Great descent with lots of bends and a magnificent panorama. The climb back up to the plateau is less fun but the descent is well worth it.

A beautiful green plain with a meandering river through the lowest point. The GR54 trail is relatively busy, while the other paths are quieter. There's a parking lot with a public restroom at the top.

This link trail connects the Oz 3300 resort and the hamlet of Sardonne. It also serves as a playground for downhill mountain bikers during the Mégavalanche event. Imagine them hurtling down the slope at full speed. In the middle of the forest, it is sometimes possible to observe the lake du Verney.
