Saint Vincent and the Grenadines lies to the west of Barbados, south of Saint Lucia and north of Grenada in the Windward Islands of the Lesser Antilles, an island arc of the Caribbean Sea. The islands of Saint Vincent and the Grenadines include the main island of Saint Vincent  and the northern two-thirds of the Grenadines , which are a chain of smaller islands stretching south from Saint Vincent to Grenada. There are 32 islands and cays that make up St Vincent and the Grenadines (SVG). Nine are inhabited, including the mainland St Vincent and the Grenadines islands: Young Island, Bequia, Mustique, Canouan, Union Island, Mayreau, Petit St Vincent and Palm Island. Prominent uninhabited islands of the Grenadines include Petit Nevis, used by whalers, and Petit Mustique, which was the centre of a prominent real-estate scam in the early 2000s.
