A beautiful route of medium difficulty, requiring a good level to overcome the steep Sancerre slopes. You will enjoy passing through the Charnes woods, to Perrière cellars, to Clos du Roc, then back up to Sancerre, at the bottom of Tour des Fiefs, before going back down to the campsite via St Satur, its abbey church and its viaduct with 26 arches and 13 meters opening.
