For some, a day swimming with sharks is a dream come true, the ultimate thrill. The island is home to many species, including tiger, bull, and great hammerheads, who pay a visit between December and April. More docile species include nurse and reef sharks. There are lots of opportunities to swim with sharks, including a day spent at the Bull Run, so named for its popularity with bull sharks, which provides guests with the opportunity to view these mighty fish from the safety of a cage.
