The starting point is in Le Levron. From there, follow the path that leads up towards the Col du Tronc pass (1,580m). There is then a climb towards La Crevasse (1,807m). Hikers are greeted at the summit by a magnificent 360° panoramic view that includes the Combins massif, the Catogne, the Pierre Avoi and the Grand Chavalard.
IMPORTANT: Do not approach the edge of the cliff!
Head back down towards the Col des Planches and return to the Col du Tronc via the forest path. From there, return to Le Levron via the same path you started on.
