Thailand's Best Beaches

Phuket — Thailand's Largest Island

Phuket is Thailand's most popular beach destination, attracting millions of visitors each year. Connected to the mainland by the Sarasin Bridge, this island offers everything from buzzing nightlife to secluded coves. Phuket International Airport (HKT) receives direct flights from across Asia, Europe, and the Middle East.

Patong Beach

The heart of Phuket's tourism scene. Patong is a 3.5-kilometer stretch of sand lined with hotels, restaurants, and shops. Bangla Road comes alive at night with bars, clubs, and street performances. Patong suits travelers who want everything at their doorstep — jet skis, parasailing, massage parlors, and international dining. It is the busiest and loudest beach on the island.

Kata Beach

A favorite among families and couples, Kata Beach is quieter than Patong but still has plenty of restaurants and shops. The beach is about 1.5 kilometers long with soft white sand and reliable surf from May to October. Kata Noi, the smaller beach just south, is even more relaxed. Surf schools operate here during monsoon season, making it one of the few places in Thailand to learn to surf.

Karon Beach

One of Phuket's longest beaches at 3 kilometers, Karon is wide and uncrowded compared to Patong. The sand here is distinctively squeaky underfoot. The southern end has a coral reef accessible by snorkeling. Karon has a good mix of mid-range and upscale hotels and is a solid choice for travelers who want beach time without constant noise.

Nai Harn Beach

Tucked into Phuket's southern tip, Nai Harn is a local favorite with a laid-back atmosphere. The beach is framed by green hills and a Buddhist monastery. Swimming is excellent from November to April, but strong currents can form during monsoon months. Nai Harn has fewer hotels than other Phuket beaches, giving it a more authentic feel. Nearby Promthep Cape is the best sunset viewpoint on the island.

Other Notable Phuket Beaches

Freedom Beach — accessible only by longtail boat, this hidden cove has crystal-clear water and pristine sand. Surin Beach — upscale area with beach clubs and luxury resorts. Mai Khao — Phuket's longest beach (11 km), part of Sirinat National Park, and home to sea turtle nesting sites from November to February. Rawai — not a swimming beach but a great seafood hub with longtail boats to nearby islands.

Koh Samui — Gulf of Thailand's Crown Jewel

Thailand's second-largest island sits in the Gulf of Thailand, about 35 kilometers off the Surat Thani coast. Koh Samui has its own international airport (USM), operated by Bangkok Airways, with direct flights from Bangkok, Singapore, Hong Kong, and Kuala Lumpur. The island blends tropical beauty with excellent infrastructure — five-star resorts, world-class spas, and a thriving food scene.

Chaweng Beach

The longest and most popular beach on Koh Samui, stretching 7 kilometers along the east coast. Chaweng is the island's commercial center with shopping malls, restaurants, nightclubs, and beach bars. The northern end is quieter while the central strip has the most action. ARKbar Beach Club is an institution for sunset cocktails. Water is calm and swimmable most of the year.

Lamai Beach

The second-busiest beach, south of Chaweng, with a more relaxed vibe. Lamai attracts a mix of couples and long-stay visitors. The beach is about 4 kilometers long with good swimming conditions. The famous Hin Ta and Hin Yai (Grandfather and Grandmother Rocks) — natural rock formations — are at the southern end. Lamai has a lively Sunday night market with local food and crafts.

Bophut Beach & Fisherman's Village

On Samui's north coast, Bophut combines a beautiful beach with one of the island's most charming areas. Fisherman's Village is a narrow street of converted Chinese shophouses now housing boutique hotels, cafes, art galleries, and restaurants. The Friday Walking Street market is a highlight — live music, Thai food stalls, and handmade goods. Big Buddha temple (Wat Phra Yai) sits on a small island connected by causeway at the eastern end.

Other Samui Beaches

Maenam Beach — quieter, budget-friendly, popular with long-stay visitors and families. Lipa Noi — the best sunset beach on the island, very peaceful. Choeng Mon — a small cove in the northeast, upscale and intimate. Taling Ngam — remote west-coast beach with dramatic coastal views and the Five Islands panorama.

Koh Phi Phi & Krabi

The Krabi coastline and its offshore islands form one of the most photographed landscapes in Southeast Asia. Towering limestone karsts rise from emerald waters, and the beaches are consistently rated among the world's most beautiful.

