Park in the Col de Serre car park.
(S/E) At the southern end of the car park, take the path that leads to the road just next to the car park entrance, heading west. Follow the GR®® signs until otherwise indicated. At a barrier, leave the path and turn left onto a trail that joins the ridge. Continue on this trail in a south-south-west direction.
(1) Shortly after passing a gate, join the road at Burons d'Eylac. Follow it to the right. Further on, cut across a bend in the road via a steep path on the right. Return to the road, follow it to the left for a few metres, then take the path that climbs to the right and immediately turns north to continue in the same direction as the road below.
(2) At an intersection, leave theGR®® markings and follow the green markings to the left . This path quickly moves away from the road, climbing up to join the ridge.
(3) Climb up to the right, following the GR®® markings again, on the maintained path. As it climbs steeply, the path offers superb views of the ridge and the Puy de Peyre Arse. You will arrive at the summit (orientation table... and quite a few people).
(4) Descend via the very busy steps to reach the Pas de Peyrol, which is also very busy.
(5) Keep going in the same direction and cross the crossroads carefully! Take theGR®® marked trail that climbs behind the restaurant. Be careful! Only follow it for a few metres, then leave theGR®® and go through a gate on the right. Follow the fairly inconspicuous trail that crosses a meadow below the road. Go through a fence and you will come out onto the road. Continue along the path opposite and you will come to the intersection you passed on the way there.
(2) Find the GR®® signpost and follow it straight ahead. Then follow the same route as on the way there to reach the Col de Serre (S/E).
