The U.S. Virgin Islands are an unincorporated U.S. territory comprising three main islands: St. Thomas, St. Croix, and St. John. While tourist areas are generally safe and well-patrolled, some crime does occur, particularly property crime; travellers should avoid isolated areas after dark and secure valuables. The territory is located in the Atlantic hurricane belt, with the season from June to November; Hurricanes Irma and María caused severe damage in 2017. The Roy Lester Schneider Hospital on St. Thomas and the Governor Juan F. Luis Hospital on St. Croix provide medical care, though capacity can be limited. Visitors should carry comprehensive travel insurance and be aware that prices for goods and services can be higher than on the U.S. mainland.
