No advanced piste guide worth its salt would fail to mention these two legendary itineraries.
Chassoure-Tortin
The itinerary starts at the Col de Chassoure, where the Lac des Vaux triple chair and the Chassoure eight-person gondola meet.
From there, you can either drop straight in and tackle the moguls down the “wall”, or traverse towards the right along the face and drop in wherever suits you. Traversing is often worthwhile as the slope tends to be less bumpy the further you go, but be careful when doing so as the traverse can get quite rutted out and catching an edge or making a mistake here could result in an uncontrollable fall due to the slope inclination. From the bottom of the face, the run funnels to the right onto a flat cat-track, which eventually winds its way down to the bottom of the Chassoure gondola. Alternatively, you can drop off towards the right and follow the lift line to the bottom through a beautiful (but quite flat) landscape.
Mont Gelé
Although the skiing possibilities off Mont-Gelé’s summit are endless, two official 'Mont-Gelé' itineraries do exist:
For the south face descent, drop in on the right as you exit the cable car at the summit. On this first pitch, make your way diagonally left to avoid the impassable rock bands below. From the choke point, the face opens up in a big open bowl which continues all the way down towards the bottom of La Chaux. You can either continue straight (and eventually meet up with the Col des Gentianes-La Chaux red run), or progressively cut diagonally right to finish up on the La Chaux 2 blue run.
For the backside descent, go straight ahead as you exit the cable car at the summit. This will naturally take you left around to the back of the mountain, from where you can pretty much drop in wherever suits you. After a long, moderately graded descent, the slope inclination mellows out and the tracks funnel into a line which eventually gets quite flat, so try and keep your speed up to avoid pushing too much. From this point, you’re essentially on the final portion of the “Stairway to Heaven” off-piste run.
