About Black Rock / Ulua Cave

Black Rock is mainly a wall dive with depths of between 40 to 90 feet and a huge cavernous chamber roughly 100 feet long and 50 feet wide. The mooring buoy will allow you to go to 55 feet, which is also the top of the rock outcropping. The room has various entry and exit points due to erosion. A drop of 90 feet over a near wall takes one to a massive underwater chamber where one can view white-tip reef sharks and turtles. Amazing hard coral polyps can be viewed living on the ceiling as well as the sporadic Kona crab or spiny lobster. Visibility is good as long one takes care not to kick up sand.
