From Lescun to Lhers via Chemin de Petraube

This moderate loop links the village of Lescun with the old path toward the Lhers plateau, following the Chemin de Petraube for a walk of about 8 km / 4.9 miles with roughly 300–350 m / 985–1,145 ft of ascent. The route is generally considered a half-day outing, with a typical walking time of around 3 hours 15 minutes, and it stays mostly on the northern side of the valley, where woodland gives useful shade in warm weather. The recorded start point at 42.933943, -0.634956 corresponds to the village square and war memorial in Lescun, 64490 Lescun, France. (visorando.com)

From the center of Lescun, the route heads south on Rue d’Espagne, briefly joins Route de Lanedert, then drops to the Pont du Moulin to cross the Gave de Lescun. After a short stretch on the D340, the old Chemin de Petraube branches off just below the road beside a gate. Farther on, the walk rejoins the road briefly, passes Ferme Rachou, then returns to the old path, crossing the Torrent de Labrénère above an EDF water intake before climbing through forest to the edge of the Lhers plateau, where it meets the GR10 for the return to Lescun. The highest point is about 1,041 m / 3,415 ft, and the lowest is about 808 m / 2,651 ft. (visorando.com)

What to expect on the trail

The first part is gentle and pastoral, with village lanes, a river crossing, and open views back toward Lescun. Once on the Chemin de Petraube, the character changes to an older, quieter mountain path with a more historic feel. This is not a high-alpine route, but it has enough climbing to feel like a proper mountain walk, especially as the path rises toward the plateau. The ascent is steady rather than relentless, making the medium difficulty rating a fair estimate for hikers with reasonable fitness. (visorando.com)

The woodland section is one of the defining features of the hike. It offers shade and a cooler microclimate, which is especially helpful in summer. The route then opens onto the Lhers plateau, where the landscape becomes broader and more pastoral, with the sense of moving from enclosed valley paths into upland grazing country. This transition is one of the highlights of the walk. The return on the GR10 adds a more established long-distance-trail feel before the descent back toward the bridge and village. (visorando.com)

One practical point: the first section of the old path can become overgrown with ferns and brambles, particularly in spring and early summer, so long trousers are a sensible choice. Even though the route is described as easy to follow overall, the Petraube path is noted as not being heavily signposted, so carrying the route in HiiKER is a smart precaution. (visorando.com)

Landmarks, scenery, and natural interest

Lescun sits in one of the most striking parts of the Aspe Valley, within the wider setting of the Cirque de Lescun, an area known for dramatic limestone peaks, pastoral plateaus, and traditional mountain settlements. Even on a relatively modest walk like this one, the surroundings carry that larger Pyrenean atmosphere. The nearby region is associated with famous summits and formations including the Ansabère area, Pic d’Anie, and the broader mountain amphitheater above the valley. (visorando.com)

Wildlife is a real point of interest here. The Cirque de Lescun area supports isards (Pyrenean chamois), marmots, and several large raptors, including the bearded vulture, griffon vulture, Egyptian vulture, and golden eagle. You are more likely to notice birds soaring overhead or hear activity around the forest edge than to have close mammal encounters, but the area is ecologically rich enough that binoculars are worth packing.

The Lhers sector is also tied closely to summer grazing lands, and the plateau remains part of an active pastoral landscape. Expect grazing animals in season and be prepared to pass through an environment shaped as much by herding as by wild nature. That pastoral presence is part of what gives the route its character.
