(S/E) Leave the car park and head towards the forest road leading to the car park. Just before the road, take the forest path on the left.
Continue along this path until you reach a junction with a road.
(1) Cross the road and continue straight ahead.
You can see a menhir on the left, amongst the trees. A second menhir is further on, amidst the greenery.
At the fork, turn right, heading west. Ignore a path on the left.
Follow the path as it bends to the left, then cross a road and continue straight ahead.
(2) Cross a wide path. This is the old narrow-gauge railway line (Ille-et-Vilaine railway) that linked Liffré to Antrain.
Continue straight ahead to reach the D92 road.
Follow it to the left for 50m, then take the road to the right and very quickly the path to the left.
Continue to the next crossroads.

(4) Turn left onto the road and follow it for 350m. Turn right onto the forest track and follow it to the end.
