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.
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.
Llanes is a traditional fishing port, with an active harbour and many notable monuments and traditions; one plaque commemorates the 65 sailors from Llanes who sailed on the three ships it fitted out for the Spanish Armada in 1588 (the Santa Ana, the San Nicolas, and the Santelmo). Parts of the surviving town walls date to 1206. Another plaque commemorates the visit of Emperor Charles V on September 26, 1517, who, when on his way to Valladolid to be crowned King of Castile, stayed for two nights before resuming his journey.
