On the road between Luz-Saint-Sauveur and the Col du Tourmalet, stop at Barèges. After the double hairpin bend at the entrance to the village, drive for about 200 m and, on the left, just after the Hubert Reeves school, enter the public car park marked “Résidence de l’Ayré et HLM”, just before a large building with a timber-clad façade.
(S/E) Follow the course of the Bastan upstream along the footpath beside the stream.
(1) At the entrance to the footbridge crossing the stream, a large sign marks the start of the walks, theGR®® 10, and a beginner’s drawing trail. Cross the footbridge, then turn left onto theGR®® 10.
(2) Ignore the return path on the right and continue along theGR®. About thirty metres further on, you can see on the right, slightly off the path, a memorial stone in honour of the ALAT soldiers who died in the line of duty. Continue along theGR®® overlooking the Bastan valley.
(3) Continue straight on to the end of the path, where you will find a campsite and a rocky summit topped by the Cross of Saint Justin and a small chapel.
(4) After exploring the site and admiring the view, retrace your steps along the path for about 200 m.
(3) Leave theGR®® and take the path that climbs gently to the left (a variant ofthe GR®®10) and further on meets a track coming from the opposite direction, which descends towards a hamlet down to the right.
(5) Follow this track straight on, continuing along the path.
(6) In a sharp right-hand bend, the road crosses a stream via a concrete ford. At the bend, turn right onto the path descending southwards, more or less following the stream. After several long hairpin bends, the path moves away from the stream and crosses another path.
(7) Keep left to return to the stream, which you will soon cross before descending steeply alongside it. Join the GR®®again.
(2) Follow it to the left and return to the footbridge over the Bastan.
(1) After crossing the footbridge in the opposite direction, return to the car park by following the path along the stream (S/E).
