(S/E) Turn left to pass between the war memorial and L’Étape, the former hotel-restaurant in Blanot, now renamed Le Coing. It was here that, following a tip-off, five villagers who were members of the Resistance were arrested and deported on 23 January 1944. Their names, along with five others, are listed on the memorial. Stay on this wide path which winds its way uphill until you reach the Chemin du Faîtral and the signpost "La Roche".

(3) In the wide bend, at the foot of the vineyard, take the path that descends steeply to the left, marked by a brown symbol on a slanted square. Pass a waterhole to the left of a clearing and continue downhill, passing between houses to reach the Church of Saint-Maurice in Cortambert. At the Stop sign, cross the D117 at the pedestrian crossing and head down Rue de la Mairie to the left. Pass under an old fire hose reel. Head back up to the left.
(4) Turn right onto Rue de Roussot towards the cemetery and Varanges. Pass the cemetery. At the entrance to Varanges, continue left along the road. At the ‘Give Way’ sign, cross the junction and take the road opposite, turning immediately left towards a water feature consisting of a fountain with a drinking trough and a covered wash house dating from 1847. Walk up Rue des Colots, then continue left along Rue du Four à Chaux for about fifty metres.
(5) Follow the yellow-marked Ban Sacré route, which heads off to the right. At the end of the path, leave the marked route and turn left, then right onto the road. When you reach the Domaine des Sarilles, take the path on the right that leads uphill.
(6) When you reach the road, cross over to the opposite side and follow the Ban Sacré route which climbs towards Notre-Dame des Roches.

At the Mollard/Gros Jacques crossroads, continue straight on, still following theGR®. Do the same at the next junction a few dozen metres further on: the path is marked in red for mountain bikes. At Le Poirier au Prêtre (formerly Buisson du Fournil), pass a picnic area and cross the D146.
