This dive site is found on the small island of Koh Chi within the Surin Islands group and is another very good dive site in the Similan Islands area. It is located with the National Marine Park of the Similan Islands and Surin Islands and as a protected area, the reef is in very good condition. The dive itself is around 18 to 20 meters and is made up of a sloping reef with some boulders on the sandy bottom. The dive site can be somewhat exposed which can make it a challenging dive as it can mean there are strong currents. Divers should be alert to this and make plans accordingly when diving here.
The site mainly has hard corals but there are some sea fans, and soft corals around. The hard corals are home to many reef fish and if investigated further, divers may spot invertebrates and crustaceans lurking amongst the coral.
The larger pelagic fish sighted here include Tuna, Barracuda, and Trevally. Whale sharks and manta rays have been spotted here as they are common in the area but this is rare. More likely is seeing a sea snake or a turtle.
