(S/E) From the car park, take Rue de la République on the left, then turn left at the war memorial. Take Rue Prélot on the right, pass in front of the town hall and go straight up through the vineyards.
(1) At the crossroads, continue straight ahead towards the vineyard lodge. When you reach the edge of the woods, turn left and walk to the vineyard lodge.
(2) At the crossroads, turn left. The path zigzags through the vineyards without really changing direction. It joins the woods (yellow markings). Continue along the edge of the woods.
(3) When you reach a real crossroads, take the recently renovated (and very uneven) path on the right that enters the woods. When you reach the edge of the plateau, turn left and follow the red hand-made signs that lead to Pierre Saint-Mamert. Without the app, it will be difficult to find it here.
(4) At Pierre Saint-Mamert, take a break and return to the previous fork.
(3) Continue to the right, along the edge of the woods. After a while, the path turns left and away from the woods towards the village of Saint-Martin. Walk to the first houses.
(5) Take the first proper path on the right, after the first lamppost. You are now on the CBR trail. Continue in the same direction until you reach the Mont Bayen road.
(6) Cross the D22 and continue straight ahead. Continue on the CBR, which is circular in the forest.
(7) Cross the D36 and continue straight ahead. Walk through the woods to the housing estate.
(8) Before the first house in the housing estate, turn left, passing in front of a rock. Take the grassy path that descends along the housing estate. This path then runs alongside the wall of Parc du Sourdon. Walk to the road.
(9) You can stop at Parc du Sourdon, the entrance to which is 100 metres on the right.
Turn left and take the road (Avenue de Paris) that descends towards the village. Pass the football field, then the wash house, and walk to the town hall square.
(10) Cross over and take Rue Tour Nicole opposite, which climbs between the houses and then the gardens. Walk to the Vertus road (D36), cross over and continue along the path opposite. When you reach a wider path, turn left.
(11) At the crossroads in the vineyards, turn right (PR® signposted). Walk to Brugny.
(12) At the wash house, turn opposite, pass in front of the castle entrance, then walk 300 m and turn left onto the small path (white marker).
(13) Continue to the left, passing in front of the abandoned farm and the equestrian facilities. When you reach the D951, continue to the pedestrian crossing and cross.
(14) Take the first right and enter Vaudancourt. Continue straight ahead, passing the wash house and fountain. Continue in the same direction along the path that runs alongside the vineyards. Stay in this direction and walk along the path through the vineyards to Chavot Church.
(15) Turn left onto the road that descends towards Moussy.
(16) Carefully cross the dual carriageway (D951). Continue straight ahead. Walk to the car park (S/E).
