The route starts in Chastenay, specifically at the foot of the church in the car park situated between the old school and the church.
(S/E) Walk down the street, passing the public weighbridge, to reach the main road. Turn left onto it and immediately turn right towards Ouanne. At the first junction, keep to the right, heading straight up until you come to a path. Take this path and head uphill, crossing straight through the hamlet of Chicorneau.
(1) Carry on straight ahead along this road for about 400 m until you come to two paths crossing it at right angles (elevation 320). Take the one on the right and carry on straight ahead until you reach the junction with the D85.
(2) Cross with care and take the path opposite for about a hundred metres. Continue, keeping to the left-hand side of the road for 150 m. Turn left, then go straight on, ignoring the path on the left. Head downhill towards the wooded area to rejoin the Duenne access road.
(3) Cross this track, head towards the houses and, at the three-way junction, take the left-hand road. This ends, after passing the wash house, in an uphill path. Continue on this path until you reach the junction of four country lanes.
(4) Turn right. Along the way, ignore the two farm tracks branching off to the left and take a track on the right.
(5) Take this path and pass by the base of the wind turbines on your left. Join the D125 road, turn right and arrive at a crossroads just before the hamlet of Vrilly.
(6) Turn left and begin the descent, with fields on either side. You’ll come out onto a road.
(7) Turn right and head downhill to the next junction (elevation 308). Leave the road and head right onto the gravel track, following it for about 300 m.
(8) Turn left, then, at the next junction, turn right. Walk alongside a hedge on your left. You’ll reach a junction with a cross-path.
(9) Turn right and continue straight on until you reach a partially tarmac-surfaced track. Turn left and join the D85 road.
(10) Cross this road with care and take the tarmac road opposite (towards Chastenay-le-Haut). Before reaching the houses in this hamlet, turn left onto the first track. At the three-way junction, take the track leading off to the right. After walking alongside a small copse on your right, at the end of it, you’ll find a track on the right.
(11) Walk down along the edge of the woodland until you reach a crossroads with four paths (the one opposite is often heavily overgrown).
(12) Turn right onto a narrow path lined with hedges. This descent is quite steep (the route is not marked on IGN maps). Just before the end of the descent, turn right onto a path that winds through an open garden. Stay on this path, which has steps and a handrail, to reach the wash house on the left (just after the path that climbs up to the left). Walk alongside it and head towards the church with the old weighing area (S/E).
