North side (Turtle Harbor Marine Reserve) On the lip of the Continental Shelf, a plateau at 25 feet, edged by pillar and mountainous star coral, hosts an active fish nursery. This platform gives way dramatically to a sheer, deep wall extending well below 3000 feet in many places making it the perfect milieu for deep or technical diving.

On the wall sparse hard corals, due to the northern exposure, are crowded by profuse sponge formations. Expect dog snapper, mackerel, grouper, and rays at depth. Occasional hawksbill and green turtles are seen nesting and feeding on the shelves. Turtle Harbor, as the name suggests, is a turtle nesting ground and a favorite feeding area for the larger aquatic animals such as Manta Rays, dolphins and the largest fish in the sea, the Whale shark.

Abundant pillar coral edges a 30 feet (9 meters) plateau thick with soft corals, and chimneys allow shafts of light to pierce the cavern system below. Swim by cavern after cavern along a 65 feet (19 meters) plateau running east to west. The wall and the caves themselves host an incredible collection of tube, rope, and vase sponges, some growing over l2 feet long (3 meters). Look for resident midnight parrotfish and dog snapper.

The water colour takes on a unique blue tropical color with the reflections from the sandy bottom. Grunts, goatfish, spotted drum, porcupine fish, and puffers are common to this area. The wall does have huge red and yellow rope and tube sponges on the overhangs.
