Once a hideout for pirates, today Grand Cayman is world-reknowned for its clear waters and coral reefs. The water is so incredibly clear and teeming with tropical fish, sponges and coral so vivid it will take your breath away. Snorkel the surface, take a submarine ride to the depths, or see all from a glass bottom boat. Seven Mile Beach is considered one of the Caribbean's most beautiful shorelines with talcum-soft sand. In Georgetown, shop for black coral jewelry or try a taste of West Indian yam cake. There's also a turtle farm to visit.
