This dive site is located near Koh Phangan and accessed primarily through special full-day trips or as the main departure point for daily trips. Sail Rock, a substantial pinnacle rising from the seabed, is the focal point. The surrounding waters are renowned for their vibrant biodiversity. Visitors often encounter inquisitive batfish that gather to pose for photographs, alongside impressive Malabar groupers—some hidden amongst overhangs and others swimming freely. Schools of Chevron and Pickhandle barracuda frequently reside near the pinnacle. Whale sharks are a seasonal highlight as they feed in this area. For those interested in macro life, opportunities abound to observe shrimps, crabs, Wart Slugs, and various species of Nudibranchs. The Chimney, a vertical swim-through, presents a compelling buoyancy challenge; entering at approximately 18 meters leads to a garden of Lobed Pore Coral around 8 meters, with Groupers and Soldierfish inhabiting the darker recesses along the way.
