Sail Rock is approximately 50 minutes speedboat journey north from Koh Samui, between Koh Phangan and Koh Tao and is a pinnacle shaped like an iceberg that rises out of the water creating a fantastic wall dive.
Sail Rock is stunning at depths of 5 metres and down to a maximum depth of 40 metres, so it is ideal for beginners and experienced divers alike. There are sometimes relatively strong currents on parts of the site, but the site is big enough for you to dive and avoid the current.
Sail Rock is famous for the vertical "Chimney", which begins at around 16m and opens at the top around 6m and is great fun to ascend through. Sail Rock is one of the main sites in the area for sightings of Whale Sharks, but if they aren't around there are always schools of Barracuda, large schools of Yellow Fusiliers, many schooling Trevally, Giant Morays, Large Groupers, Batfish and a great variety of other fish.
