Departure from the car park at the town hall and the village hall in Thierville.
Unmarked route
(S/E) With your back to the village hall, take the path opposite which crosses the plain. At the end of the path, follow the small road to the right, Route du Manoir Cornet.
(1) At the end of Route du Manoir Cornet, turn left twice to join Route du Bec. At the first path, turn right. Once back on the tarmac, ignore the path across the plain on the left and continue straight ahead.
(2) At the crossroads in front of the bus shelter, turn left onto Route des Champs. At the hamlet of half-timbered houses, turn left first and, 50 metres further on, turn right onto Rue de la Fontaine, which continues as a path.
(3) As you enter the forest, turn left towards the concrete bollard. At the junction with theGR®, head down the path opposite into the valley, following the signposts for the Chemin de Saint-Michel all the way to the bottom.
(4) Just before the bridge over the old railway line, climb up the embankment to the left. Take the old railway line to the right to cross the bridge and enjoy a superb view of the Risle valley (watch your ankles, the ballast is still in place). After 500 m along the track, turn right into the next valley and head straight up into the forest.
(5) At the top, at the corner of plot 84, enter the Montfort State Forest on the left by going through the gate. Follow theGR® 224 straight on, cross two roads and descend into the small valley. As the descent is very steep at the start, a small path on the left allows you to bypass the scree and descend on a gentler slope, giving your ankles a rest.
(6) At the bottom of the small valley, after crossing the dry riverbed, leave theGR® andcontinue to the right to go deeper into this small valley. After 500 m, head up to the right.
(7) At the Quatre Frères crossroads, admire this remarkable tree and head off to the left to climb gently straight up to the top.
(8) At the top, at the crossroads sheltered by a large beech tree, take the small path opposite to the right of the caravan. As you leave the woods, go through two pedestrian gates in the cattle fences and continue along the pretty path between two hedges which takes you back to the village. N.B. If you come across cows, cross calmly without making any sudden movements or speaking loudly; dogs must be kept on a lead at all times. At the end of Allée des Marronniers, turn right onto Rue Eleonora de Cheddeville, then left at the church to return to the start (S/E)
