Take a tunnel under the motorway and follow a bridle path through the forest.
(2) At thefirst crossroads (forest plot no. 46), turn right at an acute angle to take a path that climbs through the undergrowth. At the next junction, turn right onto a wider path (the steep path opposite is an awkward shortcut). At the crossroads, take thefirst path on the left at an acute angle. At the next crossroads (plot no. 44), take the widest path on the far right (due south). Then ignore a path coming from the right.

You will come to a fenced-in meadow; turn right. Walk along the meadow on your left, and at the crossroads, continue straight ahead, still walking along the meadow. At the corner of the fence, turn right. You will come to a wider path; follow it to the right for about 100 metres.
(5) At the junction with a wide path on the right, take a narrower path on the left at an acute angle. Go through the tunnel under the A13 (keep your head down) and then take the footbridge over the railway line. At the end of the footbridge, turn left and walk along a pond on your right.
No markings
(6) At the next junction (forest barrier), continue straight ahead and follow a wide gravel path to the Lafayette Escadrille Memorial.

(7) Shortly before a tree with markings, turn right onto a path that is not very marked at first and climb gently. Pass a bench surrounded by a low wall on the left-hand side, then ignore a path on the right-hand side leading to a wooden footbridge. Continue climbing gently with houses on your right. Ignore a path coming from the left, immediately come out onto another path and follow it to the right.
Make a sharp left turn and continue climbing towards a large house located higher up. Ignore another path on the left and find the markings again at the foot of the large house. At the top of a staircase coming from the left (not shown on the map), turn right. Ignore a large gate on the right, pass between a playground on the left and an information panel on the right, and leave the park through a small gate.
Yellow markings
(8) Then turn left and, at the fork that appears immediately, follow the Allée des Haras to the right. Then take thefirst left. At the end, cross the Allée de la Marche and enter the Parc Boisé (chicane). Follow a path that winds along a fence and, at the corner of the fence, continue straight ahead. At a crossroads with cement paths, go straight ahead towards the Forêt de la Malmaison. Pass a car park on your right and turn left. At the next crossroads, turn right towards a prominent water tower. You will come to a street; follow it to the right for a few metres, then cross at the pedestrian crossing at the foot of the water tower. Follow Rue Victor Duret for a few metres.
(9) Then turn left onto a cement path and immediately turn right onto a stabilised path that runs alongside a football stadium on the left. Continue straight ahead on this path, which runs parallel to a street, ignoring all the access roads on the right, until you reach an information sign for the "Promenade des 4 Forêts". Cross Avenue de La Celle-Saint-Cloud, pass a small roundabout on your right and continue straight ahead on a footpath. You will come to a wide path, turn left and immediately come to a fork.
Red and white + yellow markings
Then take the tarmac lane on the right (forest barrier). At the next junction, turn left at an acute angle. Stay on the tarmac lane, which soon runs parallel to the lane you ignored at the fork. This will take you to an information board with a map of the Malmaison Forest.
(10) Turn left, leaving the sign on your right, cross the other tarmac lane, leave the car park entrance gate on your right and follow a path. Walk along the car park on your right, pass the picnic tables and wind your way through the undergrowth (in November 2019, you had to climb over a large fallen tree). At the end of the path, cross a stream, come out onto a wide path and follow it to the left.
Red and yellow markings
At a forest barrier, continue straight ahead along a street and follow theGRP® Ceinture Verte d'Ile-de-France (leave theGR®2on your right). At the stop sign, turn left.
