The United States Virgin Islands (USVI) are located in the Caribbean bordered by the Atlantic Ocean and Caribbean Sea. The USVI consist of 4 larger islands: St. Croix, St. Thomas, St. John and Water Island, and some 50 smaller islets and cays. The island of St John, at just 9 miles long and 3 miles wide (28 sq mi), is the smallest of the US Virgin Islands.
Since 1956, full two-thirds of St. John's 20 square miles (53 square km) is protected as Virgin Islands National Park, administered by the United States National Park Service.
