Home to fruit bats, herons, wild green parrots and an abundance of tropical foliage, the 12-mile-long island of Cayman Brac boasts more than 170 caves and 1400 inhabitants. Named after the imposing limestone bluff, or Brac in Scottish Gaelic, that looms 140 feet above the sea, the middle Cayman offers spectacular diving at Wilderness Wall and Peter's Cave. Emerald green parrots flock at the National Trust Parrot Reserve. To discover some of the island's secrets, take a taxi, hop on a bike or trot on foot.
