A legendary mountain pass in the Pyrenees. A crossing point between the Chistau and Benasque valleys, linking Sobrarbe and Ribagorza at an altitude of 2000m.

A true "refuge" for sight and taste. That cool drink watching the Lost Mountain is priceless

Although perhaps the most notable is its Romanesque parish church, expanded in the 16th century, the entire town is worth a walk through its steep streets flanked by houses with thick stone walls and slate roofs.

Access is via forest tracks in good condition. Obviously, to reach 2000m it takes a little time but the reward is worth it: the views are magnificent over the valleys and peaks at 360 degrees. A delight !

4x4 track in very good condition. The climb is long and fairly regular. The views change as you progress and motivate you to continue to the pass which offers a magnificent spectacle.

Castejón de Sos is a fairly large Ribagorza municipality, compared to the small population centers that exist in the surroundings. It has hotels, supermarkets, restaurants and a pharmacy. It is very close to the Ventamillo Gorge, an imposing canyon crossed by the Ésera River.
