Tricky passes
The balcony path above the cliffs, after the Col de la Brèche to the guards' hut, requires particular attention. Even if this path is wide enough, there is a risk of falling for around 300m, on ground that can be slippery after bad weather. The round-trip option is therefore more suitable for families.

Step by step
1. From the parking lot ("Baret" post, 1280 m), take the forest path towards Le Châtel (-> also called Bonnet de Calvin because of its characteristic shape). Cross the fir grove to join a forest track in a bend at the "Granges de Châtel" posts (1,390 m).
2. A few metres further on, take the path on the left, which climbs steadily. Rejoin the forest track and continue to its terminal platform. The trail continues with a few steep staircase sections and reaches the ridge at the "Le Châtel" post (1,890 m).
3. Reach the summit of Bonnet de Calvin to the right along a path through the meadow. It is marked by a milestone (1,937 m).
4. Go back down to the crossroads (point 3) and continue on to the orientation table.
5. Return by the same route as the outward journey.
