FATMAP difficulty grade
These couloirs are serious and only for experienced skiers.
This line frequently avalanches in its entirety so, as well as making sure you don't set it off, you'll need to know that it hasn't already gone as otherwise you'll be skiing a lot of unpleasant debris at the bottom.
In the right conditions however, it offers excellent skiing.
Hike from the Tête de Balme chairlift to L'Arolette summit.
Traverse high round under the Croix de Fer to the col.
Descend into this steep and exciting couloir and follow it all the way to the valley floor.
A wild and adventurous line.
