The Protected Landscape of the West Coast of Asturias is the coastal area of the concejos of Cudillero and Valdés. This space encompasses a total of 6,204 hectares, bordering Barayo Natural Reserve to the west and the Natural Monument of Las Dueñas Mire to the east. Between the two spaces there is a 35-kilometer abrasion platform with cliffs, sand and pebble beaches, and small coves. The cliffs that best represent the west coast of Asturias rise up near Cape Busto and Cape Vidio; the latter is also the site of Iglesona Cave, which was formed by the movements of the sea and can be visited during low tide. The estuary of the Esva River and La Cueva Beach make up another natural space of interest on the west coast. Throughout this section, there are several very pleasant beaches, such as Silencio, Concha de Artedo, and San Pedro de la Ribera.
The vegetation is distributed among the species of undergrowth that grow on the cliffs and the grass, birch, and oak formations on the elevated land. Regarding the fauna, the European shag is one of the most representative species of the west coast; alongside it appear other birds like the seagull and the peregrine falcon. You can also see species common to northern Spain like wild boars, foxes, squirrels, and badgers.
The abrasion platform of the western Asturian coast has numerous marked paths leading to the areas of cultural and natural interest, linking together the small towns found along the coast. Some of the best paths are the PR-AS-4, the Cape Busto Route, and certain sections of the GR-9.
Entrances: Highway N-632 marks the southern limit of the west coast and facilitates access to the scenic overlooks, beaches, and towns (like Cudillero and Luarca) that are found in and around this natural space.
