12 Best Beaches in Thailand: Where to Go in 2027?

The best beaches in Thailand are Railay and Phra Nang in Krabi, Maya Bay on Koh Phi Phi, Donald Duck Bay in the Similan Islands, Sairee Beach on Koh Tao and Sai Kaew on Koh Samet, the closest island beach to Bangkok. Timing matters more than the beach itself: the Andaman coast (Phuket, Krabi) is best from November to April, while the Gulf islands (Koh Samui, Koh Phangan, Koh Tao) are best from February to August. This guide ranks 12 beaches by coast, with the scenery, atmosphere, best months and an honest downside for each, plus top picks for families, couples and swimmers.

Andaman Coast vs Gulf of Thailand: Which Coast Suits You?

Thailand has 2 coastlines with opposite rainy seasons and quite different personalities. The Andaman Sea on the west is famous for limestone cliffs and island-hopping; the Gulf of Thailand on the east is softer and more resort-style, with the best diving for beginners. Compare them before you book:

If your dates fall between May and October, choose the Gulf islands; between November and April, the Andaman coast is at its best, and January to April works on both.

12 Best Beaches in Thailand by Coast

The numbers follow the map from the Andaman Sea to the Gulf, not a strict ranking, so you can pick the best beach for the coast you are visiting.

Best Beaches on the Andaman Coast

1. Railay West (Krabi) – Limestone Cliffs and Sunset Swims

Railay West in Krabi, reachable only by boat, where sheer limestone cliffs frame one of Thailand’s finest sunset swimming beaches.

Railay sits on a peninsula cut off from the mainland by towering limestone cliffs, so the only way in is by boat, and there are no roads or cars. Railay West is its showpiece: a curve of soft sand framed by vertical rock walls, with calm, warm water in season and the best sunsets in Krabi.

Days here are about swimming, kayaking to the nearby islands and watching climbers on the cliffs; Railay is one of the world’s best-known rock-climbing destinations, and beginners can join half-day courses. In the evening, once the day boats leave, the peninsula becomes a quiet village of bars and seafood restaurants.

• Best for: couples, climbers and anyone who wants a beach with no roads
• Getting there: a 15-minute long-tail boat ride from Ao Nang beach
• Where to stay: on Railay itself for quiet evenings after the day boats leave, or in Ao Nang for more choice
• Where to eat: the beachfront restaurants on Railay West for sunset dinners, or the cheaper bars on Railay East
• Best months: November to April
• Honest downside: it is busy with day trippers from late morning; Railay East, a short walk away, is muddy at low tide and not for swimming

>>> Make a trip of it: our Phuket and Krabi tour spends 10 days between the 2 provinces, with time for Railay and the islands. From $770 per person.

2. Phra Nang Cave Beach (Krabi) – A Shrine in the Cliffs

Phra Nang Cave Beach in Krabi, framed by limestone overhangs and home to the Princess Cave shrine honoured by local fishermen.

A 10-minute walk from Railay East along a cliff-side path, Phra Nang is many people’s favourite beach in Thailand. Limestone islands rise straight out of the turquoise sea, and the cliffs at the back of the beach drip with stalactites.

At one end, a cave holds a shrine to a sea princess, filled with offerings left by local fishermen for luck and safety at sea. In the morning, before the boats arrive, it is one of the most peaceful and photogenic places on the coast.

• Best for: scenery, swimming and photographers
• Getting there: walk from Railay, or take a long-tail from Ao Nang directly to the beach
• Where to stay: Railay, a short walk away
• Where to eat: food boats sell noodles and fruit on the beach; for a proper meal, walk back to Railay
• Best months: November to April
• Honest downside: long-tail boats crowd the shoreline in the middle of the day, so come early or late

3. Maya Bay (Koh Phi Phi Leh) – The Beach from the Film, Now Protected

Stunning Maya Bay on Phi Phi Island — famous for its crystal-clear waters, limestone cliffs, and serene tropical beauty.

