(S/E) From the car park at the entrance to the village coming from Yenne, take the street that runs alongside the Portout Canal.
Turn right as you pass a square, then left and immediately right.
(1) Then go up the steep Rue du Moulin, which passes close to the Moulin de Chanaz. At a hairpin bend in the road, take a path that is sometimes equipped with steps. Go up the path to reach the vineyard road.
(2) Turn left and head east on this road. It continues as Rue de Pierre Noire, which itself continues as a grassy path.
(3) The path turns into a trail that climbs up the cliff, with a 50-metre cable passage allowing you to cross the ledge.
The trail then becomes a path again as it emerges above the cliff and gradually heads south.
Make a round trip to the viewpoint on the right, a little way off the path. Continue south along the path, which begins to descend.
(4) Join a winding road. Shortcuts allow you to cut across these.
(5) When you reach the first houses, descend to the right via Route des Puits, cross the Couloir, then reach Praille. Turn right at the bottom of the descent and rejoin the ascent route.
Turn left and rejoin the intersection passed on the way up.
(2) Descend into the village via Route de Chênes and stroll through the narrow streets before returning to the canal and the car park (S/E).
