Climb: From Serraz (1021m, start of the chair lift) go up the clear ski piste until Cuvy (alt 1700m). You can also start from the place called the Lérot, above Envers, in the event of insufficient snow cover. Continue the piste of the red ski hats. At the arrival of the chair lift, continue the piste, until the arrival of the Les Grangettes ski lift.

Climb a scoop in the alignment of the ski lift, then diagonally to the south (at the side) while always remaining under Tête Rouge to return to the pistes (descent of 20m).  Follow the scoops which lead to the summit of the La Forclaz ski lift. Climb a small pass above the arrival. You reach La Forclaz pass by a traverse towards the left. (2374m). Climb 20m of the face of the pass, then traverse a scoop towards SSW until the altitude of 2430m. Go up the slopes towards the west (micro reliefs can be avalanchous). Then a well marked scoop which climbs to the secondary summit of the Grand Mont (2633m). Return a few meters to reach the pass of the secondary summit and easily reach the summit.

Descent: - It is possible to descend by the same route. - Descend via the northern scoop until Serraz: From the summit, descend a gentle slope NE until a throat depending on the snow conditions: either traverse on the left to reach the full slope if the snow is stable, or descend a small corridor on the right partly protected by rocky spurs. The follow the northern scoop until Lac Cornu and then Lac Seston. Descend on the left of the main talweg, to reach a flat area above the Lac Tournant (careful of  the micro reliefs). Traverse the flat area of the lake (2002m), then pass to the left bank of outlet to follow the summer trail, which makes it possible via a hook on the left to more easily reach the dale (often powdery) of the Grand Mont stream. When it narrows, pass on the left bank in the sea buckthorns a sometimes tedious ski trail, with a steep pitch of 20m where it is sometimes necessary to remove your skis depending on the snow cover. At the end of the dale you return to the forest track at point 1543m, and follow it to Chomais. The connection boulevard (ski piste) makes it possible to reach Serraz. Descent variant: from Lac Tournant, climb to the NE until the pass located under the point 2073m and descend the scoops to reach the forest track and point 1543m.
