Llanes (the Concejo de Llanes, Conceyu de Llanes in Asturian language) is a municipality of the province of Asturias, in northern Spain. Stretching for about 30 km along the coast at the extreme east of the province, Llanes is bounded to the south by the high ridge of the limestone Sierra del Cuera, which rises to over 1,100 m. The region is part of the Costa Verde (Green Coast) of Spain, which is known for its spectacular coastal scenery, with 32 white sand beaches, and mountains covered with a deep green mantle. Llanes lies to the north of the Picos de Europa, a mountain range whose geology is almost entirely of limestone karst.