Maya Bay became world-famous after the film The Beach, and the crowds that followed damaged its coral so badly that it closed in 2018. It reopened in 2022 under strict rules, and the recovery is visible: the water is clear again, and blacktip reef sharks are often seen in the shallows.

Boats can no longer enter the bay. Instead, visitors land on the other side of the island and walk in on a boardwalk, then enjoy the beach from the sand. It is a photo stop rather than a beach day, but the view of white sand enclosed by towering cliffs is unforgettable.

• Best for: photos and film fans
• Getting there: a day trip by boat from Phuket, Krabi or Koh Phi Phi Don; the national park fee is collected on the trip
• Where to stay: Koh Phi Phi Don, the neighbouring island, for an early-morning visit before the crowds
• Where to eat: there is no food in the bay; eat on Koh Phi Phi Don or on your tour boat
• Best months: November to April; the bay closes every year from 1 August to 30 September
• Honest downside: swimming is banned to protect the coral, so you can only paddle and look

>>> Make a trip of it: our 7-day Phuket tour includes the Phi Phi Islands and James Bond Island in Phang Nga Bay. From $530 per person.

4. Freedom Beach (Phuket) – A Hidden Cove Next to Patong

Freedom Beach in Phuket, a secluded stretch of white sand reached mainly by longtail boat, known for calm, exceptionally clear water.

Just south of busy Patong, Freedom Beach is a cove of white sand backed by jungle, with clear water and good snorkelling around the rocky ends. Because it can only be reached by boat or a steep path, it feels a world away from Patong’s bars, though it is only minutes away.

Come in the morning for calm water and fewer people, bring snorkelling gear, and plan to stay a few hours. For more of the island, see our Phuket travel guide.

• Best for: a quiet beach day while staying in Patong or Karon
• Getting there: a long-tail boat from the south end of Patong Beach, or a steep jungle path
• Where to stay: Patong for nightlife, or Karon for a calmer base
• Where to eat: a small beach restaurant in season; bring water as a backup
• Best months: November to April
• Honest downside: the boat fare adds up for a single couple, so share a long-tail with others

5. Mai Khao Beach (Phuket) – Phuket’s Longest and Quietest Beach

Mai Khao beach

Mai Khao stretches for about 11 km along Phuket’s north-west coast, inside Sirinat National Park, and it is the island’s wildest beach: no rows of beach bars, just sand, casuarina trees and a few low-rise resorts. Sea turtles still come ashore here to nest.

Planes landing at Phuket Airport pass low over the northern end, which makes it a favourite spot for plane spotters and a convenient last stop before an evening flight.

• Best for: long walks, quiet resorts and travellers with an early or late flight
• Getting there: a few minutes by car from Phuket Airport
• Where to stay: one of the resorts along the beach; there is no town here
• Where to eat: mostly in your resort, or at the seafood stalls near Sirinat National Park
• Best months: November to April
• Honest downside: strong currents in the monsoon make it unsafe for swimming from May to October

>>> Make a trip of it: pair a quiet stay at Mai Khao with the capital on our Bangkok and Phuket tour, which spends 8 days between the city and the island.

6. Donald Duck Bay (Similan Islands) – Thailand’s Clearest Water

Donald Duck Bay in the Similan Islands, named for its duck-shaped boulder and widely regarded as having the clearest water in Thailand.

The Similan Islands are a protected marine park about 65 km off the coast, with some of the clearest water and best coral in Thailand. Donald Duck Bay on Ko Similan (Island 8) is their most famous beach, a crescent of bright white sand below a granite boulder that gives the bay its name.

Snorkelling here is the main attraction, with turtles and reef fish close to the shore. Visitors are capped at 3,325 a day, and the park opens only from 15 October to 15 May, so it never feels as crowded as Phi Phi.

