10. Hin Wong Bay
Hin Wong Bay is a paradise for snorkelers and divers, thanks to its vibrant coral reefs and the wide array of marine life that call it home. Shoals of colorful fish, swaying sea anemones, and even blue-spotted rays can be seen beneath its clear waters.
While the bay’s rocky shoreline makes walking tricky, many visitors opt to explore by kayak instead. A handful of hilltop bungalows offer sweeping views of the bay, perfect for a tranquil stay—though don’t expect amenities right on the beach.
9. Sai Daeng Beach
If you’re hoping to swim with reef sharks or spot sea turtles, Sai Daeng Beach is a must-visit. This picturesque beach is popular for snorkeling and kayaking, especially if you want to reach nearby Shark Island in under 30 minutes.
While access is through two adjacent resorts, the beach remains open to all visitors. Its laid-back charm and marine diversity make it a go-to for underwater adventures.
8. Freedom Beach
Tucked away at the southern tip of Koh Tao, Freedom Beach is one of the island’s best-kept secrets. The constant water flow around the point attracts large schools of fish just meters from shore.
From here, you’ll get a great view of the iconic Buddha Rock. Several hiking trails start nearby, leading to Taa Toh Yai Beach and a cliffside viewpoint that offers unforgettable ocean panoramas.
7. Sai Nuan
Sai Nuan isn’t just a single beach—it’s actually two small, peaceful coves separated by a rocky formation. Tucked away from the crowds, Sai Nuan is perfect for travelers eager to escape the island’s busier tourist spots. You can reach it either by boat or by hiking a scenic trail from Mae Haad.
This beach is all about natural beauty and relaxation. With no massive resorts or loud parties, you’ll find yourself surrounded by hammocks, rustic beach huts, and the sound of the ocean. The real highlight here is the snorkeling—spot sea turtles, unicornfish, and batfish gliding through the clear waters just off the shore.
6. Sairee Beach
The heart of Koh Tao’s beach scene is Sairee Beach, the island’s most popular and accessible shoreline. If you’re arriving by ferry, it’s likely the first beach you’ll see, and it’s easy to see why it draws such a crowd.
Lined with restaurants, bars, dive shops, and hotels, Sairee Beach is ideal for travelers who want everything within walking distance. The water is shallow close to shore, making it kid-friendly, while the coral reef begins farther out, making swimming safe. Whether you want to try a diving course, sip cocktails by the sea, or join a beach volleyball game, this beach has it all.
5. Chalok Bay
Chalok Bay is one of Koh Tao’s largest and most laid-back beaches, easily reachable from the nearby town. Though it’s not known for the best snorkeling or diving, it shines as a great swimming beach with long stretches of white sand.
This bay also serves as a hub for longtail boat trips, making it a great launching point for exploring the island’s hidden coves. If you’re looking for comfort, there are plenty of restaurants, beach bars, and shops nearby. Chalok Bay is perfect for a chill day in the sun.
4. Shark Bay
Don’t let the name fool you—Shark Bay is a popular snorkeling destination, named after the shy and harmless black-tip reef sharks that roam its waters. The bay is also a haven for green sea turtles, many of which grow over three feet long. Watching these gentle creatures swim is a magical experience.
Also known as Ao Thian Ok, Shark Bay borders a resort, but the beach remains open to the public. The white sand and vibrant turquoise water create postcard-perfect scenery, and the coral reef makes it an underwater wonderland.
3. Ko Nang Yuan
Just a short boat ride from Koh Tao lies Ko Nang Yuan, a trio of tiny islands connected by a sandbar. A favorite for day trips, this picturesque spot is all about adventure and beauty. You can reach it by longtail boat—or, for the thrill-seekers, via zipline from the mainland.
Ko Nang Yuan is a top diving and snorkeling destination thanks to its clear waters and abundant marine life. There’s only one restaurant on the island, offering both Thai and Western dishes, but the focus here is on nature, not nightlife.
2. Ao Leuk
Ao Leuk, a protected bay, is one of Koh Tao’s most stunning beaches. The sandy center gently slopes into the water, while coral reefs decorate both ends of the cove, making it perfect for snorkeling and diving.
Although there’s a small entrance fee to access the beach, it includes perks like cold drinks, beach chairs, and parking—making it a fantastic value. The calm waters and extra amenities also make Ao Leuk a family-friendly spot where kids can swim safely.
1. Ao Tanot Bay
Ao Tanot Bay, or Tanote Bay, is one of Koh Tao’s premier diving locations. Whether you’re a certified diver or a complete beginner, this is the place to dive into a new underwater adventure. Diving schools and guided tours are available right by the beach.
The bay is easily accessible by road and offers restaurants, accommodations, and dive centers—all without feeling overly crowded. If you’re seeking a place with incredible marine life, gorgeous views, and a peaceful atmosphere, Ao Tanot Bay delivers the best of both worlds.
