The Best Beaches in Thailand: Where to Go by Coast and Season

The best beaches in Thailand depend on the coast and the month. The Andaman side (Phuket, Krabi, Koh Lanta) is at its best from November to April, while Koh Samui, Koh Phangan and Koh Tao in the Gulf of Thailand are the pick for June to September. Hua Hin and Koh Samet are the easy options when you're starting from Bangkok and don't want a flight.

Thailand beaches range from party strips to lagoons you share with a handful of other people. This guide sorts them by coast, season and the kind of stay you want, so you can pick one beach instead of scrolling through fifteen.

Which part of Thailand is best for beaches?

The Andaman coast is best from November to April; the Gulf islands of Samui, Phangan and Tao suit June to September. Beaches near Bangkok suit a short stay.

The Andaman Sea gives you the postcard Thailand: limestone karst rising out of green water, long boat days around Phi Phi, cliffs at Railay. It's the better coast for scenery, and its dry season is the main season for the whole country. The Gulf of Thailand side is gentler and, around Samui, stays drier while the Andaman monsoon blows through. Beaches within reach of Bangkok are the practical third option, with no domestic flight and no long transfer.

For a month-by-month view of the weather across the whole country, read our guide to the best time to visit Thailand.

How to choose your beach in Thailand

Four questions settle most of it.

• Weather and season. Most beaches are at their best from November to April, in the dry season, with mild weather and calm water. If your dates fall in summer, when the monsoon affects the Andaman, head for the Samui islands: Koh Samui, Koh Phangan and Koh Tao.
• Budget. The beach stop can take a sizeable share of a trip's budget, mostly through flights and transfers. To keep it down, pick a beach you can reach from Bangkok without a domestic flight, such as Hua Hin or Koh Samet.
• Time on site. On a short stay, a beach close to the capital saves long transfers. Hua Hin, Koh Samet and the Trat islands are the ones to look at.
• Atmosphere. Some beaches are lively and built around nightlife; others are made for doing nothing. Thailand covers both ends, from the party-loving backpacker to the honeymoon couple, so decide which you are before you pick a coast.

Best beaches on the Andaman coast (November to April)

The Andaman side is the better-known coast, and it has the widest spread of beaches, from loud to nearly empty. Every beach below suits the dry season; the monsoon affects this side in summer.

Phuket

Phuket is the undisputed star of the Andaman, and its beaches differ more than people expect.

• Patong is for nightlife: jet skis, parasailing, markets and entertainment. It is very busy, which is either the point or the problem.
• Karon and Kata are less crowded, and at certain times of year they're good for surfing.
• Day excursions run to the Phi Phi islands, Phang Nga Bay and Koh Pu, all known for snorkelling.

If you want a quiet beach, Phuket's west coast isn't where to look first. Use it as a base for boat days, then go further for calm.

Krabi and Railay

Krabi is known for karst landscapes and good-category accommodation. It's the starting point for Railay Beach, a beach surrounded by cliffs and much appreciated for climbing and swimming. From Krabi you can also take excursions to the islands of Poda, Gai, Tup and Mawr, and to Phanom Bencha National Park, where nature takes over from the beach scene.

Koh Phi Phi and Maya Bay

Maya Bay reopened on 1 October 2026 after its annual closure (1 August to 30 September). It is open from 07:00 to 18:00, weather permitting. The national park fee is 200 THB for adults and 100 THB for children aged 3 to 14, as of November 2026, according to the official national parks site.

At the rate of 12 November 2026 (1 THB = 0.029573 USD, Frankfurter), that is about US$6 for an adult and US$3 for a child.

Plan around the closure rather than against it. The park shuts every year for the same two months, so a trip that includes Maya Bay should avoid August and September. Check the park's current notices before you book boats, since dates can change.

Koh Phi Phi itself is also a popular base for snorkelling, which is why it turns up again further down this page.

Quieter islands: Koh Lanta, Koh Yao Noi, Koh Yao Yai and Koh Lipe

Reached from Phuket or Krabi, these islands offer white-sand beaches and a few disconnected nights. Local atmosphere and few crowds are the draw, even though tourism is slowly developing.

• Koh Lanta suits families looking for calm; Klong Dao is the beach to know.
• Koh Yao Noi and Koh Yao Yai suit couples looking for privacy, sunsets and turquoise lagoons.
• Koh Lipe has Sunset Beach, a small-bay choice for couples.

Best beaches in the Gulf of Thailand (June to September on Samui)

The Samui archipelago is the answer for a summer trip. Between June and September it enjoys a drier microclimate while the monsoon affects the Andaman, so these islands cover the months when the other coast is at its weakest. For the wider picture, the best time to visit Thailand guide covers the rest of the country.

Koh Samui

Koh Samui offers great diversity, in accommodation, beaches and activities. Chaweng and Lamai are charming coves, and Bophut has a more upscale atmosphere. Lamai also works well for families, with its facilities and gentle slope.

Koh Phangan and Koh Tao

Koh Phangan is very well known for its Full Moon parties in the south. The rest of the island stays peaceful, with beautiful wild beaches in the north and east, so the party reputation covers only part of it.

Koh Tao is a prime spot for scuba diving and snorkelling thanks to its coral reefs. The mood is relaxed and backpacker-friendly.

Beaches close to Bangkok

Koh Samet is in Rayong province, a road trip plus a short ferry from Bangkok. That is the whole logistics argument for this group of beaches: you skip the domestic flight and keep the transfers short.

• Hua Hin has a long ribbon of golden sand lined with family resorts and a well-known night market. The atmosphere is peaceful and built around relaxing. There is little snorkelling and few water activities, which is why it suits small budgets and express stays.
• Koh Samet is livelier and has pretty seabeds for snorkelling. For couples, Ao Prao is the quieter option.
• Koh Chang sits in the Trat archipelago and is a compromise between accessibility, a lively atmosphere and good snorkelling. It also has more secret, quiet beaches, especially in the south of the island.
• Koh Kut (also written Koh Kood) is the dream beach for a romantic stay or a honeymoon: white sand, coconut palms, a preserved atmosphere and crystal-clear lagoons. Accommodation costs more here than on the other islands in this group.

Best beaches by traveller type

Names first, then the reason they fit.

• Families: calm, long beaches with a gentle slope. Klong Dao on Koh Lanta and Lamai on Koh Samui are the usual choices, with suitable facilities nearby.
• Couples: more secluded coves and small bays. Ao Prao on Koh Samet, Sunset Beach on Koh Lipe and the south beaches of Koh Yao Noi bring privacy and romantic scenery.
• Snorkelling and diving: the waters around Koh Tao, Koh Phi Phi and Phang Nga Bay, plus the reefs on the north side of some beaches, for the quality of marine life.
• Nightlife: Patong in Phuket or the south coast of Koh Phangan, while staying vigilant about night-time crowds.
