south twin island

South Twin is a grassy, tree-topped island, 1 km long, lying in an east-west direction. There are two small bays on the south side.

Topographically similar to The Similan Islands, South Twin Island has deep, large rock structures forming gullies, long swim-through passages and overhangs.

In the shallows you'll find Fine Table Corals hidden amongst the boulders. There are Tiger Cowries here and the elusive Ribbon Eel. Look carefully, as they are really very small, only showing maybe 3cm above their holes in the sand. Male Ribbon Eels are black and females blue with bright yellow fins.
