Second edition of this climbing book of the D'Ossau valley, one of the most touristic valleys in the French Pyrenees and with a mountain that is a symbol of the Pyrenees, both for climbers, mountaineers and hikers. Its silhouette impresses from all places where we can admire it.

14 years have passed between one guide and another and some new developments appear on the scene, both in sports and in long routes.Luis Alfonso has selected both itineraries and walls or sports areas of some interest.

Many of the itineraries in this guide have been opened from below and you are unequipped or semi-equipped, so you should take extreme caution and not venture into them if you are not above the level suggested by the degrees of difficulty.
