phi Phi Islands; the UK government warns that standards vary and seas can be rough in monsoon season, so use reputable operators.
• Think twice before hiring a scooter: the UK government notes Thailand has one of the world's highest motorcycle death rates, helmets are compulsory and you need the right licence and an International Driving Permit for your insurance to be valid.

Suggested routes by trip length

In the north, base yourself in Chiang Mai to see the old city's temples and make day trips to Doi Inthanon or the White Temple in Chiang Rai. Between October and January, consider swapping the Andaman coast for the Gulf only if your dates suit: our month-by-month weather guide explains why.

Etiquette and culture

• Dress modestly at temples and royal sites, covering shoulders and knees, and remove your shoes before entering temple buildings.
• Show respect for the monarchy; criticism of the royal family is a serious offence under Thai law.
• The head is considered sacred and the feet the lowest part of the body, so avoid touching people's heads or pointing your feet at people or Buddha images.
• A wai, palms pressed together with a slight bow, is the traditional greeting; a smile and a polite tone go a long way.
• Women should not touch monks or hand items directly to them.

Health and safety

Check vaccination advice with your doctor or a travel clinic at least 8 weeks before you go. The UK government lists dengue, malaria, Zika and rabies among the health risks in Thailand and advises comprehensive travel insurance, because hospitals require a guarantee of payment before treatment. Use mosquito repellent, swim only where lifeguard flags allow, and be aware that jellyfish, whose stings can be dangerous, can come close to shore between May and October.

Common scams include over-priced tours, jet-ski operators claiming damage, and card skimming. Never leave your passport as a deposit with rental businesses. The UK government also advises against all but essential travel to the four southernmost provinces bordering Malaysia; the main tourist areas are unaffected. Read the full UK travel advice for Thailand or your own government's equivalent before you travel.

Practical tips for a smooth first trip

• Keep a printed or saved copy of your TDAC confirmation and return ticket for immigration.
• Budget a little extra time for the Grand Palace: arrive early, as tickets are sold until mid-afternoon.
• Plan rest time in the heat, especially from March to May.
• Note that it is illegal to take cannabis out of Thailand, even though it is sold locally.
• Read our guide to Thailand trip costs before setting your budget.
