Senda del Oso – Path of the Bear
The villages of Tuñón and Entrago, found south of Oviedo, are connected by the Senda del Oso, a popular trail running through the valley carved by the Trubia River. Formerly a track for mining trains, the trail has been converted for recreational use and has a lot to recommend it: rapids, tunnels, cliffs, fountains, villages and, yes, bears.
