(S/E) From the car park, continue along the road and, immediately after the hairpin bend, turn left into the mountain pasture (barrier), which gradually becomes a wooded area; climb up to the Col de la Fullie (1,338 m).
(1) Leave the path that arrives on the right and return to the mountain pasture (barrier). Leave the path on the right and climb up to the left along a barely marked trail to the Chalets de la Fullie.
(2) Pass between the buildings to reach theGR®96, then take it to the left. A path, then a stony trail, climb up through the forest. Return to the mountain pasture and a balcony trail, reaching a track (signposted "Sous Col de Cochette 1680m")
(3) Leave theGR® here, which descends into the valley, and follow the slightly uphill track to reach the Col de Cochette (1694m) a little higher up.
(4) From the pass, climb up the north-east ridge of Mont Colombier. A sign indicates that it takes 1 hour 15 minutes to reach the summit, with 350 m to climb. The path is steep, winding and well marked. This will take you to the summit at 2,043 m.
(5) Descend the west-northwest face of Mont Colombier towards the Col du Colombier, which is clearly visible from the summit. Cross a few steep sections with caution.
(6) From the pass, descend to the left to reach the Chalets de Rossane (1,738 m) in a few minutes.
(7) From the chalets, head left along the pastoral track to return to the Col de Cochette.
(4) Then follow the intersection and theGR®96.
(3) This time, take the track on the right to descend and arrive at an intersection.
(8) Stay on the track, ignoring a path that descends to the left (this is a shortcut, temporarily closed due to forestry work). Stay on the track and ignore the paths that branch off to the right to reach the Muret car park.
(9) Turn left onto the road and you will reach the vehicles in twenty minutes (S/E).
