The route begins with a gentle climb on the red Les Rochassons trail, then forks right into the heart of the forest, offering some breathtaking views over the valley.
This is a climb without conversions, with several technical sections on the first part. After passing through dense forest, you reach more open clearings before reaching the finish at Plaine Dranse. The descent is then made via the red piste of Les Rochassons or the green piste of La Belette.
The last descent must be made before 4.30pm.
Rather difficult itinerary.
