Park in the car park near the Fromelin ponds in the village of Langast.
(S/E) Take the path between the ponds, behind the children's playground. On the other side of the pond, you will come to a post marking the start of the trail. Head east between two fields. You will soon come to a trail junction.
(1) Take the path on the right that descends into the valley. Cross the stream. Turn right and cross the departmental road. Follow the stream.
(2) Continue straight ahead; a sign indicates La Roche au Cerf. The trail climbs, turning right when it reaches a field. Continue for about 50 metres, then take a path on the left (yellow markings). Follow this path, which turns into a farm track, to Ville-ès-Besnard.
(3) When you reach Ville-ès-Besnard, take the small road on the left, then turn right at the crossroads towards Le Coqueret. In the bend before Le Coqueret, take the path that goes straight ahead. Follow the signs for La Roche au Cerf. You will reach Moulin des Essarts on the banks of the Lié stream.
(4) Continue along the left bank of the Lié to reach La Teurse.
(5) Take the small road for 100 metres, then the first path on the right. This will take you to the Roche au Cerf site.
(6) Cross the river on the ancient stones of the ford or via the footbridge. The mill has been restored and can be used as a shelter. Cross the stream behind the houses, taking a path northwards, signposted Langast. You will soon reach the Cassebreil farm.
(7) Take the path on the right and follow it to Château des Essarts.
(8) Take the small road that crosses the farm, then continues along a beautiful tree-lined avenue. You will reach a T-junction.
(9) Stay on the small road by turning right, then immediately take the path on the left overlooking the valley before approaching the river. Follow this path parallel to the river without taking the farm tracks that branch off to the left away from the valley. Join the road after the hamlet of La Drolaie.
(10) Take this road on the right and continue straight ahead until you reach the Menhir du Saut Thébault in the middle of a field on the right.
(11) Stay on the road until you reach the entrance to the village of Langast. Turn right at the first street to return to the starting point (S/E).
