Hin Ton Mai also known as South Rock is a very popular dive spot as the fish life is very varied with lots of Moray Eels and Barracuda. Very Large Marble Rays (250 CM wing tip to wing tip) have been spotted there, though not often. There are plenty of both hard and soft corals, coral whips as well as very good invertebrate life such as nudibranchs, brittle stars and feather stars. This site has very good coral life down to 22 metres.The south east and south side of the island offers yet again a different dive site. On the south east side, there are many well preserved corals, as not many people actually visit them and they are well populated by Yellow Jacks, Yellow Tail Fusiliers and Morays. In early September, 2011. We, in cooperation with The Dive Tribe, released around 30 Sharks in this area, including 2 Black Tip Reef Sharks, 10 Banded Bamboo Sharks and 18 Bamboo Sharks. Moving around to the south side, the corals thin out but the topography boast nice cliffs and valleys down to depth of about 14 meters.The secret dive site is a small wreck that attracts a swarm of yellow jacks as seen on the video that also attracts 6 to 8 very large Cobia Fish around 1 meter 50 cm plus long..
