Fodor's Expert Review Dean's Blue Hole

Known as the second deepest blue hole in the world with a depth of 663 feet, Dean's Blue Hole is the most amazing sight on the island and one of the most popular photo sites in the land. 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 for free immersion diving to 407 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).
