Start at Pont Tranchefétu on the D921 (start on the bridge).
(S/E) Leave the bridge heading towards Chartres (north-east) and immediately turn left into the dead-end street. Take the path at the end of the street and follow the banks of the Eure. Continue straight on when the path becomes tarmac again. At the crossroads, turn left towards the station on the D343.
(1) Before the level crossing, take the path on the left running alongside the railway line for 800m.
(2) At the old level crossing (closed), turn left. 200m further on (marker 146), take the path on the right, before the woods. After 700m (marker 151), take the path on the left for 600m, then turn right towards the village of Nogent-sur-Eure. The path becomes a road as you enter the village.
At the T-junction, turn right, passing the town hall and then the church.
(3) Turn left onto the D123. Cross the D921 and pass through the hamlet of La Martinière. At the end of the road, turn onto the path on the left before the stream. After 700m, cross the D123.2 and continue straight on. You will rejoin theGR®655O, which you will follow for 300m.
(4) Continue straight on and leave theGR® which turns left. Carry on for about 1 km along the path beside the stream. The path then turns left. Follow it to the track at the edge of the woods.
(5) Turn right onto the path running alongside a woodland. After 400m, you’ll enter the undergrowth. Ignore the first path on the left and take the second one as you emerge from the undergrowth. After 400m, you’ll cross a path; continue straight ahead. This path is a little narrower. Cross the road and continue along the street opposite. After 100m, the street turns into a path and you continue through the woodland for 1.2km.
(6) Turn left onto theGR®655O. You can either continue on theGR® or take the parallel path running alongside the Eure below: this second option, not shown on the IGN map, is the one recommended and indicated on the route.
(7) In both cases, after 650m, take the small bridge crossing the Eure on the right (be careful not to miss it if you have stayed on theGR®; it is below). Follow the narrow path along the Eure through the tall grass to a footbridge on your left, which you should take, then turn right along the pond. You will reach the D149; turn left onto the cycle path running parallel to the road. Turn right onto the first track and follow it for about 700m.
(8) When you reach a stream on your right, turn right onto the path that crosses it. The stream passes through several concrete culverts beneath the path. Follow the path through the woodland for 300m. At the T-junction, turn left to rejoin the track between the ponds. Follow this track for 500m. When it turns left at a 90° angle (with a pond opposite), turn right after the fence and follow the track to the right past the two successive ponds. At the end of the second pond, you’ll join a track suitable for vehicles; take this by turning right. You’ll then rejoin the D921 at your starting point (S/E).
