This large limestone formation extends approximately 40 km in length (east-west) and about 20 km in width (north-south) . Its composition subjects it to continuous erosion from rain and snow, which wear down its structure and carve out deep chasms that are very attractive to speleologists . Some reach depths of up to 1.400 meters. Morphologically speaking, the Picos de Europa are divided into three clearly differentiated massifs.
The three massifs: Cornión, Urrieles and Andara
The western massif (El Cornión), the central massif (Los Urrieles), and the eastern massif (Andara) are physically delimited by the gorges of the salmon rivers Sella, Cares, Duje, and Deva. The western massif , with its highest peak, Peña Santa de Castilla (2.596 m), is the largest and most varied of the three, and is particularly suitable for hiking . Lakes Enol and Ercina are located in this massif , and nearby is the Buferrera area, the environmental interpretation center of the Picos de Europa National Park. The easiest way to reach it is from the town of Covadonga , ascending a winding local road to the famous lakes, 12 kilometers further up, from where a number of recommended routes for all levels begin.

It should be noted that the end of summer and beginning of autumn, as well as spring, are usually the best times for a walk of this type, since the heat is neither excessive nor the presence of hikers.
One of the most beautiful and spectacular routes in the Western Massif, near the Lakes of Covadonga, is the well-known Majadas Route . A fabulous journey through beautiful and evocative places, former shepherds' huts that often also serve as stunning vantage points between peaks, offering breathtaking views of the true silence of the Picos de Europa and their magnificent landscapes.

The central massif is the most sparsely populated, and it contains the highest point of the three massifs and of northern Spain : Torre Cerredo (2,648m). The boundary with the western massif is marked by the famous and spectacular route through the Cares Gorge. Bulnes, the last village in Asturias with no external access, is also located in this massif and has always been a necessary stop for mountaineers on their way to Picu Urriellu or Naranjo de Bulnes (2.519m) , one of the greatest challenges for national and international climbers due to its extreme vertical walls.
