Published on 09/15/2026 at 14:32 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
The mountain range known as Picos de Europa forms a compact band of limestone peaks in the Cantabrian Mountains of northern Spain, with Cangas de Onis on the Asturian side acting as a gateway into this steep landscape. The area gained formal protection as a national park in 1918 under the name Montaña de Covadonga, and the present Picos de Europa National Park spans parts of Asturias, Cantabria and Castile and León as a recognised Biosphere Reserve within Spain’s Man and the Biosphere network.
Limestone massifs compressed between rivers and sea
Picos de Europa extends for about 20 km (12 mi) and forms one of the most compact high mountain systems on the Iberian Peninsula, with peaks concentrated in a relatively small footprint of roughly 646 square kilometres.extends for about 20 km The range belongs to the Cantabrian Mountains and consists largely of pale limestone, which gives the cliffs and summits a stark presence above the surrounding valleys.spectacular limestone massifs
The mountains are divided into three main massifs known as the Western or Cornión, the Central or Urrieles and the Eastern or Ándara, separated by deep river gorges that cut through the rock between Asturias, Cantabria and León.three massifs From some summits the Cantabrian Sea lies only around 15 km (9 mi) to the north, so the high ridges rise abruptly from terrain that drops towards the coast in a short distance.Cantabrian Sea a mere 15 km This compressed geography, with peaks, gorges and nearby sea, gives the range its characteristic contrast between alpine forms and maritime setting.
Picos de Europa National Park and Covadonga landscape
The protected area known as Picos de Europa National Park covers more than 64,000 hectares of mountainous terrain and straddles the autonomous communities of Asturias, Cantabria and Castile and León, with municipalities such as Cangas de Onis contributing territory on the Asturian side.Cangas de Onis contributes territory The park’s origins lie in the declaration of the Montaña de Covadonga National Park in July 1918, associated with the Peña Santa massif and the historic landscape around Covadonga.Montaña de Covadonga National Park
Within the Western or Cornión massif, above Cangas de Onis and Covadonga, lie the Lakes of Covadonga, high mountain tarns set among pastures and bare limestone slopes that have become a recognised part of the park’s identity.Lagos de Covadonga area The broader park has been designated as a Biosphere Reserve under UNESCO’s Man and the Biosphere Programme, reflecting the variety of Atlantic ecosystems, high meadows and rocky summits within its boundaries.Biosphere Reserve designation Across its massifs the park contains habitats ranging from beech and oak woodlands in lower valleys to karst plateaus, cliffs and high cirques with sparse vegetation.
Cangas de Onis as a gateway to gorges and high paths
Cangas de Onis stands in Asturias a short distance north-west of the central band of summits and functions as an access town for the Western or Cornión massif, with roads leading towards Covadonga and the Lakes of Covadonga.approach from Oviedo and Cangas de Onis The municipality contributes several thousand hectares to the national park and provides lower-lying services, accommodation and visitor information, including a visitor reception centre for the park on Avenida Covadonga in the town.visitor reception centre
From Cangas de Onis, travellers encounter the transition from river valleys such as the Sella to steep roads, tracks and footpaths climbing towards high pastures, lakes and rocky ridges in the national park.plan your visit information The wider range can also be reached from towns such as Potes and Posada de Valdeón, but Cangas de Onis remains an important north-western gateway that connects the urban fabric of Asturias with the mountain paths of Picos de Europa.gateway towns
