Koh Muk

Dive Location:  Outcrop off Koh Muk’s northwest point.
Depth: Average 5m / Maximum 10m

The rock is covered in splendid purple and red soft corals, with holes and cracks providing hiding places for reef inhabitants. You can head either south along the west coast or east along the north coast – both options offer overhangs, but the latter is the most interesting. More significant than the diving on offer, there’s an interesting adventure for snorkellers – assuming they feel brave enough to navigate the winding cave/tunnel, 60m long, which has been cut through the western rocky cliff.

Known as Morukut (Emerald Cave), this penetrates the mountain and eventually emerges into a beautiful lagoon, about 60m across, fringed by tropical forest, and with a superb beach.

The tunnel affords the only access by water to this lagoon; the water at its entrance is only about 4m deep and becomes shallower as the tunnel goes deeper into the mountain, while there is always at least 1m airspace and sometimes as much as 15m.
