Deans Blue Hole

Dean's Blue Hole is one of the world's most spectacular dive sites, located on Long Island in the Bahamas. This massive underwater sinkhole plunges to over 200 meters, making it the deepest known blue hole on Earth. The circular opening is surrounded by a sandy beach and shallow lagoon before dramatically dropping into the abyss. While freediving and technical diving are the main draws, the shallow rim area is beginner-friendly with crystal-clear waters and fascinating geological formations.
