Departure from Acon Church. Small shaded car park on the north side of the church (immediately on the right when coming from the N12). Two hiking trails are marked at this point: here, we will follow the "Vallée et Bois" trail, in a variant that runs longer along the Avre River.
Red and white + white markings
(S/E) From the church, head south-west along the lane between the car park and the cemetery (formerly the Route du Mans). The tarmac quickly gives way to a path bordered by woods on the right and meadows on the left. Ignore a path branching off to the right and continue west through the undergrowth. Then continue south-west across open ground.
Red and white markings
(1) At the entrance to Breux-sur-Avre, turn left at the first street (ignore the white markings and continue straight ahead). After a few metres, at a "Give Way" sign, turn left again into Rue de l'Avre and cross the village. At the stop sign, continue straight ahead towards Le Voisinet, still on Rue de l'Avre. Cross the river and you will come to a crossroads.
(2) Leave the road and turn right onto the path that climbs steeply into the woods along the fence of a private property on your right. At the top of the hill, at a T-junction (not shown on the map), turn right, still following the fence. Ignore a turn-off on the left (not shown on the map) and continue on fairly level ground through the woods. After about 500m, descend and join the right bank of the Avre.
(3) Walk through the woods along the Avre on your right, ignoring any turnings on the left. When the Avre river veers off, walk along the fence of a private property on your right (note the remains of what was probably a chapel).
Red and white + white markings
(4) At the crossroads (footbridge on the right), go straight ahead and go around a large brick building on the left (the former Moulin de la Mulotière). Continue west on a small tarmac road.
White markings
(5) At a fork (large cross and memorial plaque), leave theGR®22continuing on the tarmac and turn sharply left. Pass a forest barrier on your right, then a path starting on the left, and climb up a wide path through the undergrowth. Turn left with the path, pass between two fences and continue east. After two left-right turns (less pronounced than on the map), walk east-southeast on a good path through a wood of oak and birch trees, ignoring the perpendicular paths that are much less marked.
(6) At the crossroads, take the first path on the left (orange cross) onto a sandier path, through some fir trees and fern undergrowth. Walk north-northeast for about 900 metres.
(7) Then turn right and soon leave the woods. Walk past a house on your left that is not shown on the map. Ignore a path on the left, walk along a fence on your left and enter a wood with birch trees and ferns. At a crossroads with a fence on either side, continue straight ahead and leave the woods. Walk eastwards, first between two fields, then along the edge of the woods on your left and finally along the edge of the woods on your right. Walk along a hedge on your left and head towards some houses. At the first house, ignore the path that goes down to the left and come out onto a small road.
(8) Follow the road to the left. At the next fork, take the left fork onto Rue du Grand Noyer. Cross the C33 road (which leads to Acon) and take Chemin des Bois opposite. At the fork a few metres further on, turn right with a meadow on your right. Pass a property and descend into the woods on a path not shown on the map. Make a sharp left turn to rejoin a road and follow it to the right. You will arrive at Pont des Planches.
White + yellow markings
(9) Cross the main branch of the Avre (wash house on the left) and then a secondary branch. Continue along the small road with the church of Acon in plain sight and return to the starting point (S/E).
