Park at the Carrefour du Poulailler, on the D108 between Fougères and Parigné.
From (1) to (3), this walk follows a section of the Route de la Pierre Courcoulé, developed by the ONF, where you take paths that do not appear on the IGN base map.
Unmarked
(S/E) From the Carrefour du Poulailler, head south-west along the Route Forestière des Courbes (signposted), a small tarmac road that starts after a forest gate. Pass an old stone cross on the left, climb slightly and then descend again until you reach a bend in the road on the left.
Yellow markings
(1) At the bend and before a path branches off to the right, turn left onto a path through the undergrowth (signpost). Descend a little and, at the fork that follows shortly afterwards (forest plot no. 37), ignore the path leading down to the right and continue straight ahead, climbing. Take a left-hand bend, cross a perpendicular path and continue straight ahead. Stay roughly level in a copse of young beech trees.
Yellow markings + yellow ‘4’ mountain bike markings
At a T-junction, turn right, head down a well-marked path and come out onto a road.
(2) Cross the road and continue straight ahead down a path. At the T-junction immediately after, turn left onto a good track with a stream on your right. Pass a house by a pond on the right. Continue eastwards then veer left. Very soon after, at a fork (not shown on the map), take the left-hand path.
Red and white + yellow markings
At a junction, the mountain bike signpost suggests turning right: continue straight ahead (north-north-west) and follow theGR®34to the Pierre Courcoulé dolmen.
Red and white markings
(3) After the dolmen, turn immediately left into a forest track, ignore the trail junctions to the left or right and return to the starting point (S/E).