Koh Phi Phi Don

The only inhabited island in the Phi Phi archipelago, Phi Phi Don is car-free and walkable. Tonsai Bay is the arrival point with restaurants, bars, dive shops, and budget accommodation packed into a narrow isthmus. The famous viewpoint — a steep 20-minute climb — rewards you with one of Thailand's most iconic panoramas: twin bays curving on either side of the island. Long Beach on the southeast side is quieter and better for swimming.

Maya Bay (Koh Phi Phi Leh)

Made famous by the 2000 film "The Beach" starring Leonardo DiCaprio, Maya Bay was closed from 2018 to 2022 for environmental recovery. It has since reopened with strict visitor limits — a maximum of 375 visitors at a time, no swimming in the bay, and visits capped at one hour. Boats now dock at a new pier on the back of the island, and visitors walk through a short trail. Entry is around ฿400 (about US$12) per person. Despite the restrictions, the bay's towering cliffs and turquoise water remain stunning.

Railay Beach, Krabi

Accessible only by boat despite being on the mainland, Railay is cut off by limestone cliffs. This peninsula has four beaches: Railay West (the best for swimming and sunsets), Railay East (mangrove-lined, home to most accommodation), Phra Nang Beach (consistently ranked among the world's best, with a cave shrine), and Tonsai Beach (rock-climbing mecca). Railay is the top destination in Southeast Asia for rock climbing, with over 700 bolted routes on the karst cliffs.

Ao Nang, Krabi

The main tourist hub of Krabi province, Ao Nang is the gateway to Railay, the Four Islands, and Koh Phi Phi. The beachfront road is packed with hotels, restaurants, tour agencies, and shops. Longtail boats depart from the beach to nearby islands. Ao Nang itself is not the prettiest beach, but it is an excellent base for exploring the region.

Four Islands Tour

A popular day trip from Ao Nang visiting Koh Tup, Koh Mor (connected by a sandbar at low tide), Koh Poda (excellent snorkeling), and Phra Nang Cave Beach. Longtail boat tours cost around ฿800-1,200 (US$24-36) per person including lunch and snorkeling equipment. Speedboat versions are available for around ฿1,500-2,000 (US$45-60).

Koh Tao — Diving Paradise

This small island (21 square kilometers) in the Gulf of Thailand is one of the cheapest and most popular places on Earth to get scuba diving certified. Koh Tao certifies more PADI Open Water divers than anywhere else in the world. Calm, warm waters (28-30°C), excellent visibility (up to 40 meters on good days), and affordable prices draw divers from beginner to advanced.

Diving & Snorkeling

An Open Water certification takes 3-4 days and costs around ฿9,000-12,000 (US$270-360), often including accommodation. Top dive sites include Sail Rock (the region's best, with whale sharks from March to May), Chumphon Pinnacle (schools of barracuda and giant grouper), Japanese Gardens (colorful coral, great for beginners), and Shark Island (hawksbill turtles and reef sharks). Snorkeling is free at many beaches — Aow Leuk and Shark Bay are excellent shore-entry spots where you can swim with blacktip reef sharks and sea turtles.

Beaches

Sairee Beach — the longest beach (1.7 km) and main strip with bars, restaurants, and dive shops. Sunsets here are outstanding. Chalok Baan Kao — a peaceful bay in the south, shallow and calm, good for families. Tanote Bay — a scenic east-coast bay with great snorkeling right from shore. Freedom Beach — small, secluded, accessible by a jungle trail or boat.

Getting to Koh Tao

Koh Tao has no airport. The most common route is to fly to Koh Samui (USM) or Surat Thani (URT), then take a ferry. Lomprayah and Seatran operate high-speed catamarans from Koh Samui (1.5 hours, ฿600/US$18) and from Chumphon on the mainland (1.5-2 hours, ฿600/US$18). Night boats from Surat Thani take about 8 hours and cost around ฿400 (US$12).

More Island Gems

Koh Lipe — The Maldives of Thailand

Thailand's southernmost inhabited island sits in the Tarutao National Marine Park, just 30 kilometers from the Malaysian border. Koh Lipe has three main beaches: Sunrise Beach (east, calm and scenic), Sunset Beach (west, great for sunsets and snorkeling), and Pattaya Beach (south, the arrival point). The coral reefs here are some of the healthiest in Thailand. Koh Lipe is small enough to walk across in 20 minutes. The island is accessible by speedboat from Pak Bara pier (1.5 hours) or seasonal ferries from Koh Lanta and Langkawi, Malaysia. Best visited November to April — the island largely shuts down during monsoon season.

