To get to the starting point, head towards Phalempin (59133) and park in the station car park on Rue Léon Blum
(S/E). Head north, then turn right onto Avenue Péchon and cross the railway line at the level crossing. Stay on Avenue Péchon and follow the GR®121B (red and white markings). Take the bridge over the A1 motorway and continue for another 150 metres on the D62a.
Please note that the D62a is lined with wooden safety barriers at this point. Stay well behind this barrier.
(1) At the end of the left-hand barrier, leave the D62a and take a path heading north-east (please note that there are no GR® markings indicating the change of direction; you will find these red and white markings a little further on, painted on the trees).
Stay on this GR® for 5.8 km, following the markings carefully (at each intersection and change of direction, the markings are clearly visible and crossed out with a yellow cross on the paths to be avoided).
(2) At the edge of the woods, you will find yourself on a tarmac forest road called Drève Goffart. Head east for 110 metres until you reach a barrier. At the barrier, continue south-east along Rue du Pluich. Cross the hamlet called Le Plouich and continue in this direction for 350 metres until you reach a riding centre.
(3) Then turn left (north-east) onto the Wagriaux country lane. Go through the barrier and continue in this direction for 600 metres until you reach the edge of the woods on the tarmac Genne lane.
(4) Turn right towards the south-east onto Rue de Neuville, which passes through fields, leaving theGR® 121B on your left to follow thePR® (yellow markings). Continue until you reach the junction with the D8.
(5) At the intersection with the D8, turn right and then immediately left onto the path located at the exit sign for the hamlet of Le Petit Attiches.
Please note that from here on, the yellow markings are completely random or even non-existent.
Follow this path along the edge of the woods with the yellow markings until you reach a crossroads in a clearing.
(6) At the clearing, follow the path on the left, which is blocked by a sign prohibiting access to horse riders. Continue along this path following the edge of the woods for 1.5 km. Be careful, the path is quite muddy and there are no more markings from the clearing onwards, but as there is only one path, you cannot go wrong.
(7) At the end of the path, when you start to see buildings in the distance, turn south-west at a hairpin bend to join the tarmac road called Drève d'Attiches.
On the Drève d'Attiche forest road, head north-west and continue in this direction for 900 metres.
(8) Turn left towards the south-west. (Please note that there are no signs indicating this path, but it is the only path with a sign indicating that dogs must be kept on a leash, as you are passing through a tree-top adventure park).
Continue until you reach the first equipment of the Chloro-Fil tree-top adventure park. White signs visible from a distance will show you the way to the reception area. Follow these signs to reach the park entrance and then a roundabout: the Leu Pindu roundabout. Pass to the right of the Leu Pindu restaurant (not without noticing the façade and the legend surrounding the place).
(9) Take the forest path on the left of the D8, which indicates the entrance to the Phalempin National Forest (a barrier prevents vehicle access). Continue straight ahead in a north-westerly direction to pass in front of the Château de l'Ermitage. Continue straight ahead on the path, still following the north-westerly direction. Pass between the ponds visible on either side of the path to reach a crossroads with the Dréve Noire. Cross the crossroads and continue north-west.
(10) Turn right onto the path heading north-east to rejoin the D62a. Back on the D62a, turn left to reach Phalempin and the car park (S/E).