• Best for: snorkelling and the clearest water in Thailand
• Getting there: a speedboat day trip from Thap Lamu Pier near Khao Lak, about 1.5 hours each way; Phuket hotels can arrange transfers
• Where to stay: Khao Lak, the nearest beach town; overnight stays on the islands are no longer allowed
• Where to eat: lunch is included on day trips; Khao Lak has plenty of seafood restaurants
• Best months: 15 October to 15 May; visits run from 08:00 to 16:00
• Honest downside: the park fee is 500 THB (~$15) for adults, and the day is long and can be rough

>>> Make a trip of it: our Southern Thailand tour covers Phuket, Phang Nga Bay and Khao Lak, the gateway to the Similan Islands, in 5 days.

7. Sunrise Beach (Koh Lipe) – Island Life Near Malaysia

Sunrise Beach on Koh Lipe, the longest beach on this small southern island close to the Malaysian border, within Tarutao National Marine Park.

Koh Lipe, in Thailand’s far south, is a tiny car-free island with water clear enough to see fish from the shore. Sunrise Beach on the east coast has soft white sand, views of the jungle-covered islands of the national park, and snorkelling reefs a short swim away.

The island is small enough to walk across in 20 minutes, and its Walking Street fills with seafood barbecues and small bars in the evening. It is the place to slow down for a few days at the end of a trip.

• Best for: clear water, snorkelling and a laid-back island stay
• Getting there: a speedboat from Pak Bara pier in Satun, or a boat from Langkawi in Malaysia in high season
• Where to stay: Sunrise Beach for swimming, or Pattaya Beach on the south coast for restaurants
• Where to eat: Walking Street, the island’s centre, for Thai and seafood dinners
• Best months: November to April
• Honest downside: it is far from everywhere, and many boats stop in the rainy season

8. Long Beach (Koh Lanta) – Space for Everyone

Long Beach on Koh Lanta, a four kilometre stretch of sand with room to spread out, plus sunset bars and easy swimming.

Koh Lanta is the relaxed alternative to Phuket and Phi Phi, with long sandy beaches, mangroves and a national park at its southern tip. Long Beach (Phra Ae) is its liveliest stretch, with soft sand, gentle water in season and a mix of bungalows, family resorts and low-key bars.

It suits families and travellers who want space without the party scene, and day trips to the snorkelling islands of Koh Rok and Koh Haa leave from here in the dry season.

• Best for: families and budget travellers
• Getting there: a minivan with car ferries from Krabi, or a ferry from Phi Phi in high season
• Where to stay: along Long Beach for the most choice, or Kantiang Bay further south for quiet
• Where to eat: beach restaurants along the main road behind the sand
• Best months: November to April
• Honest downside: many businesses close or slow down in the rainy season

Best Beaches in the Gulf of Thailand

9. Sairee Beach (Koh Tao) – Diving and Sunsets

Sairee Beach on Koh Tao, the island’s main beach and the base for its dive schools, known for relaxed sunsets over the water.

Koh Tao is one of the world’s busiest places to learn to dive, thanks to warm, calm water and reefs close to shore, and Sairee, its longest beach, is where most dive schools are based. Even if you do not dive, the snorkelling at nearby bays such as Ao Leuk and the island of Nang Yuan is excellent.

In the evening, the whole beach turns west to watch the sun drop into the Gulf, and the beach bars come to life with fire shows and music.

• Best for: divers, snorkellers and sunset lovers
• Getting there: a ferry from Chumphon on the mainland or from Koh Samui and Koh Phangan
• Where to stay: Sairee village for restaurants and dive shops
• Where to eat: the beach bars and Thai restaurants in Sairee village
• Best months: February to August
• Honest downside: it gets lively at night; for quiet, stay at one of the small coves on the east coast

10. Haad Salad (Koh Phangan) – A Calm Bay Away from the Parties

Haad Salad on Koh Phangan, a sheltered bay with calm swimming and good snorkelling, well away from the island’s full moon party scene.

