Llanes (the Concejo de Llanes, Conceyu de Llanes in Asturian language) is an administrative district of the province of Asturias, in northern Spain. Stretching for about 30km 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 1,100m. The region is part of the Costa Verde (Green Coast) of Spain, which is known for its spectacular coastal scenery, beaches, and mountains. Llanes lies to the north of the Picos de Europa, a mountain range whose geology is almost entirely of limestone karst.
Most of the inhabitants of the district live on the coastal plain, on which the largest town is Llanes itself, with a population of about 4,000 out of the total for the district of about 13,000. The folklore, food, and fiestas of the region are famous for their colour and history.
