Start
The hike starts at 32 Avenue du Maréchal Foch, in the commune of Chamant (Oise).
(S) Head north-west.
Walk along the Haras de Plaisance, whose facilities can be seen through a large hedge of deciduous trees, until you reach a fork in the road in front of the Chamant Pony Club. Turn left at the Pony Club and take the bridle path that curves to the left.
After about 600 metres, this track turns right at a 90° angle. Continue straight ahead on the forest path until the next crossroads, where you turn into the first path on the right. This will take you to the remarkable Chamant water tower.
(1) Shortly after the water tower, you will cross a forest road. Continue straight ahead for 500 metres, following forest plot 291.
At the junction with another forest road, cross over and continue for another 500 metres (plot 259 on your left) until you reach the next junction, which you also cross to arrive at a third junction 500 metres further on.
(2) Turn right and, after driving alongside plots 210 and 209 for 400 metres, you will come to a racehorse training track at the corner of plot 209.
(3) Cross this track and, a few metres further on, turn left into the undergrowth (it is well cleared) following the edge of a stream. After about 100 metres off the path, you will arrive at the Bertrand Fountain.
(4) Continue for about 50 metres through the undergrowth towards the north until you reach a path on your left, which you take to reach the end of the racehorse training track.
Turn right and follow the path uphill at the foot of the Chêne à l'Image (Oak Tree with an Image), located on a red and white marked trail.
GR® signposting (red and white)
(5) Continue past the Chêne à l'Image, then turn right onto theGR® trail, which turns right at a right angle 200 metres further on. After one kilometre, it crosses a paved forest road at Poteau des Blancs Sablons.
(6) Cross the crossroads and continue along the Route des Grands Chênes, which runs alongside plot 229. TheGR® turns left after 400 metres, then curves to the right until it reaches a forest track.
(7) Turn left onto the track to pass between plots 201 and 204, then between plots 181 and 182 after crossing a small road. Continue to the next road where you will find the Croix Saint-Rieul.
No signposts
(8) Leave theGR® trail, which veers to the right, and follow the paved road to the Carrefour de la Futaie with its signpost in the centre.
Cross the crossroads and follow the Route du Cerfouillet (2nd on the right) towards the Poteau des Dames. At the Poteau des Dames, turn left (north-east) onto the Route du Mont Pagnotte.
At the Poteau du Mont Pagnotte, turn left to go to the viewpoint. A wooden observatory has been built there.
(9) Return to the Poteau du Mont Pagnotte and turn right (south-east) onto the Route de la Fontaine Aubert, which runs alongside plot 94. At the next crossroads, turn right onto the path between plots 127 and 128. This path is a little overgrown in places. Starting in the south, the path then turns south-west and, after about a kilometre, you will come to a tarmac road.
GR® signposting (red and white)
(10) Cross the road and go straight ahead onto the path at the corner of forest plot 137. You are now back on aGR® marked path. Continue to the next paved road where you will find the Croix Saint-Rieul.
(8) Turn left onto the forest path between plots 180 and 182. You passed this way earlier in the opposite direction. Cross a small road.
No signposts
(7) When theGR® turns right, leave it and continue straight ahead until you reach the corner of forest plot 250.
(11) Turn left. At the next crossroads, turn right in front of the signpost indicating "Gallo-Roman temple 200 m".
After visiting the temple site, continue by turning right at the fork, following plots 251 and 281 in succession.
(12) Turn left at the corner of plot 278. About a hundred metres further on, you will see a row of stone blocks in the undergrowth on your right, the remains of an archaeological site. Turn right into the next lane running alongside plot 278.
Turn left at the end, then, about 50 metres further on, turn right onto a path that takes you closer to a large fence that you will see on your left when you reach the crossroads of several tracks and paths.
(13) Follow the path on the right that runs parallel to this wall. It will take you straight to the track running alongside the Haras de Plaisance. You will then reach Avenue du Maréchal Foch.
(E) The hike is now complete.
