Llanes 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; Parts of the surviving town walls date to 1206 with a medieval Tower of Llanes remaining. There is a romanic-gothic Basilica dedicated to the Virgin Mary. 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). Another plaque commemorates the September 26, 1517 visit of Emperor Charles V who stayed for two nights, when on his way to Valladolid to be crowned King of Castile. In the 1990s the landmark old Theatre (Teatro Benevente), built as part of the main bridge over the river, was pulled down.

Llanes economy is boosted by tourists mostly from the rest of Spain in the summer. The town has traditional shops and restaurants, both in and around the town, and the zona de copas is lively at night in summer. Three beaches and a cliff-top walk, the Paseo de San Pedro, add to the coastal atmosphere.[citation needed] Nearby is the Playa de Gulpiyuri.>
