Senda del Oso
About
The Senda del Oso, meaning "Bear’s Path", is a 50‑kilometre rail‑trail that meanders through the verdant hills of northern Asturias, Spain. The trail follows the former mining railway that operated until 1963, linking the villages of Entragu and Santa Marina to Trubia, just north of the city of Oviedo. As travellers wind along the path, they experience a striking blend of pine forests, riverbanks of the Gándara, and sweeping vistas of the Cantabrian Mountains. The pathway has been upgraded in recent years, receiving a €306,000 investment in 2023 that improved signage, pavement, and safety railings, ensuring a reliable and secure experience for hikers and cyclists alike. The Senda del Oso appeals to outdoor enthusiasts who relish a moderately challenging trek combined with the thrill of discovering one of the last brown bear habitats in Spain. Whether you are planning a half‑day bike ride, a full‑day hike, or a week‑long exploration, the trail provides a versatile escape into nature that showcases Asturias’ natural beauty, historical heritage, and wildlife diversity.
