Picos de Europa and Cangas de Onis: limestone peaks above glacial lakes
Published on 09/14/2026 at 13:30 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
In northern Spain, the mountain range known as Picos de Europa lifts pale limestone peaks above deep valleys and glacial lakes, forming one of the most compact high mountain landscapes in Europe. The range belongs to the broader Cantabrian Mountains and lies within the autonomous communities of Asturias, Cantabria and Castile and León, with the Asturian town of Cangas de Onis long serving as a gateway to its western slopes.Cantabrian Mountains in northern Spain Much of this terrain is protected as Picos de Europa National Park, a status first granted to its core around the Lakes of Covadonga in 1918, making it the first national park declared in Spain.created in 1918
Limestone massifs and narrow gorges
Picos de Europa is structured around limestone massifs that rise over surrounding valleys, carved by rivers into deep gorges and cirques. The protected area of the national park extends over tens of thousands of hectares, with the wider range covering around 646 km² (249 mi²).National Park area Within this relatively compact space, peaks climb to more than 2,500 m (8,202 ft), while the northern edge of the park lies close to the Cantabrian Sea, creating a sharp transition between Atlantic coast and high mountain terrain.peaks above sea level
The limestone rock gives the range its pale colouring and steep faces, with cliffs, pinnacles and scree slopes dropping into valleys that carry rivers towards the sea. Over geological time, glacial erosion and water have opened gorges that define the boundaries of the range, while underground drainage creates caves and sinkholes within the higher plateaus. The setting brings together Atlantic vegetation in lower areas and alpine meadows on upland pastures, reflecting the park’s role as an Atlantic ecosystem.Atlantic ecosystem
The Lakes of Covadonga above Cangas de Onis
On the Asturian side of Picos de Europa, above Cangas de Onis, the Lakes of Covadonga form one of the most recognisable features of the range. These glacial lakes, known in Spanish as Lagos de Covadonga, comprise Enol and Ercina, with a third lake, Bricial, appearing seasonally in a nearby depression.Enol and Ercina They lie at over 1,000 m (3,281 ft) above sea level and occupy hollows carved by ice in the western massif of the range.over 1,000 metres above sea level
The lakes sit in a landscape of rolling pastures and limestone outcrops, where cattle graze on meadows that drop gently to the water. Tracks and paths run between viewpoints and former mining areas such as Buferrera, while nearby hills offer views across the lakes towards higher summits.circular route around the lakes For Cangas de Onis, the ascent to the Lakes of Covadonga is a defining excursion into the national park, linking the town with upland terrain that was central to the original park designation.
A protected landscape with long-standing status
Picos de Europa holds more than a century of formal protection. In 1918, a national park was declared around the Lakes of Covadonga under the name Parque Nacional de la Montaña de Covadonga, marking the first step in Spain’s national park system.Spain’s first national park Over the twentieth century the protected area expanded, eventually covering the main massifs of the range and forming the current Picos de Europa National Park.
In 2003, UNESCO recognised the wider area as Picos de Europa Biosphere Reserve under the Man and the Biosphere Programme, highlighting the coexistence of traditional pastoral use and relatively undisturbed mountain ecosystems.biosphere reserve nomination in 2003 The park extends across eleven municipalities and remains one of the few national parks in Spain with inhabited areas inside its boundaries, where villages and farmsteads are part of the protected landscape.inhabited National Park
