Dominant features

    A network of caverns and canyons notched out of the coral wall. Large coral outcroppings in the shallower sections are honeycombed with narrow chasms and chimneys large enough for divers to explore. Skylights in the caverns send shafts of sunbeams down into the depths.


    Varied hard coral walls honeycombed with crevices and fissures, some of which rise up to openings inside on the lagoon floor. The vertical walls are rich in soft corals.

    Fish Life

    Whitetip reef sharks are often found resting in the sandy bowls within the crevices. Expect a wide variety of reef fish and schooling pelagics. Sometimes schools of fifty or more huge Parrothead Humpbackfish are found outside the caverns. At the bottom of the outer mini-wall, Gray reef sharks are frequently seen. Morays and Stingrays are often seen near or within the caverns. Large schools of Tuna & Amberjack heve been sighted off the entrance. Lionfish abound.
