This large limestone formation extends approximately 40 Km. Long (east-west) and about 20 Km. Wide (north-south). Her constitution forces her to continually submit to the demanding erosion of rain and snow, which take their toll on her constitution and excavate deep chasms that are very attractive in the world of speleology. Some reach 1.400 meters depth. Morphologically speaking we find in Los Picos de Europa three clearly differentiated beds.
The three massifs: Cornión, Urrieles and Andara
The western massif (El Cornión), the central massif (Los Urrieles), and the eastern massif (Andara). They are physically delimited by the gorges of the salmon rivers Sella, Cares, Duje and Deva. The western massif, with its highest point, Peña Santa de Castilla (2.596 m.), is the largest and most varied of the three, and it is particularly suitable for hiking. In this massif The lakes of Enol and Ercina are located, and very close to the Buferrera area, the environmental interpretation center of the Picos de Europa National Park. The easiest way to approach him is from the town of Covadonga, ascending a local and winding road to the famous lakes, 12 kilometers above, from where a good number of recommended routes for all audiences depart. It should be noted that the end of summer and early autumn, as well as spring are usually the best times for such a walk, since neither the heat nor the presence of hikers is excessive.
The central massif he is the most uninhabited, in him we find the highest point of the three massifs and northern Spain: Torre Cerredo (2,648m.) The boundary with the western massif is drawn by the famous and spectacular route that runs through the Cares gorge. Bulnes the last town of Asturias without external communication, is also found in this massif and was always a must for climbers on the way to Picu Urriellu or Naranjo de Bulnes (2.519m), one of the biggest challenges for national and international climbers due to its extreme vertical walls. The town that gives its name to the singular Naranjo was connected to the rest of the Cabrales council by a mule road, but a funicular train until the town, accompanied by a good number of controversies, that came to break drastically the isolation of the village. Access to the northern point of the Cares and Bulnes gorge is via Poncebos, a few kilometers from the town of Arenas de Cabrales.
The southern face of the Picos de Europa is reached from Potes, in Cantabria, and Posada de Valdeón, in León. From Potes you can go to Source of and take the cableway up to an altitude of 1.800 m. In the whole area this is the easiest way to gain altitude quickly for excursions of a more alpine character. Posada de Valdeón is located in the southern point of Cares Gorge, after the town of Cain.
The agency S-cape Travel located in Arenas de Cabrales offers in Picos de Europa self-guided hiking trips; 12 and 8 day trips, 3 day trips and trips for families.
