The United States Virgin Islands are a group of several dozen islands and cays located in the Caribbean, about 1100miles southeast of Florida, 600miles north of Venezuela, 40miles east of Puerto Rico, and immediately west and south of the British Virgin Islands.
The U.S. Virgin Islands lie near the boundary of the North American Plate and the Caribbean Plate, roughly 100miles south of the Puerto Rico Trench and near the Anegada Passage, a key shipping lane. Together with the British Virgin Islands, Vieques, and Culebra, they make up the Virgin Islands archipelago.
The hilly, volcanic islands of Saint Thomas (31sqmi[1]) and Saint John (20sqmi) border the North Atlantic Ocean to the north and the Caribbean Sea to the south. The larger island of Saint Croix (84sqmi) lies 40miles to the south across the Virgin Islands Trough and is entirely in the Caribbean Sea.
Charlotte Amalie, Saint Thomas is one of the best natural, deepwater harbors in the Caribbean. The Islands have many well-known beaches, including Magens Bay (Saint Thomas) and Trunk Bay (Saint John), and coral reefs, including the Virgin Islands Coral Reef National Monument and the Buck Island Reef National Monument. More than half of Saint John and nearly all of Hassel Island are owned by the U.S. National Park Service.
