Things to do in Thailand: 34 experiences worth the trip

Updated Leer en español

Thailand puts royal Bangkok, the ruined capitals of Ayutthaya and Sukhothai, the Lanna temples and hills of Chiang Mai and Chiang Rai, and two very different coasts into one trip. This list runs from the Grand Palace and Chinatown's night food to rescued elephants, national park waterfalls, the Andaman islands of Krabi and Phang Nga and the Gulf islands of Koh Phangan and Koh Tao, and each entry says which gate, which pier, which season and which booking actually matter.

The two coasts have opposite weather. The Andaman side (Krabi, Phuket, Phi Phi, the Similans) is at its calmest from roughly November to April, the Similan Islands close from mid May to mid October, and Maya Bay shuts every August and September. The Gulf islands get their main rains from about November to February. Pick the coast to match your dates.

Since 15 September 2026, Spanish passport holders get 30 days without a visa instead of 60, and every foreign arrival must file the Thailand Digital Arrival Card in the three days before landing.

Plan your trip

  • When to go

    The cool, dry season from November to February is the most popular time and the most expensive around Christmas, New Year and Chinese New Year. March and April are the hottest months, with temperatures near 40°C. The rains run from May to October and are heaviest from September, except on the Gulf islands (Koh Samui, Koh Phangan, Koh Tao), where the wet season is roughly November to February. Seasonal closures to plan around: the Similan Islands open only from 15 October to 15 May, Maya Bay closes from 1 August to 30 September, Doi Inthanon's Kew Mae Pan trail closes from June to October, and Ang Thong Marine Park usually closes from 1 November to 15 December.

  • How many days

    Two weeks covers three regions without rushing: three or four days in Bangkok with a day trip to Ayutthaya or Kanchanaburi, four or five days in Chiang Mai and Chiang Rai, and five or six days on one coast. With ten days, pair Bangkok with either the north or one coast rather than squeezing in all three. Sukhothai deserves a night of its own, as it is about an hour by bus from Phitsanulok station.

  • Getting around

    Long-distance trains leave from Bangkok's Krung Thep Aphiwat Central station, which replaced Hua Lamphong for these services in January 2023; book sleepers on the State Railway's D-Ticket site. Joint train and ferry tickets take you from Bangkok to Koh Samui, Koh Phangan and Koh Tao via Surat Thani. In Bangkok, the BTS Skytrain, the MRT metro and the orange-flag Chao Phraya Express Boat avoid the traffic: Saphan Taksin to Tha Chang, by the Grand Palace, is about 30 minutes by boat. In the north and on the islands, hire a driver, a songthaew or a scooter only if you hold a licence that your insurance accepts.

  • Entry rules

    According to Spain's foreign ministry (page updated 3 September 2026), Spanish citizens need no visa for tourism, but since 15 September 2026 the maximum visa-free stay is 30 days, extendable once by 30 days at an immigration office. Your passport must be valid for at least six months. All foreign arrivals by air, sea or land must complete the Thailand Digital Arrival Card online in the three days before arrival. Thailand cut its visa-exemption list from 93 to 60 countries on the same date, so travellers with other passports should check the current list with the Thai Ministry of Foreign Affairs.

  • Money and payments

    The currency is the Thai baht. Carry cash for national park gates, temple tickets, long-tails and market stalls: rural parks rarely take cards. Published foreign adult fees include 300 baht for Erawan and Doi Inthanon national parks, 500 baht for the Similan Islands, 500 baht for the Grand Palace, 300 baht for Wat Pho and 200 baht for the White Temple. Thai nationals pay much less, which is normal and legal.

Questions travellers ask

Do Spanish citizens need a visa for Thailand?

No, not for tourism. Since 15 September 2026 the visa-free stay is 30 days, down from 60, and it can be extended once by 30 days at an immigration office. Your passport needs at least six months of validity, and you must file the Thailand Digital Arrival Card in the three days before you arrive.

What is the Thailand Digital Arrival Card (TDAC)?

It is the online arrival form that replaced the paper card. Every foreign visitor arriving by air, sea or land must complete it in the three days before arrival, whatever the reason for the trip. Use the official immigration site, tdac.immigration.go.th, and avoid look-alike sites that charge for it.

Can you swim at Maya Bay?

No. Since the bay reopened in 2022, swimming is banned and wading stops at knee depth, to protect a blacktip reef shark nursery and replanted coral. Boats moor at Loh Samah Bay and you walk in on a boardwalk, and the bay closes every year from 1 August to 30 September.

What should I wear to the Grand Palace in Bangkok?

Cover your shoulders and legs. The palace refuses sleeveless tops, see-through or cropped tops, shorts, mini skirts and torn, tight or cycling trousers. The same standard works for Wat Pho, Wat Arun and the temples of Chiang Mai and Chiang Rai.

When is Yi Peng in Chiang Mai in 2026?

Yi Peng falls on the full moon of the twelfth lunar month, together with Loy Krathong; in 2026 that is around 24 November, with celebrations over about three days. Sky lanterns may only be released at set times and places, and the big mass releases are separate organised events, so check the official programme before booking.

Which Thai coast is better in December?

The Andaman coast: Krabi, Phuket, Phi Phi and the Similan Islands are in their dry, calm season. The Gulf islands of Koh Samui, Koh Phangan and Koh Tao are in their wettest months from about November to February, and Ang Thong Marine Park usually stays closed until 15 December.
