Oscos-EO Region

The Río Eo, Oscos, and Terras de Burón Biosphere Reserve is a region shared by Asturias and Galicia where nature and culture have evolved together for centuries. The Eo River runs through this unique area, connecting the inland mountains with the estuary and the Cantabrian Sea through an extraordinary diversity of landscapes.

Native forests, river valleys, mountain ranges, traditional villages, estuaries, and the coastline form a mosaic of ecosystems of great ecological value. This natural wealth has led to significant conservation measures and the presence of iconic species such as the Atlantic salmon, the otter, the Iberian desman, the black woodpecker, and the wolf.

The Eo estuary is one of the Reserve’s most unique areas, essential for numerous waterfowl and migratory birds. In the mountainous areas, the moist forests are home to exceptional biodiversity, including rare species associated with well-preserved ecosystems.

Alongside these natural assets, the Reserve preserves a remarkable cultural heritage. The water mills, ironworks, and mills of Los Oscos reflect the historic relationship between its inhabitants and water and natural resources. In Castropol and Vegadeo, the “Indiana” architectural style serves as a reminder of the legacy left by emigration to the Americas. The Coastal Way of St. James also runs through this region, adding history and culture to a landscape of great beauty.

The Reserve offers numerous opportunities for ecotourism: hiking, wildlife and bird watching, exploring the ethnographic heritage, nature-based activities, and culinary experiences featuring local products such as veal, pork products, honey from Los Oscos, artisanal cheeses from Taramundi, cider, and oysters from the Eo estuary.

A destination to explore at a leisurely pace, discover the authenticity of rural life, and enjoy one of the best-preserved areas in northern Spain.
