Koh Ma

Dive Location:  Off the northwest coast of Koh Phangan.
Depth: Average 9m / Maximum 30m

This is considered the most interesting Koh Phangan site. The marine life is good and the corals reasonably healthy. Away from the reef are schools of fusiliers, red snappers and blue-striped grunts; groups of cuttlefish occasionally mingle with pairs of Imperial and blue-ringed angelfish. Honeycomb groupers, parrotfish, wrasse and butterflyfish stay closer to the reefs, and anemones and sponges encrust it.

The reef itself consists mainly of numerous boulders of lesser star, double star and brain corals of varying sizes; the deeper waters have black corals dividing up the rocky borderline.
