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 !

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.
