The Chemin de la Mature
is a wonderful walk carved in the stonewall over a ravine at North of Port de Somport in the area of Lescun. The trailhead is signaled in the village of Etsaut
to Parking of Lebers. The walk-up is short and it don't climb any peak and for this reason I think that's the best way to show this interesting route. Another option is to write a route in the area-range but it's not necessary to know more because the itinerary is easy to follow (you must walk over the ravine and you don't walk into ravine... it's easy to understand,... it's a joke, but after a recent snowfall or with storm it's advisable don't walk because the route is exposed and the fall is long to the ravine).
The origin of chemin: it was carved to use the wood of the pines for the ships of French Army in the XVIIIth Century.
A good option is to walk from the exit of chemin to the cross of GR-10 returning across the Col of Arras (1300m) to the trailhead. The col is a great observatory to the Aspe's massif.
To climb some peak you has the Pic Ayous (2228m) but the slope to gain is more than 1600m and it's hard.
Time (total): only chemin de la Mature 1h30m; with return across Col d'Arras 3h30m.
