One mile long, partially paved road over beachrock ridge leaves Queen's Highway to the east (Atlantic side) across from phone booth along highway. About 4 miles north of Clarence Town, Long Island, Bahamas. See Google Earth imagery for access details (not that difficult) through sparsely settled subdivision within a half mile of the blue hole.
This is the world's deepest blue hole at 663' and is situated in a scenic location on an attractive and reef-protected cove with a white sand beach. The blue hole is immediately off the beach and half surrounded by overgrown beachrock cliffs. It is the location of the establishment of a new world's freediving record in April, 2007. At the surface the blue hole is about 200' in diameter. It funnels down into a narrower throat about 100' in diameter, opening again with increasing depth (~100) to resemble a bottle of Lancers in profile. Exotic non-native lionfish have been observed frequently in the blue hole environs. Nearby coves also provide Atlantic Ocean side reef/cove diving opportunities.
