Park in the Roc la Tour car park.
Access is via the Route de la Lyre at the Monthermé exit, heading towards Belgium.
(S/E) Take theGR® towards Roc la Tour (south). Leave the rock piles on your right and stay on theGR®. After a rocky descent, ignore the path on the right that leads back to the starting point.
Continue for about 50 metres, then leave theGR® by turning right onto a small path.
The path turns left and descends towards a wide forest track. Take it to the right until you reach Route de la Lyre.
(1) Go up to the right on the path and rejoin theGR® at a place called Auton.
Turn left towards Les Cerceaux and follow the marked path to Ruisseau de la Lyre.
(2) Leave theGR® again by fording the stream and climb up to the right. Walk along the stream until you reach a wide path.
Turn right, cross the Lyre on a footbridge and join the Route Forestière des Woieries.
(3) Take it to the right and turn left as soon as possible. Walk along a recent conifer plantation (on the right) for 150 metres, then take the first path on the left to reach the edge of the national forest on the edge of the Woieries pastureland. Follow this edge to the right until you reach a forest path.
(4) Continue straight ahead (yellow marked trail). Climb gently for about 30 metres and turn right to reach Tchar Scaille and the Six Chênons clearing.
Descend to the old hamlet and turn right. At the next fork, turn left for a short distance onto the Six Chênons forest road and look for a path on the left that joins the edge of the national forest.
(5) Follow it, then turn right along the edge of the forest plots and turn right again.
Then leave the path that branches off to the right and, after a descent, join a large forest path marked in yellow.
(6) Continue in the same direction. Several hundred metres further on, leave the marked path at the point where the sign points to the left. Continue straight ahead on a little-used path, keeping roughly the same direction until you reach a cross path.
(7) Descend to the right and join a path marked in yellow. Turn right onto the marked path. After passing through a wetland area, keep left and continue to a place called La Gire at the crossroads with the Route Forestière de la Dauphiné.
(8) Continue straight ahead on the marked path until you reach the junction with the Route Forestière des Éteignères. Stay on the path until you reach Chemin Lagard (signposted). Here you will rejoin theGR® trail. Take it to the left to quickly reach the Roc de la Tour car park (S/E).
