Start from the car park on the right-hand side of the D101 (Route d’Orléans) on the outskirts of Semoy (towards Chanteau, Marigny-les-Usages)
(S/E) Take the wide, straight forest track (GR®® 3B) after passing the barrier blocking access to it.
(1) Turn right at the first junction onto the track known as Route de Semoy. Cross the old railway line.
(2) When you reach a tarmacised crossroads, turn left onto the track, leaving the Route de Semoy to continue to the right. Turn right when you come to a cross-track to follow the old railway line. Go through the gate, then follow the twists and turns of the main track. This runs alongside the main course of the Ruet stream until you reach the Étang de Ruet on your left, which you’ll follow until you come to a footbridge at the edge of the pond.
(3) Turn left onto the footbridge to cross the Ruet, then follow the pond on your left – an ideal spot for wildlife spotting. At the end of the path, cross the Ruet again to the right to reach a wide cross-path (with steps), along which you should head to the right. Ignore the side paths and continue along the straight Allée Pouet to the Château de Charbonnière. Go round the château to the left, following the small tarmac road.
(4) The narrow lane cuts across a cross-path. The tarmac quickly gives way to a forest track after the junction with a small cross-road (Rue de Charbonnière).
(5) At the next junction, leave the busiest lane, Rue de la Borde, and take a grassy path on the right. Cross Rue de Charbonnière. Access to the lane is restricted by two barriers on either side of the road.
(6) At the next junction, turn slightly right, leaving Rue de Compoint on your left and Rue de la Grenouillère on your right.
(7) At the next junction, take the left-hand path marked ‘Voie Verte’ and follow it all the way to the stud farm.
(8) At the crossroads on the edge of the stud farm, continue straight ahead along the busiest path, which you should follow until it meets a cross-path, after running alongside the old railway line.
(9) Turn right onto the cross-path and follow its winding course until you return to the starting point of the walk at the car park beside the D101 (Route d’Orléans) (S/E).
