Providenciales, known locally as Provo, is an island in the Turks and Caicos archipelago, in the Atlantic Ocean. It’s ringed by soft, sandy beaches, many of them on the north coast. These include expansive Grace Bay Beach, a water sports hub with resorts, shops and restaurants. The island’s snorkel sites include Smith’s Reef and Bight Reef. The turquoise lagoon of Chalk Sound National Park is dotted with tiny cays.
