About Senda del Oso Natural Park

Senda del Oso Natural Park offers an exceptional outdoor experience through northern Spain’s lush Cantabrian Mountains, combining scenic trail exploration with opportunities to observe Cantabrian brown bears and diverse wildlife.

Wilderness Landscape & Natural Heritage

Senda del Oso Natural Park is a captivating protected natural area located in Asturias, northern Spain, known primarily for its scenic multi-use trail that spans approximately 50 kilometers through the verdant valleys of the Cantabrian Mountains. The park’s geography is distinguished by rolling hills, dense beech and oak forests, steep river valleys, and charming mountain villages. Ecologically, the park is a crucial habitat for the endangered Cantabrian brown bear, one of the rarest bear subspecies in Europe, as well as wolves, wild boars, chamois, and an array of bird species. The park’s name, “Path of the Bear,” reflects the importance of bear conservation in the region. Historically, the trail follows a disused railway line that once serviced regional mining and timber industries, now converted to a multi-use greenway for hikers, cyclists, and casual visitors. Key recreational opportunities center around hiking, mountain biking, and wildlife observation, with several bear observation hides equipped to view bears safely in their natural environment. The route also showcases several small villages such as Entrago and Proaza, where visitors can engage with local culture and Asturian gastronomy. Notable landmarks include restored railway tunnels, river crossings, and the Bear Interpretation Center located in Proaza, which provides educational exhibits about bear biology and conservation efforts. The park’s appeal lies in its accessibility, seamless blend of cultural and natural heritage, and unique wildlife encounters, attracting families, adventure travelers, and nature enthusiasts alike.
