The Costa Blanca (Valencian: [ˈkɔsta ˈβlaŋka], also [ˈkɔstɔ ˈβlaŋka]; Spanish: [ˈkosta ˈβlaŋka], literally meaning "White Coast") is over 200 kilometres (120 mi) of Mediterranean coastline in the Alicante province, on the southeastern coast of Spain. It extends from the town of Dénia in the north, beyond which lies the Costa de Valencia, to Pilar de la Horadada in the south, beyond which lies the Costa Cálida. The name Costa Blanca was coined in the 1950s as a way to promote tourism.
