A large circuit taking you up to the magnificent panorama from the summit of Le Cuchon before a return down to Ancelle and, in complete contrast, the plain of La Chaup, a light-filled and strangely flat basin in the midst of steep mounts.From the Libouse plateau, head for Sous-le-Bois-Fustier, then take the GR50 towards Serre Laguenia. Leave the GR50 and continue to the Prés Jaunes cabin, then to the summit of Le Cuchon. You then head for Ancelle through the Rouanne valley via Le Ranc and Simonde. Continue on to Oratoire, Le Peintre, Chabottes, Le Moulin, La Rase, Château Lombard and as far as Les Faix. 400m after Les Faix, you meet up with the GR50 again, on the right, and then continue to Champ Garaille. Leave the GR50 and return to Sous-le-Bois-Fustier and the Libouse plateau.
Libouse Plateau, Saint-Léger-les-Mélèzes
This trail leaves from the Libouze plateau, where there is already plenty to do, with picnic tables and a pond containing midwife toads and Alpine newts. At the summit of the Cuchon, an orientation table is a chance to revise the view: can you spot Le Vieux Chaillol or the Pic de Gleize?
From the RN 85, take the D14, then the D 944 towards Pont du Fossé/Orcières. At Chabottes Haute Plaine, follow the D113 to St Léger-les-Mélèzes.
