To hell and back might serve as the catchy, tongue-in-cheek title of this intriguing half-day tour on Grand Cayman. Any missives you mail from the local post office will sport a postmark from Hell. Inspired by a strangely discomforting landscape of black limestone formations, the name Hell stuck, and the appellation has only added to the attraction's devilish allure. So be sure to bring your cameras and snail mail and celebrate this Caribbean oddity. In addition to Hell, Grand Cayman is home to the Cayman Turtle Centre. One of the islands delicacies is the famed rum cake you'll discover on your tour. Sample the cakes, and perhaps buy one to enjoy back home.
