Grand Mont d'Arêches: Combe Nord via Lac Tournant

Climb: From Quefins, after having traversed the Perches ski piste, follow the forest track near spot elevation 1338m, to spot elevation 1543m (turn facing a boxed in narrow part). Go up the left bank of the narrow part, encumbered by sea buckthorn, sometimes tedious in the event of insufficient snow cover. Go up a small steeper slope, continue following the narrow part until it widens (1750m).

At the altitude 1870m, you arrive at a "bridle": go up the right branch (steep but short section). At the flat area, go up completely to the east following the summer trail to pass the steeper slope leading to Lac Tournant. Traverse the plateau, then to go up the opposite slopes at the east steep part to reach a flat area dominating the corrie of Lac Tournant. Climb back up the scoops to the east-south-east until the outflow of Lac Seston. Be careful of the avalanchous micro reliefs.

Continue southeast in the direction of Lac Cornu, that you pass on the right to go up the large northeastern slope which dominates it. You arrive at a flat area with a steeper slope above it which is the main difficulty of this route. This slope is inclined at 35° over 80m of height and can be plated: it is advisable to approach it with caution. It can be climbed with skins in good conditions. You can also go up in crampons directly towards the pass which dominates it (less exposed to the avalanches). Then there is a slightly inclined slope which leads west-south-west directly to the summit. It takes 3h30 to 4h.

Descent: You descend by the same route. It takes 1h to 1h30. The 80m can be avoided by going right under the colluvium which dominates it, a narrow corridor partly protected by rocky spurs.

Descent variant: at Lac Tournant, go up northeast 50m of HD until the pass located under the 2073m summit. Descend the northeast scoops to reach the forest track and spot elevation 1543m.
