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.

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.

The Rigau path is one of the two ancient paths that go up the Benasque valley (the other, which runs along the eastern bank of the Ésera river, is the Ball path or French path).

The Cubera bridge, also known as the stone bridge, crosses the Ésera river, in the Benasque valley. This stone bridge, of probable Romanesque origin, is built with masonry rigs of irregular shapes. It has only one eye, with a semicircular arch, and its profile is that of an irregular donkey's back, since one slope is longer than the other. The bridge road is made of ashlar, including some small sidings.