Koh Phangan is famous for the Full Moon Party, but Haad Salad on the north-west coast is its opposite: a sheltered bay with calm water, a coral reef for snorkelling and sunset views. Its name comes from the pirates who once hid here.

The bay’s gentle, shallow water makes it one of the best family beaches on the Gulf islands, and the small resorts along the sand keep the atmosphere relaxed.

• Best for: families and couples who want peace
• Getting there: a ferry from Koh Samui to Thong Sala pier, then about 20 minutes by car
• Where to stay: the small resorts along the bay
• Where to eat: the beach restaurants in the bay and the night market in Thong Sala
• Best months: February to August
• Honest downside: the water is very shallow at low tide, and the beach is small

11. Chaweng Beach (Koh Samui) – The Island’s Busiest Stretch

Chaweng Beach, the longest and liveliest beach on Koh Samui, lined with resorts, beach bars, and calm swimming water.

Chaweng is Koh Samui’s longest and liveliest beach, with powder-soft sand, warm water and everything from beach clubs to family resorts. Chaweng Noi, at its southern end, is calmer and better for swimming, while the central stretch is where the restaurants, shops and nightlife are.

It is the easiest base for a first Gulf trip: the airport is close, and day trips to Ang Thong Marine Park and the Big Buddha leave from nearby.

• Best for: first-timers, nightlife and travellers who want facilities
• Getting there: about 15 minutes by car from Samui Airport
• Where to stay: Chaweng Noi for quieter resorts, or central Chaweng to be near the action
• Where to eat: Chaweng’s beach road restaurants, or Fisherman’s Village in Bophut for a quieter dinner
• Best months: February to August
• Honest downside: it is crowded and built-up, and the sea can be rough from October to December

>>> Make a trip of it: our Thailand discovery tour pairs Bangkok and Chiang Mai with beach days on Koh Samui over 10 days.

12. Sai Kaew Beach (Koh Samet) – The Closest Island Beach to Bangkok

Sai Kaew Beach on Koh Samet, the closest proper island beach to Bangkok and an easy weekend escape from the capital.

Koh Samet is the easiest island escape from Bangkok, and Sai Kaew, its main beach, has fine white sand that squeaks underfoot. The island is a national park, so it stays greener than most, with quieter bays such as Ao Prao on the west coast.

In the evening, restaurants set up tables and seafood barbecues on the sand, often with fire shows. It is ideal for a 2- or 3-night break at the start or end of a trip.

• Best for: weekend trips from Bangkok
• Getting there: about 3 to 4 hours by road from Bangkok to Ban Phe pier in Rayong, then a short ferry or speedboat; a national park fee is collected on arrival
• Where to stay: Sai Kaew for convenience, or Ao Prao for sunsets and quiet
• Where to eat: the seafood barbecues set up on the sand in the evening
• Best months: November to April
• Honest downside: it gets very busy with Bangkok crowds at weekends and on holidays

>>> Make a trip of it: for quieter islands on the same eastern coast, our island-hopping tour visits Koh Mak, Koh Rang and Koh Kood in 6 days.

Practical Tips for Thailand Beach Holidays

A little preparation makes beach days safer and cheaper:

• Respect the flags: rip currents cause drownings every year, especially in the monsoon season, so never swim when red flags are up.
• Watch for jellyfish: box jellyfish stings can be dangerous, especially from May to October; some beaches have vinegar stations.
• Carry cash for park fees: marine parks such as the Similan Islands, Phi Phi and Koh Samet charge foreigners an entry fee, often collected by the boat crew.
• No smoking on the sand: smoking is banned on many popular beaches, with fines for offenders.
• Protect the reef: use reef-safe sunscreen and never stand on coral; several marine parks now check sunscreen.
• Book island transfers early in high season: boats to Phi Phi, Similan and Koh Lipe sell out around Christmas and New Year.
