Dreaming of soft white sand, turquoise waters, and palm-fringed shores? Thailand’s beaches are among the most beautiful in the world – each offering its own charm, from secluded hideaways to iconic movie spots and vibrant tropical coves.
In this 2025 guide, we unveil the 10 most beautiful beaches in Thailand, highlighting where to go, what to expect, and why each destination deserves a place on your travel bucket list.
Why Thailand’s Beaches Are So Popular
Thailand’s diverse coastline stretches across two seas: the Andaman Sea (west coast) and the Gulf of Thailand (east coast). This geography creates a wide variety of beaches — perfect for relaxing, snorkeling, diving, and exploring.
- Andaman Sea (Phuket, Krabi, Koh Phi Phi, Koh Lanta, Similan Islands): best from November to April
- Gulf of Thailand (Koh Samui, Koh Phangan, Koh Chang): best from May to September
Whether you’re chasing sunsets or vibrant coral reefs, there’s a perfect beach for every season.
Top 10 Most Beautiful Beaches in Thailand
1. Donald Duck Bay – Similan Islands
Located in the heart of the Similan Islands National Park, Donald Duck Bay is famous for its massive granite boulders and crystal-clear water. The beach is accessible only by boat and is protected under marine conservation, keeping its beauty intact. Ideal for snorkeling and photography, its white-sand crescent beach and towering rock formations (including the “Donald Duck Head” shape) create a truly unique scene.
Best for: snorkelers, nature lovers, photographers
Tip: Only accessible during the dry season (Nov–Apr)
2. Railay Beach – Krabi
Accessible only by boat due to surrounding limestone cliffs, Railay Beach offers one of the most dramatic landscapes in Thailand. It’s split into two sides: West Railay (perfect for sunsets and swimming) and East Railay (a haven for rock climbers). Towering karst cliffs, jungle trails, hidden lagoons, and peaceful vibes make Railay a must-visit.
Best for: couples, photographers, adventure seekers
Tip: Hike to the Railay viewpoint for a jaw-dropping panorama
3. Kantiang Bay – Koh Lanta
Nestled in southern Koh Lanta, Kantiang Beach is a quiet stretch of golden sand framed by lush hills and calm waters.

Boutique resorts like Pimalai Resort & Spa blend luxury with nature, making it a great spot for travelers who want both comfort and authenticity.
Best for: quiet luxury, couples, digital detox

4. Maya Bay – Koh Phi Phi
Made famous by The Beach movie, Maya Bay is as iconic as it gets. After a long closure to allow for environmental recovery, it has recently reopened with new rules to protect its ecosystem. Its towering cliffs, turquoise lagoon, and white sand make it one of the most photographed places in Thailand — and for good reason.
Best for: sightseeing, day trips, movie lovers
Tip: Visit early morning to avoid the crowds
5. Karma Beach – Koh Lipe
A lesser-known gem on Koh Lipe, Karma Beach is small but stunning. It offers powder-soft sand, warm shallow water, and colorful coral reefs just meters from the shore. Unlike the more developed Pattaya Beach nearby, Karma Beach remains peaceful and uncrowded — perfect for a quiet swim or sunset view.
Best for: snorkeling, couples, tranquility
Tip: Bring reef-safe sunscreen — the marine life is vibrant!
6. Chaweng Noi Beach – Koh Samui
Often overshadowed by its big sister Chaweng Beach, Chaweng Noi is a hidden paradise on Koh Samui’s east coast. It features soft white sand, clear calm water, and a more relaxed atmosphere. High-end resorts and restaurants line the beach, offering comfort without the party scene. It’s a great spot for families and couples looking for peaceful luxury.
Best for: families, wellness retreats, relaxed stays

7. Bottle Beach – Koh Phangan
Accessible by boat or jungle hike, Bottle Beach (Haad Khuat) is one of Koh Phangan’s best-kept secrets. It features soft white sand, emerald waters, and a remote, untouched feel. Small bungalows and rustic restaurants dot the shoreline, giving it a classic backpacker-meets-nature vibe.
Best for: off-the-beaten-path travelers, adventurers
Tip: Bring cash — there are no ATMs or major services
8. Khao Phing Kan – Phang Nga Bay (James Bond Island)
Often referred to as James Bond Island, Khao Phing Kan rose to fame after appearing in The Man with the Golden Gun. But beyond the fame, this island offers surreal natural beauty — dramatic cliffs, hidden caves, and a signature limestone stack rising vertically from the sea. It’s best visited as part of a day tour through the Phang Nga Bay, which includes sea kayaking through nearby lagoons and mangroves.
Best for: sightseeing, boat tours, photographers
Tip: Combine with a visit to Koh Panyee, a floating village
9. Koh Ngam Beach – Koh Chang
Tucked away on the eastern side of Koh Chang, Koh Ngam Beach is a hidden jewel that feels like a private paradise. This secluded beach lies on a small island just off the coast of Koh Chang and is connected to the mainland by a narrow sandbar that emerges at low tide. Surrounded by lush hills and framed by calm, emerald-green waters, Koh Ngam offers a serene escape from the more touristy parts of the island. The setting is ideal for couples and travelers seeking peace, nature, and authentic Thai island charm. With minimal infrastructure and only a few local vendors, the beach remains quiet and pristine. Visitors often arrive by boat or kayak, adding to the sense of adventure and discovery.
Best for: peace and quiet, nature lovers, romantic getaways
Tip: Visit during low tide to walk across the sandbar connecting Koh Ngam to the mainland
10. Kata Noi Beach – Phuket
Located just south of the busier Kata Beach, Kata Noi offers a peaceful slice of Phuket’s west coast. The beach is framed by green hills and features clear blue water, soft sand, and gentle waves. Popular with families and couples, it’s perfect for swimming, bodyboarding, or simply relaxing in a quieter setting.
