Picos de Europa: limestone peaks above Cangas de Onis
Published on 08/24/2026 at 09:53 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Picos de Europa is a compact limestone mountain range in northern Spain, rising between deep river gorges and high glacial pastures above towns such as Cangas de Onis. Created as a protected area in 1918, it became Spain’s first national park and later expanded into the present Picos de Europa National Park, which spans parts of Asturias, Cantabria and Castile and León in the Cantabrian Mountains.Spain’s first national park The range itself covers around 646 km² (249 mi²), with its highest summit, Torre Cerredo, reaching 2,648 m (8,688 ft) above sea level.Torre Cerredo at 2,648 m
Limestone massifs and dramatic gorges
The core of Picos de Europa is formed by three main limestone massifs, separated and cut through by deeply entrenched river valleys. The western massif, known as Cornión, lies above Cangas de Onis between the Sella and Cares rivers, anchoring the park’s presence in the municipality.the Cornión massif above Cangas de Onis To the east, the rugged central and eastern massifs rise in jagged ridges and narrow cols, giving the range its characteristic serrated skyline.
Much of the rock is pale, hard limestone, carved by water into sheer cliffs, sinkholes and long gorges that cut into the heart of the range.limestone formations and Atlantic ecosystem Below the peaks, the valleys and lower slopes carry Atlantic forests of beech and oak, while intermediate terraces support upland pastures where traditional transhumant grazing has left stone shelters and seasonal hamlets. The contrast between vertical cliffs and gently rolling meadows is one of the most striking features of the landscape.
From Covadonga to the wider national park
The protected story of Picos de Europa began in 1918 with the creation of the Montaña de Covadonga National Park around the Lakes of Covadonga in the western massif, near the Covadonga Sanctuary.Montaña de Covadonga created in 1918 These glacial lakes, Enol and Ercina, lie at about 1,134 m (3,720 ft) and formed the original core of the protected area, a high basin enclosed by peaks and used for summer grazing.Lakes of Covadonga at 1,134 m
Later expansions brought the surrounding massifs and valleys into a single national park, which is now recognised both as Picos de Europa National Park and as a UNESCO Biosphere Reserve.UNESCO biosphere reserve designation in 2003 The park extends across eleven municipalities and three autonomous communities, including Cangas de Onis in Asturias, and preserves habitats ranging from subalpine limestone cliffs to mixed Atlantic woodland and montane pastures.spread across Asturias, Cantabria and León
Cangas de Onis and the western approaches
Cangas de Onis lies on the Asturian side of Picos de Europa, at the foot of the western Cornión massif and close to the access road to the Lakes of Covadonga. The municipality contributes over 7,000 hectares of its territory to the national park, integrating its uplands and valleys into the protected landscape.Cangas de Onis contribution to the park From the town, roads climb through forested slopes and past viewpoints towards the high basins and ridges of the western massif.
The wider park remains an inhabited mountain area, with villages, livestock and traditional routes woven into the relief.Spain’s only inhabited national park Old stone settlements, chapels and farm buildings appear on balconies and valley bottoms, while high passes and tracks cross between valleys and link the western side with the central and eastern massifs. Standing on a ridge above Cangas de Onis, the view reaches from distant Cantabrian Sea horizons to the broken limestone towers at the heart of Picos de Europa.
