Fuerteventura (pronounced: [fweɾteβenˈtuɾa]; literally meaning "strong fortune" but translated by some as "Strong Winds" or a corruption of the French term for "Great Adventure") is one of the Canary Islands, in the Atlantic Ocean off the coast of Africa, politically part of Spain. At 1,660 square kilometres (641 square miles), it is the second largest of the Canary Islands, after Tenerife. It was declared a biosphere reserve by UNESCO in May 2009. Its capital is Puerto del Rosario.
