GRP® Tour of the Ossau Valley – Stage Col d'Aubisque – Gourette – Eaux-Bonnes

From the parking area, take the track to the right just before descending towards the Soulor pass. Below the TV relay station, take a path to the right along the hillside. Reach the ridge and follow it, bearing right. Pass the Col de Casteix pass and continue along the ridge. 0h30 Turn left, leaving the ridge for a path that traverses the hillside. 1h At the Col d'Arbaze pass, descend into a small valley. At a flat area, descend to the right. 1h20 On the right, take the path that climbs uphill. Pass a small hill, descend, then turn right. Join the GR®10 trail and climb. 2h At the Col de Tortes pass, descend following the path. 2h30 On the left, take the flat path. Then descend in switchbacks. 2h40 Take the track to the right and then descend in switchbacks to a large parking area. Go down the street to the right, then at the second bend, turn left. At the Gourette house, head back up towards the ski area, crossing the Place Sarrière. Take the path passing in front of "La boule de neige". Go up for approximately 700m.

3:20 At the first hairpin bend, turn right then left, climbing to the summit of Bois Noir. Descend and at a small pond, turn right onto the ski slope, which you will leave again 100m further on. Ascend the path to the right until you reach another track, near the mountain restaurant. 4:20 Turn right. At the retention basin, climb to the left for 150m then take the path to the right heading west.

4:30 am On the right, take a path that traverses the slope. Cross an avalanche gully and follow the path to the Bouy plateau, which you skirt to the left, staying at the same level (where you'll also find the charming little restored shepherd's hut that shares the plateau's name). After this point, the hike is mostly shaded. A pleasant option for hot days. 5:00 am At the pass, descend into the woods. Join a track and follow it downhill. The path will end on a forest track that runs alongside the Sourde stream, which is dry in summer. Upon reaching the road, you will pass the church and the thermal spa; continue downhill to the Darralde garden in the center of Eaux-Bonnes.
