On the west face of the Crête du Raisin and the Rocher du Raisin there are lots of lines and options some already described in this guide and some you will be able to choose when there. This one is an interesting line with two short couloirs and some amazing skiing.
From the parking cross the bridge and descend down a ski du fond track. Bearing off right climb through the trees and cross the ski du fond track a few times. Head to the valley of the Torrent de Creuzet, once in this valley climb through the trees following the torrent. As the trees thin out you see a tightening of the valley in front of you, head to it and climb up the steep slopes. When you get to the flatter section turn right (west) go through thin trees towards the Rocher du Raisin. After leaving the trees there is a short steep climb to a flatter area followed by a longer steep climb to the summit ridge.
Once on the ridge traverse south a short way to the top of the couloir.
Descent
Ski the couloir, as the couloir ends you have two options:
1) keep in the fall line of the couloir (SE) and ski down to the valley floor, from here you can make you way back down through the trees the way you came up.
2) At the bottom of the couloir when it opens up turn left and ski the east face almost until it flatterns out. Then travers north above a rocky outcrop and then you will find a second couloir. Ski the second couloir and then turn left (north) again on to the open slopes. Ski these down in to the trees and the end of the valley.
For both options as you come to the end of the valley you will meet a ski du fond track. You can follow it skiers right down hill at a sharp right hand bend you need to turn off to make it back to the parking. If you miss the turn off it will take you away from the parking.
