(S/E) With your back to Jaudrais church, turn right and head down the road that passes in front of the town hall. At the junction, turn right onto the D140.12, towards Maillebois. After the left-hand bend, continue straight ahead along the track until you reach the hamlet of Les Mares.
(1) Opposite No. 23, take the road on the left which crosses the hamlet. At the junction with the D30, continue straight ahead along the path which goes round the Bois Bouleau.
(2) At the road, turn left towards Jaudrais. At Bois Bouleau, just before No. 18, turn right onto the small road and, at the next junction, continue straight ahead along the path. Cross the Vau valley. View of the castle ruins. You’ll reach a road (D321.12) at the corner of the castle park wall.
(3) Continue along the path opposite, following the wall, then soon leave it behind and reach the Cour d’Aumoy. Carry on to the D321.
(4) Cross it carefully and head straight on towards La Mardelle. Ignore the road on the right and you’ll soon reach a four-way junction.
(5) Turn right (D30), follow the road carefully along the right-hand verge, pass under the high-voltage power line and head down towards the Houillé valley.
(6) Pass through the hollow of the valley and walk up it for a few metres. Cross carefully to take the path on the left, which first follows the valley and then climbs up to the right to join a road. Follow it to the left (D321.3) towards the farm in the hamlet of La Barre.
(7) At the three-way junction with a grassy island in the middle, continue left along the descending road until you reach the path branching off to the left 50 metres before the bridge over the Grande Vallée.
Yellow and red markings
(8) 50 m before the bridge, turn left onto the path that crosses the Grande Vallée and enters the Châteauneuf-en-Thymerais State Forest. At the forest entrance, follow the edge of the forest to the left. Further on, leave the GRP® trail, which climbs steeply to the right at the end of the Route Royale.

Take the track opposite, which runs alongside a plot planted with tall fir trees, and join the Route Forestière du Houillé. Turn right, pass a wooden building and reach the entrance to a track on the left which skirts the Bois des Mores.
(9) Follow this track until you reach the Route Forestière de Jaudrais.
(10) Follow it to the left for about fifty metres. You’ll reach the entrance to a track branching off diagonally to the right (plot sign 38). Take this track, cross a forest road that runs through the Bois de Jaudrais and continue straight ahead to the next track. Turn left along a new plot of conifers and reach its corner.
(11) Turn right, skirting the plot, and continue straight on along the path which leads to the edge of the woodland, behind the houses at Les Piperaux and then La Hennerie. The path becomes a track running alongside the road serving the hamlet, then winds its way above the D140. Join the Allée Centrale, which, on the right, leads to the D140 at the entrance to Jaudrais.
(12) Turn left onto the D140. Danger! Due to new roadworks near the bridge over the Grande Vallée, cross the road carefully first. Follow the right-hand verge. Cross the bridge using the zebra crossings. At the junction, continue alongside the cemetery to reach the car park in front of Jaudrais church (S/E).
