The Black Hole Wall dive site is one of Little Cayman's Island's many mysterious and beautiful spots that draw adventurous divers seeking the thrill of the deep. The abyss meets the reef at the edge of a dramatic 6000 foot plunge to the bottom of the Caribbean Sea's deepest trench. These advanced divers will only be able to descend 100 feet below the surface. They must carefully gauge their bottom time or they risk decompression sickness and disaster. But the unique and beautiful sights so far below the waves makes such a journey worthwhile. Divers who are lucky enough to experience this magical place are often reluctant to return to the surface.
