This walk with varied scenery takes you to the gypsum pyramids, a curious geological feature of the region.
From Bretaye station, take the road down towards Villars for 50 m. Then take the path off to the left which passes under the Roc à l'Ours. Follow this pretty path to Ensex. Walk through the village and up the little path to the left to Col d'Encrène. Then take the path winding through the alders down to the Chemin de Perche. Head left and, just before Perche, take a right along the path to "Vy Boveyre". When you get to the little mountain road, head left and follow it until you arrive above Lake Les Chavonnes. Take the left path which takes you to the edge of the lake where you’ll find a charming restaurant. Then continue back to the path under the chairlift back to Bretaye.
