A stunning route that is maybe a bit more about the experience than lots of skiing.
It’s tricky to know when to do this line, to access it there is a long road up the mountainside that turns into a forest track. Too early in the season would make a really long slog up hill to get to the start of the route. In spring time and you can drive up to 1850M but will involve some walking with skis on you back and quite a lot of changing from skis to boots to get to the couloir.
From the parking at 1850M just after Moussière. Follow a footpath east past a building and towards the Cabana Ste-Marie, after the torrent du Beal Noir turn off the path and start to climb towards Les Crousas. From Les Crousas head east towards the Crête des Paréis. Once near the crête the South west couloir is easy to spot, climb it to the ridge.
When on the ridge head north a short way until the ridge become blocked and its hard to go higher.
Descend a steep slope down to a rock tower. From here head north across a steep bowl to a col that is the start of the North East Couloir. Ski the couloir, once out of the couloir start to traverse left (north) on a big open face. Once you hit the valley bottom, put your skins back on and climb back around to the Col de Moussière. From the col you can descent the valley to the parking. We travelled south to a ridge and descended that to the footpath we started from.
