Known as the deepest blue hole in the world with a depth of 663 feet, Dean's Blue Hole is the most amazing sight on the island. A blue hole is a term for a water-filled sinkhole with an entrance below the water level. Free divers from around the world gather here annually to take the plunge. In 2010 William Trubridge broke the world record free-diving to 302 feet without fins. Dean's Blue Hole is surrounded by a pretty cliff and a superb beach. The shallows at the edge
of the hole are perfect for snorkeling and swimming, and the more adventurous visitors can jump into the water from the cliffs above. To find the blue hole, watch for the well-marked sign on your left (going east on Queen's Highway) after passing through Scrub Hill.
