(1) Turn left onto Chemin de la Prairie.
(2) Turn right to enter a field, which you will skirt around on the inside via the path, then take a trail that curves up to the right. At the end of the path, turn right for 50 metres, then right again to cross the Malpige area. Join the old railway line.
(3) Continue to the right. After about 700 metres, leave the path on the right and continue on the path opposite. At the end of the path, go down to the crossroads on the right.
(4) Take the path diagonally to the left to walk along the right-hand side of the football pitch, then continue straight ahead on the path marked "autorisé aux piétons" (authorised for pedestrians). At the end of the path, walk a few metres up the old railway line and then continue straight ahead. At the end of the path, walk down a few metres to the right and then immediately turn left (picnic table).
(5) Cross the Orbrie road and follow Chemin des Champs Boyers opposite for about 150 metres. Turn left, then immediately right onto Allée des Champs Boyers. At the end of this road, continue along the path that rejoins the old railway line. Continue along this path, cross a wooden bridge over Chemin de l'Aulière and continue for 800 metres.
(6) Leave the path and follow the trail on the right just after the small uninhabited stone house. At the end of the trail, turn right onto Chemin du Fougeray. Then turn left onto a path after the vineyards (ignore the first path) and continue to the edge of the woods.
(7) Follow the path that enters the forest, staying close to the field for 300 metres, then enter the forest. Further on, cross a small footbridge over a stream (often dry), cross the Route Forestière du Cor de Chasse and take the path opposite. After about 700 m, take a path on the right, leaving another path that leads back. After about 300 m, cross the Allée du Palleneau and continue on the path opposite to reach the D99a.
(8) Turn right for 100 metres, then turn left onto the path on the left and quickly turn right onto the path that descends steeply, curving to the left and joining a stream. Follow the stream for a good hundred metres.
(9) Take a path on the right (not shown on the IGN map but present on OSM) which climbs steeply for about 30 metres, then continues to the Route Forestière de Doreau which descends towards the Mervent dam. Cross the road and follow the path opposite. After 450 metres, turn right onto a path which leads to a road.
(10) Turn right towards the Saint-Luc roundabout, then take a path on the left that leads to a stream.
(11) Take the path that branches off to the left, following this stream, and continue to the starting car park (S/E).
