Grand Turk is the capital of Turks & Caicos, a longtime favorite destination for divers eager to explore the 7,000-foot-deep pristine coral walls that drop down only 300 yards out to sea. On shore, the tiny island is home to white-sand beaches, the National Museum, and a few wild horses and donkeys, which leisurely meander past the white-walled courtyards, pretty churches, and bougainvillea-covered colonial inns on their daily commute into town.
