Koh Ha Yai

Dive Location:  Southernmost of the Koh Ha island group.
Depth: Average 18m / Maximum 25m

There is excellent adventure here. The south western face has a cave with two large entrances. The western of these is a hole in the rock at a depth of 5m. This immediately enters the larger of two connected cathedrals, which rise an impressive 30m above sea-level. The other entrance/exit, at the eastern end, is deeper, at 16m.

It is not dark in the cathedrals; light enters from the waters below. Directly in front of the cave are a number of large rocks highlighted by sea fans and soft corals. There are also plenty of sea whips, which are worth closer inspection as it will reveal a variety of tiny camouflaged invertebrates.
