The downhill by mountain bike on the North side can only be done by 2 people. At 4 points, you have to carry the bikes with one person below and one holding it above. Allow 1 hour to go from the pass to the Col du Cou. The approach from the South side via Champ Laitier is feasible without difficulty (path in the grass for hikers)

Crossing the Col du Freux is horrendous. The path leading to the hamlet of Sambuis is very steep, requiring pushing or even portaging for 600 meters.

Between the Enclave and the Montagne de Sous Dine you will find the Col de l'Enclave, a wild and isolated pass with excellent alpine trails crossing it. The pass is an ideal place to look out for local wildlife, particularly chamois and marmots.
