Western coast of Cantabria
The Western Coast of Cantabria is a "comarca" of said Spanish autonomous community which comprises the municipalities of Val de San Vicente, San Vicente de la Barquera, Valdáliga, Comillas, Udías, Ruiloba, Alfoz de Lloredo and Santillana del Mar. As its own name indicates, this "comarca" extends over the western coast of the autonomous community, from its border with Asturias by the mouth of the Deva River, to the Saja-Besaya mouth in Suances, although this limits may vary depending on the source, since this "comarca", as the rest of Cantabria's, is not regulated, but there  are common characteristic elements in the municipalities that belong to it. This zone has great tourism assets like beaches, nature, gastronomy and culture. Santillana del Mar, Comillas, Suances and San Vicente de la Barquera are the municipalities of greater renown, both in the "comarca" and in Cantabria, so they are the main destinations for tourists. Three of the longest rivers of Cantabria flow into the Western coast: The Deva, the Nansa and the Saja-Besaya. In addition to the numerous beaches, the Oyambre Natural Park and Mount Corona stand out as natural attractions. As has been mentioned, the culture of  the zone is quite remarkable, since in a few kilometers-radius many cultural spots are concentrated: the Altamira Cave and Museum, the Zoologic and Botanic Garden, the Collegiate Church in Santillana del Mar; and the Sobrellano Palace, the Comillas Pontifical University and the Gaudí Caprice in Comillas. The Cantabrian West is a mainly touristic "comarca", that opposed to the East, it had remained safe from the massive house buildings because of the lateness of the construction of the Cantabrian Motorway, completed in the early 2000s
