Senda del Oso

The Senda del Oso is largely considered an easy trail, making it suitable for families, beginners, and cyclists of most levels. Its gentle gradients are a result of its origin as a former mining railway line, with inclines generally not exceeding 4%. While mostly smooth, some sections can be uneven, requiring basic cycling skills.

The trail primarily features a gravel path, with some sections also paved. It follows an old mining railway line, so you'll encounter numerous tunnels (which are usually illuminated but can be uneven inside) and bridges. The path is generally well-maintained and signposted, often bordered by a wooden fence for safety.

The Senda del Oso offers diverse scenery, including lush vegetation, dense forests, and views of gorges like Valdecerezales. A major highlight is the "Bear's Path" itself, named for the Cantabrian brown bears that live in a semi-freedom enclosure along the route near Proaza. You'll also pass by the Mirador del Portillo de Carro and enjoy a View of Embalse de la Requejada. The La Bárcena Watermill is another notable point of interest.

The trail can be enjoyed year-round, but the best times are generally during the spring and autumn months when the weather is mild and the natural scenery is at its most vibrant. Summer offers shaded sections, which are ideal during warmer months, but can also be busier. Winter riding is possible, but be prepared for colder temperatures and potentially wet conditions.
