Grand Cayman is everything you want in a Caribbean island. The surrounding waters are home to vibrant coral reefs and sunken sculpture parks that lure divers and snorkelers. Topside, the vibe is mellow, with tidy gingerbread-trimmed homes and eclectic attractions like the conservation-minded Cayman Turtle Farm. Cruise ships anchor offshore near George Town, the capital city and a world financial center (this is a British overseas territory).
