An original and wild descent, for skiers able to navigate and read a map. Exceptional environment.

From the summit of the Petites Rousses tram (Vaujany sector), descend the gentle slope towards the North until a small basin then to push-off on your poles for several hundred meters. Pass the southern entry of Combe des Perrins and descend towards the north via a gentle slope until a first flat area. Go diagonally towards the west to reach the entry of the canyon (on the left) via more unrelenting slopes intersected with a second flat area. The entry is very narrow but the slope does not continue, giving you a chance to rest and little risk of falling except in hard snow in the spring.

At the outlet of the canyon you reach the Clos Grand piste.

Epaule de la Fare variant (more complex and exposed): Go past the entry of the canyon (on the left) and traverse horizontally towards the right until a large slope, descend skirting the rocks on your right then leave it traversing to the right above rock barriers until the Clos Grand piste.
