Parking at the Saint-Cucufa car park, near the lake and the forest house of the same name, at the junction between Route du Pré Boni and Route de Versailles, in the Malmaison forest.
No signposts
(S/E) From the car park, return to the Route de Versailles, with the sign for the Route du Pré Boni opposite. Cross the Route de Versailles and immediately turn left onto a path parallel to this road, which starts at the foot of the "Impasse - Rappel" sign (wooden steps then chicane). The path quickly leaves the road and starts to climb. Ignore the steep paths on the right and continue to a car park.
Red and yellow markings
At the end of the car park (at the entrance for motorists), turn right past a forest barrier and continue along a tarmac path, with the forest on your right and a hedge then a fence on your left. Ignore a path on the right (plot no. 57) and, a few metres further on, turn right (plots nos. 58 and 57). The path descends and, at a fork (plot no. 54), take the narrower path on the left. At the next crossroads (plot no. 53), turn left and go uphill. Ignore a path on the left and, immediately after, turn right at a right angle and go downhill.
No signposts
(1) At the T-junction at the bottom of the descent, leave theGRP® trail going down to the right towards a forest barrier and turn left (horseshoe painted on a tree). At the fork immediately following, take the path on the right that passes at the foot of an isolated house on the right. Pass plot number 63 and, at the next junction, turn right onto a wider path that descends. Ignore a path that branches off to the left, pass an ONF information sign and arrive at a T-junction (signposted "Route Forestière de la Côte Raide").
Red and white markings
(2) Turn left and go past a forest barrier. At the corner of a house (No. 41), turn right. Look for a kind of ring at the end of a street and take the left-hand lane, then immediately turn left onto a path in the woods (plot No. 63, sign further on). At a T-junction, turn right. At the foot of a sign for "Hameau de la Juchère", turn right into a small street (the "No Entry" sign only applies to the property beyond the fence). At the next junction, turn left into Chemin des Vignes (two "No Entry" signs).
No signposts
Leave theGR® trail and continue straight ahead on Chemin des Vignes, then turn right onto Chemin du Bois Béranger. At the end of the street, turn left onto Chemin des Cormaillons. After a few metres, opposite a green gate, turn right between some stone blocks to reach the Gallicourts viewpoint (three information posts).
(3) Go down the grassy path that starts on the right, at the foot of the middle information post. At the bottom of the short descent (picnic tables), turn left and then immediately right after the last table, with a wasteland on your left and a lawn dotted with fruit trees on your right.
Red and yellow markings
At a crossroads (two benches on the right, information post no. 16 "Prairies" on the left), continue straight ahead downhill with the GRP®. Cross a road and continue towards the Forêt de la Malmaison (sign). Shortly before another road, turn left to stay on the path. Return to this road, cross it and continue through the undergrowth (plot no. 73). Reach the Porte de Rueil car park and cross it.
Yellow markings
(4) Cross the road and take a path that veers to the right. At a fork that appears very quickly, leave theGRP® trail on your right and turn left. At the next fork, turn right. Ignore a path that crosses diagonally and, immediately after, at a fork, take the narrow path on the left (plot no. 88). An arrow indicates an upcoming right turn and you will reach a junction with a bridle path (tree with a yellow marker in the middle): continue straight ahead and ignore the marker on the right. Immediately after, cross a road diagonally to the left and follow the path that climbs steeply, heading east-northeast.
(5) You will come out onto a road (plot no. 6) and follow it to the right for a few metres (ignore the yellow marker opposite). Then turn right onto a path that descends. At the bottom of the descent, at a crossroads, continue straight ahead on a pleasant sandy path which is also a bridle path. Ignore the paths branching off to the right and left.
At the junction at the boundary between plots 9 and 10, continue straight ahead. At the next crossroads, continue straight ahead and then, at a fork, take the right-hand path. At the next crossroads (plot no. 32), take the path furthest to the right. Ignore a path leading off to the right and, at the next crossroads, make a zigzag turn left-right (plots nos. 82 and 81).
(6) After about 150m, turn right between plots nos. 33 and 34. Head north, descending slightly, ignoring all paths (usually less marked) on the left or right. At the bottom of the descent, turn left, keeping parallel to a sunken path lower down on your right. Leave a bridle path on your left and turn right, descending to reach a forest road which you cross (map) to reach the edge of the Etang de Saint-Cucufa.
No signposts
(7) Turn left and follow the pond on your right. At the end of the pond, turn right onto the small bridge. Then turn right, still following the pond. After a few metres, with a small lawn on your left and a signpost opposite (no. 864), take a path on the left. Pass the Maison Forestière de Saint-Cucufa on your left and continue along a narrow, shaded path (bench on the left). Cross a tarmac road, continue along the path and return to the starting point (S/E).
