Park in the car park near the Résidence Sère Clos Saint-Michel in Esquièze-Sère.
(S/E) From the car park, head to Avenue de Barège and follow it to the left. Cross the bridge over the Blastan and turn left onto Rue de Barège (D918) and stay on this street until you reach the town hall of Esterre.
(1) Walk about 100 m along the edge of the Route de Barèges, then take the path on the right that climbs through the woods towards Viella (signposted).
(2) At the church in Viella (inn on the left), climb to the top of the village via the street opposite (town hall on the right). At the EDF substation (car park), continue straight ahead on a carriage road, which soon becomes a path after the stream bed.
(3) Climb between the meadows. You will come out onto a road at the corner of a barn. Cut across it to join another road higher up. Turn left at the hangar and stay on this track for about 800 m.
(4) Leave the track for a marked secondary path on the right. Cut across a wider path further up and continue climbing to the carriage road you left below.
(5) Turn right onto the carriageway and follow it for about 600 m.
(6) Just after the Ruisseau d'Alet stream, leave the track and take a path that descends to the left, passing immediately under a barn, towards Betpouey (sign). It cuts through the middle of the meadows, then runs along the left bank of a stream to the village, which you cross. In the lower part of the village, take the access road on the right until you reach the D918.
(7) Cross the Route de Barèges with caution (no pedestrian crossing) and cross the Bastan via the footbridge opposite. Immediately after the bridge, turn right onto a path in a meadow towards a barn. The trail then climbs steeply into the forest, in two large hairpin bends, towards the village of Sers. This leads to a road.
(8) Follow the road that turns left towards the church in Sers, then join another road and follow it to the left.
(9) At the intersection of the fountains, go down a cobbled stairway between the houses on the left, then find the start of a horizontal grassy path on the right. After overlooking a meadow, it descends through a light wood. After a gate (close it behind you), you will reach an intersection of paths and continue to the right, crossing towards Viey.
(10) At the Viey wash house, walk straight towards the centre of the village along a balcony street. Then descend to the left of the church and town hall along a cobbled lane, cross a road and descend towards the bottom of the valley along a forest path opposite.
(11) At the bottom, take the bridge at the waste collection centre to rejoin the D918. Follow it to the right for 150 m , taking care.
(12) Go up to the left on the access road to Viella (D148).
(2) At the church, take the path on the right that you took on the way up to descend to Esterre.
(1) Continue to the car park near the Résidence Sère Clos Saint-Michel in Esquièze-Sère (S/E).
