Approach :
To get to the Granger lane, from Plan Fournier (1700m) towards La Cave, Fontaine Froide, or through the refuge of the Grand Bec. The track begins at 50m from the lowest point of the S edge.

Ascension :
The route follows the ridge to remain all the length in the rock by avoiding some easy parts type fallen rocks and which could serve as escape.
12 lengthes between 30 and 50m of level 2 to 5b lead to an abseiling of 25m.
The 2 lengthes (50 and 20m) before the abseiling are quite sustainded but well equipped (peaks, plaques). At the foot of the abseiling, go back up to a small corridor of 20m leading to a small pass (2995m approximately). The way continues on a 4 lengthes equipped spaced out until approximately 3100m.
It is possible then to cross on the left to join the ridge N or to continue on approximately 200m straight by following the rocky difficulties of the edge which leads towards a monolith in the direction of the summit via the ridge N (see existing rundown). Anticipate protection in this case (straighteners, straps and possibly pitons).

Descent :
At the exit of the itinerary, several possibilities:
• Descend the N ridge to 3140m and then descend a steep hallway (40°) leading to the morraine on Froide Fountain side. Then reach Plan Fournier by La Cave
Overall running time: approximately 8h.
• Merge onto the top by the north ridge. Cross through the ridge leading to the Pointe du Vallonnet. Descend the glacier de la Vuzelle to reach the refuge of Grand Bec and Plan Fournier.
• From the top reach the Plan des gouilles by the glacier of Troquérou.

After the abseiling and a climb of 20m, at the small pass (2995m), an escape is possible by a succession of abseilings of 25m or a de-escalation.
This makes it possible to reach the moraine of the old glacier of the Grand Bec.
Four platelets in place.

• Glacier safety equipment if descent on Troquerou Glacier or Vuzelle Glacier
• Sectioners, straps, possibly a few pitons to complete the existing protections and parts not equipped.
• For descent by Troquérou or Glacier de la Vuzelle: spike piolet.
• If descent directly through the ridge N, depending on the season and persistent snow, spikes and piolet are required.
• In all cases, mountaineering shoes are preferred. climbing shoes are not required.
• 50m single rope
