The three islands of the Cayman Islands are the exposed top of an underwater mountain, which makes for great diving. Scuba divers from all over the world come to the Caymans for its coral reefs, colorful fish and other underwater marine life. The diving on Grand Cayman is divided roughly into 4 areas; Seven Mile Beach and the Northwest Point, The North Wall, The South Side, and The East End. On Little Cayman, Bloody Bay Wall and Jackson Bay are commonly dive destinations.
Don't forget your underwater cameras! Also the Caymans cater to the scuba diving crowd so lessons and certification are available at most resorts.