Koh Chang — The Elephant Island

Thailand's second-largest island (after Phuket) sits in the eastern Gulf near the Cambodian border. Koh Chang is less developed than Phuket or Samui, with a mountainous, jungle-covered interior and waterfalls. White Sand Beach is the main tourist strip, while Lonely Beach and Bang Bao are more laid-back. The island is reachable by a short flight to Trat airport (TDX) followed by a 30-minute ferry, or by bus from Bangkok's Eastern Bus Terminal (5-6 hours) to the ferry pier. Koh Chang is part of the Mu Ko Chang National Park.

Koh Lanta — The Relaxed Alternative

Long Beach (Phra Ae), Klong Dao, and Kantiang Bay offer wide stretches of sand without the crowds. Koh Lanta attracts families, couples, and digital nomads who want beach life at a slower pace. The island has a charming Old Town on the east coast — a former trading port with wooden stilt houses, now home to cafes and small shops. Koh Lanta is a 2-hour minivan ride from Krabi airport, including a short car-ferry crossing. The southern tip has Mu Ko Lanta National Park with a lighthouse and secluded beaches.

Koh Phangan — Beyond the Full Moon Party

While famous for its monthly Full Moon Party at Haad Rin beach, Koh Phangan has much more to offer. The north coast (Bottle Beach, Thong Nai Pan) has some of the island's most beautiful and quiet beaches. Srithanu on the west coast is a wellness and yoga hub. The island has excellent snorkeling at Sail Rock and the Ang Thong National Marine Park is a day trip away. Ferries run frequently from Koh Samui (30 minutes) and Surat Thani.

Similan Islands

A group of nine islands in the Andaman Sea, about 70 kilometers off the Phang Nga coast. The Similans are consistently rated among the top 10 dive sites in the world. The islands are open only from mid-October to mid-May and require a national park entry fee of ฿500 (US$15) for foreigners. Day trips run from Khao Lak (about 1.5 hours by speedboat) and cost ฿2,500-3,500 (US$75-106). Overnight stays are possible in basic national park tents and bungalows — book well in advance.

Best Time to Visit — Gulf vs. Andaman Seasons

Thailand has two coastlines with different monsoon seasons, which means there is always a good beach to visit somewhere in the country.

Andaman Coast (West) — Phuket, Krabi, Koh Lanta, Koh Lipe, Similan Islands

Best season: November to April. This is the dry season with calm seas, clear skies, and the best visibility for diving and snorkeling. December to February is peak season with the highest prices and most crowds. March and April are hot but still dry. The monsoon hits from May to October — some resorts and islands (especially Koh Lipe and the Similans) close entirely. Phuket and Krabi remain open year-round but expect rain, rough seas, and some beach closures during monsoon months.

Gulf Coast (East) — Koh Samui, Koh Phangan, Koh Tao

Best season: March to September. The Gulf has a different weather pattern — its monsoon runs from October to December, with November being the wettest month. This means the Gulf islands are at their best when the Andaman coast is in monsoon season, and vice versa. January and February can also be pleasant on the Gulf side. Koh Samui, Koh Phangan, and Koh Tao stay open year-round.

Eastern Gulf — Koh Chang, Koh Kood, Koh Mak

Best season: November to May. The eastern islands follow a similar pattern to the Andaman coast. The driest months are December to February. The monsoon from June to October brings heavy rain and rough seas, though the islands remain accessible.

Quick Season Reference

Beach Tips & Practical Info

• National park fees — Most marine national parks charge ฿300-500 (US$9-15) for foreign adults. Keep your receipt if visiting multiple days.
• Longtail boats — The iconic wooden boats are the main transport between beaches and small islands. Always agree on a price before boarding. Typical cost: ฿100-300 per person for short trips.
• Jellyfish season — Box jellyfish can appear in the Gulf of Thailand from July to October. Look for warning signs on beaches and consider wearing a rash guard.
• Coral protection — Reef-safe sunscreen is increasingly required at national parks. Avoid touching or standing on coral.
• Red flags — Take beach warning flags seriously. Rip currents cause drownings every year, especially during monsoon season. Swim between the flags where lifeguards are present.
• Island hopping — Lomprayah and Seatran Discovery offer multi-island ferry passes. You can also book combined bus-ferry tickets through 12Go Asia or directly from ferry operators.
• Water shoes — Useful for rocky beaches and protecting against sea urchins, especially at Koh Tao and the Similan Islands.
