Desfiladero de los Beyos is an amazing gorge located between the provinces of Leon in Castile and León and Asturias, in northern Spain. It’s one of the most scenic canyon roads of Spain.
The gorge is traversed by the twisty N625 road. It’s 16.6km (10.31 miles) long running north-south from Ceneya to Oseja de Sajambre. The road follows the natural course of Sella River, through one of the most extraordinary defiles in Europe.
The road is paved but narrow in some parts. It is characterized by the verticality of its walls and the narrowing of the valley produced by the erosion of Sella River. The notable features of this landscape include the upper valley of the River Sella, and the rock erosion caused by the action of the river, creating a gorge with steep walls that line the river. The road is a remarkable feat of engineering tracing the ancient contours of the Camino del Beyo, a 17th-century footpath.
