Dive site highlights
Shark island
Shark Island is just 10 minutes from the resort, making it one of Koh Tao’s most convenient and inviting dive sites, almost like diving in your own backyard. This beautiful site offers a relaxed yet rewarding experience, with vibrant coral gardens and a wonderful sense of calm beneath the surface. Divers can enjoy encounters with big schools of barracuda, batfish, and trevally, along with giant groupers and graceful blue-spotted stingrays gliding over the reef. There’s also the chance to spot turtles and, on special days, even a whale shark passing through. With depths ranging from 5–30 meters, Shark Island is perfectly suited to both Open Water and Advanced divers, offering an easy-going yet diverse underwater adventure close to home.
Shark Bay
Shark Bay is a lively and exciting bay just to the east of Sai Daeng Beach. It is named after the blacktip reef sharks that frequent here. This bay is also a shark nursery, so you may spot baby sharks swimming along the shoreline at Sai Daeng Beach. Keep an eye out for green turtles as they live in the bay. There is also a giant green turtle, which is the main attraction. There is an entrance fee when using the beach, but you may kayak there for free!
Tanote Bay
Tanote Bay is the next bay past Aow Leuk and is known for its scenic, rocky cove with exceptionally clear water and vibrant coral reefs. This bay is popular with snorkelers thanks to the abundant marine life, including a massive school of Goldband Fusilier fish. Tanote Bay has an enormous granite boulder that juts out of the water, perfect for experienced cliff jumpers. The beach tends to remain quiet making it ideal for a peaceful escape.
Koh Nang Yuan
Koh Nang Yuan is comprised of three small islands connected by a sandbar. Its unique landscape has made it a popular feature in books and postcards. The island has great snorkeling and scuba diving sites. It is said to be one of the most beautiful islands in the world. For an extra treat, charter a private longtail boat from Sai Daeng Resort.
Chumpon Pinnacle
Chumphon Pinnacle, just one hour from the resort, is widely regarded as Koh Tao’s premier dive site and delivers an exhilarating experience for advanced divers. Descending to depths of 15–30 meters, this legendary pinnacle is surrounded by massive schools of barracuda, fusiliers, trevally, and batfish, with giant groupers hiding among the rocks and exciting swim-throughs waiting to be explored. With dramatic underwater scenery and the thrilling possibility of a whale shark encounter, Chumphon Pinnacle offers unforgettable diving at its most spectacular.
Southwest Pinnacle
Southwest Pinnacle, located just 30 minutes from the resort, is one of Koh Tao’s most renowned dive sites and a favourite for both Open Water and Advanced divers. This stunning underwater pinnacle, ranging from 10–30 meters in depth, is home to large schools of barracuda, fusiliers, and trevally, alongside resident giant groupers and blue-spotted stingrays resting on the sandy seabed. During the season, divers may even be fortunate enough to encounter the majestic whale shark, making every dive here truly unforgettable.
White Rock
White Rock, just 10 minutes from the resort, is Koh Tao’s largest and one of its most widely dived sites, famous and frequently visited by dive operators across the island. Known for its easy layout and impressive scale, it offers something for every level of diver, with depths from 5–30 meters and plenty to explore. The site is alive with big schools of barracuda, batfish, and trevally, alongside blue-spotted stingrays resting on the sandy patches and occasional sightings of turtles. Divers can also enjoy gentle swim-throughs and, on lucky days, even a whale shark passing through. Its combination of accessibility, variety, and consistent marine life makes White Rock a dependable favourite and a staple on many dive itineraries in Koh Tao.
Twin Rock
Located just south of Koh Nang Yuan, Twins is one of Koh Tao’s most iconic and accessible dive sites, where three granite pinnacles rise through clear, sheltered waters. With depths ranging from 5 to 18 metres and a sandy bottom, it is an ideal setting for learning and refining buoyancy skills while protecting the surrounding coral. The pinnacles are embraced by thriving coral and the innovative Buoyancy World artificial reef project, creating a sanctuary for colourful tropical fish and marine life. Look closely for blue-ringed angelfish, butterflyfish, longfin bannerfish, white-eyed moray eels and delicate Christmas tree worms.
