Take the Contamines Montjoie ski lifts. From the summit of the Bûche Croisée chair lift descend to the South via a long traverse on the side until Grande Pierrière plateau where you put on skins. Go up this plateau by skirting the foot of the western face of Tête de la Cicle for 1500m until a poorly marked pass at 2283m. Descend towards the South (while pulling slightly to the right) to reach Croupe  de la Laissetire. Descend it until La Gitte (1665m).

Cross the torrent via bridge 1635 and climb to the east to the ruins of  La Planta (1784). Continue to the north and enter the gorges of the Sausse (summer trail more or less covered by sluffs). Go back up the dale towards the east until the Sausse chalets (1991m). The go completely north via a short steeper slope for 100m, then skirt the Croupe des Cavets on the right which leads to Col du Bonhomme (small shelter).

Descending the pass: Start to the north via a slight descent for a distance of 300m, then turn to the right to cross a short steep pitch. Via the flat area of Plan des Dames and a small slope under the Tumulus (2043) you reach Plan Jovet. Traverse to the left to reach an electric pylon. Descend behind it until the Balme chalets. Descend completely north via the trail which returns to La Rollaz and, via the Roman trail, the Notre de la Gorge parking lot. Via the road or the pedestrian path you can find the ski lift parking lot.

Climb variant via Col de la Fenêtre, without the ski lifts: - From Notre Dame de la Gorge (1210m) take the Roman path (often icy, crampons sometimes useful), traverse Nant Borrant hamlet to reach the flat area of La Rollaz (1530m). At the beginning of this plateau go right towards the SW (sign Les Prés, Col de la Fenêtre). Climb 50m in the meadow then  follow the track of the path which climbs in wood until the Prés chalets (1797m). Continue west until Plan de la Fenêtre (approximately 2000m) that you traverse towards the southwest (1km), to reach the foot of a corridor leading to Col de la Fenêtre. Go up 150m of this corridor to the pass (rather steep end). Descend the other side of the pass to the west crossing a small rock band. You reach the initial route on the Grande Pierrière.
