Unmarked route. Dirt tracks: 85%
(S/E) Take the road towards Saint Laurent church and turn right in front of the cemetery. At the end of Rue Eleonora Chedeville, turn left onto Allée des Maronniers and take the path that runs behind the château.
(1) Go through the metal gates at the animal crossing and enter the woods on the communal path that runs alongside the holiday cabins. At the crossroads, take the dirt track to the right of the large beech tree: plot 86 marks the entrance to the Montfort National Forest.
(2) At the "Quatre frères" (four brothers, a remarkable tree marked by the ONF), go down to the right towards the bottom of the valley, then follow the valley bottom to the left: you are now in the heart of the Petite Vallée. Then follow theGR® straight ahead at the foot of the hill that climbs northwards, keeping a good distance from the RD130.
(3) Just before reaching the tarmac road, turn right to climb into the forest via the bridle path, continuing straight ahead (orange markings).
(4) At the top, bear left and rejoin theGR®. At the crossroads, continue straight ahead, following the yellow markings for the Saint-Vincent route from the Saint-Vincent area, the ONF reception area 1 km away. At the end of the path, take the forest lane to the left until you reach the clearing.
(5) Turn right at the corner of plot 89 and continue straight ahead until you leave the national forest, where the boundary is marked by a barrier. Follow the valley between woods and meadows.
(6) At the end of Rue de la Houssaye (dead end), keep right and then at the next crossroads, take the path that descends to the right.
(7) At the bottom, turn right onto the road, then immediately right onto the path that is closed to motor vehicles. Go through the barrier: the path is private but open to walkers (be careful on hunting days on Sundays between late September and February). In the valley, turn left to go back up the hill.
(8) At the top, at the end of Impasse des Frénettes, follow the street to the right, then turn rightagain at Rue Cailloux to return to the town hall. Turn left to enter the grassy area behind the town hall or follow the gravel path along the edge of the property to reach the car park (S/E).
