Start by crossing the parking area at Hyelzas.
1) Before the houses, take the track on the left; at the crossroads turn left again going downhill. Before the barrier, the path veers left and joins an old mule track, which continues downhill to the D 996.
2) Turn right onto the D 996, towards Le Rozier, to the hamlet of Les Douzes.
3) Just before the restaurant, take the stairs uphill between the houses to the sanctuary dedicated to St Gervase.
4) After visiting the sanctuary (retrace your steps), take the path on the left onto a flat area. Continue straight ahead on the path that goes up the ravine of Les Bastides, then cross the ravine and go uphill to the D 63 road.
5) Turn right onto the road for 500 m to the gate, and take the track on the left. Go past the gate. At the first crossroads, take a path on the right that goes uphill to the hamlet of Les Bastides.
6) In the hamlet, take the road on the right downhill to the D 63. Cross the D 63 to take the path opposite, which goes downhill for a few metres, then uphill to a track leading to Hyelzas.
7) Go past the front of the Caussenard farm, then turn right, then left, then right again to return to the parking area.
