Park in the Col de Serre car park.
(S/E) At the southern end of the car park, take the path that leads onto the road right next to the car park entrance, heading west. Follow the GR®® markings unless otherwise indicated. At a barrier, leave the path and turn left onto a track that joins the ridge. Continue along this track in a general south-south-westerly direction.
(1) Shortly after passing a barrier, join the road at the Burons d’Eylac. Follow it to the right.
(2) Further on, cut across a bend in the road via a steep path to the right. Return to the road, follow it to the left for a few metres, then take the path which climbs to the right and immediately veers northwards to continue in the same direction as the road below.
(3) At a junction, leave theGR®® markings and follow the green markings to the left . This path quickly moves away from the road as it climbs to reach the ridge.
(4) Head up to the right, following the GR®® markings again, along the well-maintained path. As it climbs steeply, the path offers superb views of the ridge and the Puy de Peyre Arse. Reach the summit (orientation table … and quite a few people).
(5) Head back down via the very busy staircase to reach the Pas de Peyrol, which is also very busy.
(6) Keep heading in the same direction and cross the junction with care! Then take theGR®® marked path which climbs up behind the restaurant. Caution! Follow it for just a few metres, then leave theGR®® to go through a gate on the right. Follow this fairly inconspicuous path which crosses a meadow, below the road. Go through a fence and you’ll come out onto the road. Continue along the path opposite, then you’ll reach a junction you’ve already passed on the way there.
(3) Join the GR®® markings again and follow them straight on. Then follow the same route as on the way there to reach the Col de Serre (S/E).
