Sail Rock stands out as one of the premier open-ocean dive sites in the Gulf of Thailand. Rising from a sandy seabed at over 30 meters to break the surface, this dramatic granite pinnacle acts as a magnet for diverse marine life, offering an exceptional two-dive experience for certified divers.

Beneath the surface, divers can encounter massive schools of pelagic fish, alongside giant groupers, moray eels, nudibranchs, and extensive fields of sea anemones thriving across hard and soft corals. The open-water location also brings the exciting possibility of seasonal whale shark encounters.

One of the site's most celebrated features is "The Chimney," a natural vertical swim-through that divers can enter at 18 meters and ascend inside the rock to exit at 6 meters. Between dives, enjoy lunch and refreshments during a relaxing surface interval aboard the boat.

Speedboat transfers reduce travel time from Koh Samui to approximately 60 minutes, ensuring more time exploring the dive site and less time in transit. To maintain safety and personal attention, dive groups are kept small with dedicated guidance throughout.

This two-tank expedition pairs the deep offshore pinnacles of Chumphon with a sheltered reef dive off Koh Tao, welcoming certified divers, Discover Scuba participants, and snorkelers.

Located northwest of Koh Tao, Chumphon Pinnacle consists of massive granite peaks rising from depths of 30 meters to around 14 meters beneath the surface. The underwater ridges run southwest to northwest and are carpeted in dense sea anemone beds host to pink anemonefish. Schools of chevron barracuda, bigeye trevally, batfish, and queenfish congregate in the open blue, with occasional sightings of passing whale sharks.

During the first dive at Chumphon, snorkelers are transferred to the calm waters of nearby Mango Bay to explore the shallow fringing reefs. Following the morning dive, guests regroup on board for lunch and a surface interval before heading to a second, shallower Koh Tao dive site, where hard coral gardens and macro life provide relaxed underwater conditions.

For certified divers, Discover Scuba beginners, and snorkelers.

Located roughly 35 kilometers west of Koh Samui, Angthong Marine National Park spans an archipelago of 42 uninhabited limestone islands rising steeply from turquoise waters. While famous for its dramatic karst cliffs and hidden lagoons, the park's underwater world provides exceptional shallow reef diving and snorkeling in protected conditions.

Key dive and snorkeling sites include Koh Wao and Koh Yippon at the northern perimeter of the marine park. Here, submerged limestone formations create underwater caves, arches, and swim-throughs encrusted with colorful soft corals, tube sponges, and black coral trees. Marine life in the marine park includes blue-spotted stingrays, yellowtail snappers, fusiliers, cuttlefish, and regular sightings of hawksbill turtles.

With calm waters and gentle depths ranging from 5 to 18 meters, Angthong is ideally suited for mixed groups of certified divers, beginners completing Discover Scuba sessions, and family members snorkeling on the surface.
