Fodor's Expert Review Treasure Cay Blue Hole

You'll need a car or at least a bicycle to visit this natural wonder, but it's worth the trek. Scientists believe the Treasure Cay Blue Hole is 200 feet deep, but feel free to dip your toes into the crystal-clear blue waters or make a splash swinging from one of the rope swings tied to surrounding pine trees. The water is both salt and fresh and there is no known marine life in the blue hole.
