Departure from Le Sauvage (car park in the forest). At the upper exit of the village of Abondance (towards Châtel), take the small steep road on the left that leads to Le Mont. Pass the hamlet of Le Mont, turn right and park in the forest at Le Sauvage.
Directional signs are posted at major intersections.
(S/E) From the car park, take a track heading west towards the Col de La Plagne and the Chalets d'Autigny. Stay on this main track, heading generally west, roughly parallel to the high-voltage power line shown on the map (ignore three successive turnings on the left). The track is steep, sometimes very steep; it winds its way through meadows and undergrowth and joins the base of the Crête Ouest du Mont Chauffé. A final steep climb takes you to the Col de La Plagne (cross).
(1) Continue along the track, from where you can see the first chalets of Autigny. Descend slightly then climb again to reach the Chalets d'Autigny via a final steep section: the summit is then clearly visible to the north-west.
(2) Cross the group of chalets and continue along a path that climbs up the hillside through pastures, heading west-northwest. Go through a few gates that allow pedestrians to pass but not livestock. Go around a grove of spruce trees and pass under a high-voltage power line.
(3) Just after the signpost, turn right onto a steep path. Follow a few switchbacks to reach the Trois Croix. Continue in the same direction on the plateau and you will soon reach the summit (orientation table).
(4) Return via the same route to the place known as Le Sauvage (S/E).
