Explore Sail Rock

Sail Rock (Hin Bai) is a world-famous site, and for good reason. Boasting unbelievable numbers of marine species and topography that’s just as exciting. It’s no surprise that it’s one of the most visited sites in the Surat Thani region. With its intense variety, you can dive here multiple times and it’ll feel like a different story each time. 

Situated around an hour and a half from Koh Tao, Sail Rock rises 8 meters from the surface, and plunges over 40 meters. The second rock on the south east side of the site drops to around 30 meters, while other smaller rocks pepper the sandy areas and host an array of life.  

The rock itself is extremely unique, as you can dive inside it through a vertical swim-through known as “The Chimney.” Divers typically enter at 18 meters and ascend single file to the exit at around 6 meters. The rest of the site is navigated easily, as you simply circle the rock moving upwards slowly.  

The abundant dive centers and resorts on the islands visit the site daily, and normally visit its equally famous sibling as part of the same trip, the Chumphon Pinnacle. The area is one of Thailand’s busiest diving hubs, so there’s no lack of availability even in the high season. For those diving fanatics that want to dive multiple places without staying on the islands, liveaboards also make rounds in the region and usually include Sail Rock on their to-do list. 

Furthermore, it may be possible to dive Sail Rock as part of a dive course, especially a deep specialty or advanced course, thanks to suitable training conditions.
