The Cantabrian Sea[a] is the coastal sea of the Atlantic Ocean that washes the northern coast of Spain and the southwest side of the Atlantic coast of France; it represents the south area of the Bay of Biscay. It extends from the cape Estaca de Bares in the province of A Coruña, to the mouth of the Adour river, near the city of Bayonne on the coast of the department of Pyrenees Atlantiques in French Basque Country.
The sea washes 800 km (500 mi) of coastline shared by the Spanish provinces of A Coruña, Lugo, Asturias, Cantabria, Biscay and Gipuzkoa, and the French area of Labourd.
