Three Islets
This site is known variously as "Shark Cave", "Three Islets", "Three Stooges", and "In Through The Out Door". There is a canyon which leads to a small underwater cave that can be swum right through. Grey reef sharks were common in the canyon, and large nurse sharks were common in the cave, but both have become increasingly rare. Nevertheless a very interesting site with probably the greatest diversity of species in the Mergui Archipelago. Blotched fantail rays can be seen, as well as seahorses, scorpionfishes, Phraraoh cuttlefish etc.. Great care should be taken in the canyon and cave, as occasional bouts of "surge", which don't look serious on the surface, can cause very strong currents underwater. Liveaboard Three Islets is also known as Shark Cave.
