Ancares Leoneses Biosphere Reserve

Ancares Leoneses Biosphere Reserve is a protected area in the El Bierzo region of northwestern Spain, encompassing several municipalities with mountain valleys, slopes, and river systems. The landscape contains high peaks, forested zones, and open meadows that create varying environments throughout the reserve.

This area received designation as a Biosphere Reserve from UNESCO in 2006, recognizing both its natural and cultural significance. The designation marks international acknowledgment of the mountain region's ecological and cultural importance to a broader community.

Traditional stone houses with thatched roofs called pallozas dot the landscape and show how people have adapted to mountain life for generations. These dwellings remain part of the living fabric of the region, reflecting how communities organized themselves within the valleys.

The reserve is best explored on foot using the network of walking paths that wind through valleys and across ridge lines. It helps to check weather conditions before visiting, as the mountain setting can bring rapid changes in conditions.

Centuries-old chestnut trees grow throughout parts of the reserve, shaping local land use and landscape character for generations. Some of these trees are so ancient and notable that they stand out as landmarks recognized by residents and visitors alike.
