From Oloron-Sainte-Marie, head towards Lescun, then, after the Toyal factory, follow signs for Lhers; after the six hairpin bends, follow signs for Lescun; at the junction, go straight on towards Masousa-Ansabère, then pass the sign for Anapia-Lhurs on your right. Turn left onto a road that winds uphill; at the end, turn right towards Maison Salanoube and park at the cattle grid.
(S/E) Continue along the track; at the hairpin bend, leave the track (this will be the return route).
(1) Take the grassy track opposite and, following an almost flat path, join a track before the resurgence (noise).
(2) Follow this path, which passes above the Résurgence des Oueils, and continue to the dry stream bed.
(3) Make your way up the stream as best you can through scree, large boulders and dead trees. Caution: when you reach an impressive vertical drop (see photo), go round it on the left.
(4) Leave the main stream (vertical dry waterfall) and follow a less steep, more enclosed tributary until you are almost at the foot of a cliff.
(5) Turn right towards a beech wood, leading to a hanging valley, which takes you back to the main valley below Les Tourelles.
(6) Head up the valley keeping to the left; here there is more grass and less scree. Follow the tracks to the northern gap. Then head up to the left to a small pass, which allows you to bypass the rocky peak via the Lazerque slope. Continue along the steep ridge, keeping to the left; you may need to use your hands on the grassy and rocky sections. Reach Pic Bacqué.
(7) Descend the southern ridge, initially close to the cairns and tracks, then moving away from them – there are several possible routes – until you reach the southern breach.
(8) Descend to the left along the path; there is a slight climb to reach the ridge.
(9) Descend easily down the wide valley to the Cabanes d’Annès (water).
(10) Climb slightly, then descend the good but long path to the clearing at the Cabane de Couyède.
(11) Turn left and head down through the woods, cross the Ruisseau d’Annès, and follow its left bank to reach the original crossroads.
(1) Turn right and follow the route you took on the way there in the opposite direction to return to the car park near the Maison Salanoube (S/E).
