Departure
The hike starts at the car park below the ramparts, on the Compiègne road (D332), at the northern exit of Crépy-en-Valois.

No signposts
(S/E) Cross the Route de Compiègne (D332) and turn left onto the Route de Pierrefonds (D335). Shortly after crossing a stream at the bottom of the valley, when the road turns right, take the footpath on your left to climb up to the Chemin des Vignes.
(1). Turn left and continue to Rue d'Hazemont, where you turn right.
Continue to the next junction, where you turn left onto the farm track. This track soon turns right and heads north in a straight line for about two kilometres. At the end of this straight line, after crossing another track, turn right at the Y-junction.
(2) The road descends into a small valley and turns right, then immediately left.
(3) At the crossroads, at the end of the second bend, turn left onto Rue des Îles, then right onto Chemin du Lavoir, which crosses a stream and leads to Rue du Moulin.

(6) Cross the pretty River Automne. Continue straight ahead, cross the D123 and, after a left-hand bend, leave the D332 at the next bend (on the right) to continue on the marked path straight ahead.
The path runs alongside a copse and crosses a tarmac road.
(7) Continue straight ahead along the path that descends behind a property and arrives at Rue de Visery in the village of Orrouy.

After a left turn, you arrive at the junction with the D123 departmental road.

(10) Turn right and follow this road to the village of Glaignes, which you enter via Rue Chantepie.
(11) At the junction with Rue de la Sentelette, turn left onto the path behind the houses. Follow this path to the hamlet of Magneval, cross it and turn left onto the path that takes you back up to the plateau, where you will arrive at a track.
(12) Turn right and follow this track, which takes you across a large expanse of fields to the D332 departmental road (13).
