Departure from the Chevenne car park, located at the end of a road leading from the village of La Chapelle-d'Abondance.
Signposts are located at major intersections, as well as yellow arrow markers at intervals along the route.
(S/E) Head towards Col d'Ubine and Chalets de Mens, following the road and crossing a bridge over the Chevenne stream. Ignore a path on the left and continue straight ahead on a wide, gravelly mountain track.
(1) At the sign for "Chalets de Chevenne 1235 m", cross the Séchet stream via a wooden footbridge without railings and follow an alpine track uphill towards the Chalets de Mens. Further on, cross a stream at a ford and, at the fork that appears immediately, take the right-hand branch, which is less steep.
(2) At the sign for "Altitude 1320m", take thesecond path on the left towards Chalet de la Raille (red star on a small rock). The path is steep and winds through the woods. Once the slope levels out, the path opens onto a grassy valley. Cross this valley to reach the Chalet de la Raille.
(3) Continue along a wide path that descends towards the south-west and passes Chalet de Chez Trosset and then Chalet de Crébin. The path then turns sharply to the right, running between the mountain pastures (on the right) and the forest (on the left).
(4) The path turns sharply left and becomes a stony track that descends steeply to the car park at Le Sauvage (ignore several turnings on the left).
(5) At the car park, take a track on the right (west) that climbs 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 and sometimes very steep, winding its way through meadows and undergrowth to reach the base of the western ridge of Mont Chauffé. After a final steep climb, you will reach Col de La Plagne (cross).
(6) Turn right (north then east-north-east) towards the Chalets d'Ubine, on a path that rises gently at first and then levels out, running through the undergrowth or along the edge of a meadow. The path then descends towards Ubine (north-east), first through the undergrowth and then across pastures. Cross a stream, go around the Chapelle d'Ubine chapel on the right and reach the chalets of the same name.
(7) At the information board, turn right towards the Col d'Ubine. Pass the Amis de la Nature refuge on your right and climb up an alpine path, passing a cross on your left. Continue along the path and cross a few streams.
(8) Leave the path when it climbs towards Pointe de Lachau and take a fairly flat path on the right towards the clearly visible Col d'Ubine. Cross a stream near a group of spruce trees. Just below the pass, the slope becomes steeper: follow a few hairpin bends to reach the pass.
(9) Then take a path heading north-east towards the Chalets de Mens. Descend directly below Pointe de Lachau and reach the Chalets de Mens (large cross).
N.B. It was once possible to descend directly to Chevenne without passing through the Chalets de Mens (a route that still appears on the 1:25,000 IGN map). The corresponding path has in fact been erased and it would be unwise to attempt to follow this route, which is heavily overgrown with vegetation.
(10) Then turn right (south) towards the Chalets de Chevenne. Descend gently through the mountain pasture and then more steeply through the forest. Ford the Ruisseau de Séchet stream directly below Mont Chauffé, turn left and continue descending.
(2) Continue straight on towards Chevenne. Further on, cross the Séchet again.
(1) At the end of the footbridge, descend to the right and quickly reach the Chevenne car park (S/E).
