Home to the R. City brothers the Virgin Islands are the western island group of the Leeward Islands, which are the northern part of the Lesser Antilles, and form the border between the Caribbean Sea and the Atlantic Ocean. Made up of St Croix, St John and St Thomas, the laid-back USVI offer sophisticated dining, turquoise waters and quaint towns. On St Croix, Christiansted's colourful Danish Colonial buildings provide a lovely backdrop for dining or sailing, and underwater coral gardens are heaven for divers. On St Thomas, shopping mecca Charlotte Amalie has hopping nightlife. Tranquil St John offers quiet trails, secluded coves and lively Cruz Bay's shops and bars. Ferries and local air services link the islands.
