Head to Sail Rock for Even More Diving

Experienced divers will want to check out this popular diving site between Koh Tao and Koh Phangan, marked by a huge limestone rock jutting 10 meters out of the water. This famous wall dive, with a maximum depth of about 40 meters, is known for being one of the best areas in Thailand for swimming with a range of exotic fish, and even whale sharks if you're lucky.

You can also see giant black coral, moray eels, and large schools of fish, such as batfish, snapper, and trevally. Another feature is the vertical chimney swim-through. While popular with experienced divers, Sail Rock is actually suitable for all levels of divers, depending on conditions.
