With 64,660 hectares, covering three autonomous communities; Asturias, Cantabria and Castilla-León, the Picos de Europa form the largest protected area in Spain. They are composed of limestone rock, with a rugged relief, product of water and ice erosion, being some of its most famous and famous places the "Lagos de Covadonga", of glacial origin, so called because of its proximity to the Basilica of Covadonga.
It is said that the name Picos de Europa is due to the sailors who, when they returned from their marine incursions, the first thing they saw were the imposing peaks of the mountains that adorn the park. The Naranjo de Bulnes (locally known as Pico Urriellu), is perhaps the most emblematic peak, since its strange shape and altitude (2519 meters) attracts climbing and mountain lovers.
With its steep gray peaks bare of vegetation, its countless chasms (more than 10% are more than 1000 meters deep), its green-painted sheepfolds, its caves and its impressive gorges, such as the Cares River, led to its being declared a Biosphere Reserve by UNESCO in 2002. Crossed by countless trails, the park offers spectacular scenery, given that you can practice extreme sports such as climbing, hiking or taste the famous Cabrales cheeses and visit Sotres, considered the highest village in Asturias (at 1,050 meters above sea level).
