This world-renowned blue hole, an inland ocean/swimming hole, is located on the southern edge of Rock Sound. People often drink and bathe in its brackish water, rumored to have healing powers. A seemingly bottomless natural limestone formation, it is said to have been explored by Jacques Cousteau. Ocean Hole is filled with tropical fish and turtles who will sidle up and greet visitors. The fish that live in Ocean Hole were caught and put there by local residents. There is no fishing allowed, but you can swim and feed the fishes. You can also see a variety of local bird species nesting in the hardwood trees.
