Heading towards Saint-Lary-Soulan, at the exit of Guchen, follow the signs for Vielle Aure via the D19. Pass the Le Lustou campsite and the Chapelle d'Agos, continue for about 500 m and park in a small car park on the right at the Croix de Housdarou, where there is also a picnic table.
(S/E) Take the path that climbs to the left of the road when coming from Vielle-Aure.
(1) After 150 m, at the fork, turn left and pass the slate quarry. The winding path is steep.
(2) Follow theGR®105on the left (red and white markings) and, at the first fork, leave theGR® and follow the path that climbs up to the right. Ignore the paths coming from the left and continue climbing through the woods. Pass a first barn, then two more.
(3) At the edge of the woods, you will come to the summer pastures.
(4) After two barns, turn right, then right again between the barns at the fork that follows.
(5) Pass a watering trough and continue towards the ridge (north-east).
(6) Follow the ridge to the left, towards the south-west, pass the summit near the Granges de Grascouéou and continue west-south-west along the ridge.
(7) At the signpost, turn left (south-east) and descend along a fence. Ignore a path on the right and, further on, a perpendicular path.
(8) When you reach a crossroads, take the track on the left that climbs up to the barns.
(4) Then take the same path you took on the way there to return to the car park (S/E).
. We got a little lost on the ridge when we had to follow the ridge to the left, as the path disappears a little in the grass, but thanks to the GPS track we were able to find our way back. We descended via the GR10 to Vielle-Aure to add some variety to the return journey
