Park in the large car park on Place de Haïphong, located between the town hall and the church in Chavignon.
Yellow and purple markings (see practical information)
(S/E) Turn your back on the church and head towards the town hall. At the foot of the building, turn right onto Rue Lucien Lemoine. Continue straight ahead, cross Rue de l'Angle Vert on the left-hand side and continue along a track. Cross a stream and you will immediately come to a crossroads.
(1) Then turn left. Pass under a power line and turn left onto the main path. Walk along a stream on your left, then head towards the village of Bruyères. Return to the tarmac road and, at the T-junction (with the EDF power station opposite), turn right onto Rue des Grès.
(2) Then turn left onto Rue du Clerc. The tarmac quickly gives way to a path between fenced meadows. Walk gently down this grassy path. At the crossroads (elevation 67), go straight ahead.
(3) At the T-junction, follow the path lined with poplar trees to the right. Continue straight ahead, then turn right onto the path to cross the Bois Lombard. Ignore a path on the right, then one on the left, exit the woods and follow the winding path. Ignore a path on the left, pass under a power line and you will immediately reach an intersection.
(4) Continue straight ahead and cross Cité Gilbert, ignoring all the turnings on either side. Leave Rue de la Bondelette on your right. At the "Give Way" sign, cross the D23 and follow Rue de la Croix. At the crossroads, turn right and then cross Rue de Pargny on your left.
(5) At the next intersection, turn left onto Rue du4e Zouaves et Tirailleurs. Cross Impasse du Chemin des Dames on the left-hand side and continue straight ahead on the tarmac road, which soon gives way to a dirt track. Stay on the main track, keeping to the right-hand side of a field bordered on the right by a poplar grove.
(6) At the intersection at the end of the poplar grove, turn left and walk along the Bois de la Garenne on your left. Walk up the Vallée de la Malmaison. When you reach a small masonry structure on your right, listen carefully to hear the regular hammering of the hydraulic ram (information sign).
(7) Continue up the path. Return to the tarmac road and climb steeply. At the crossroads, take a stony track on the right. At the "Give Way" sign, cross the D23 (be careful, there is no protected crossing) and follow the track opposite.
(8) At the fork about 50 metres further on, follow the less obvious path on the left (gravel, marker post). Enter the woods and descend gently. Further on, leave the woods and ignore a path on the left.
(9) Ignore a path on the right (view of the town of Laon and its cathedral), turn left and descend into the woods. Ignore a path on the right (the purple line supposed to represent thePR®® is inaccurate here), cross a stream and leave a metal barrier on the left. Pass a wash house on your left, continue on the tarmac road and walk alongside the houses on your right.
(10) Come out onto the D192 (remains of the old church of Vaudesson on the left) and follow it to the left. Go up and stay either on the left-hand side of the road or behind the safety barrier on the right-hand side (a few sections on a slope).
(11) At the top, shortly after the end of the safety barrier and at the corner of a fence, turn right onto a path towards a small shed. Pass it and, shortly after, at a fork not shown on the map, turn right onto a grassy path leading downhill. Alternate between shaded sections and sections along the edge of the field. You will come out onto the D192 (cemetery opposite) and follow it to the right at an acute angle.
(12) Take thefirst left at an acute angle (large crucifix). The tarmac quickly gives way to a farm track. At the four-way junction (elevation 103), bear slightly right (east; do not take thefirst path on the right heading south). Ignore a path on the right, go around a small poplar grove on the right and follow the grassy path that winds between the fields.
(13) At the T-junction, go left where there are two parallel paths (the map shows only one): take the one on the right. Follow this shaded path, pass an isolated house on the left and join the D19. Cross the road and follow it to the right for about 300 m.
(14) Take thefirst path on the left towards a fenced-in meadow and a young poplar grove. At the entrance to the meadow, turn right. Walk along the young poplar grove and then a fenced-in pond on your left. Continue along the path lined with very young poplar shoots.
(15) At the end, turn right and then left at the stop sign. Continue straight ahead, walk past a school and return to the car park where you started (S/E).
