Start from the church/town hall in Ons-en-Bray.
(S/E) With your back to the church and facing the town hall, turn left and walk up Rue de la Montagne, then take the first alley on the left.
(1) Turn right onto the path and continue straight ahead.
(2) At the crossroads, facing the plains, turn onto the path on the left. Follow the path straight ahead until you reach a road.
(3) Turn right and stay on the road. At the intersection (elevation 145), continue straight ahead. Pass through the woods while following the road.
(4) At the edge of the woods, take the path on the right (there is a tree on the left). You will come to a second path on the right (the one with a red and white barrier).
(5) Take it and cross the woods. Pass the barrier at the exit of the woods.
(6) Take the road on the left and continue straight ahead on the uphill path.
(7) At the top of the path, at the "No motocross" sign, turn right. Cross the woods and, at the exit, continue along the path. At the crossroads (elevation 125), cross the road and continue straight ahead. You will reach a crossroads.
(8) Turn right. Before the small bridge, turn onto the path on the left (caution: very wet area in case of rain). At the end of the path, take the trail on the left between the house and the building.
(9) When you reach the D109, turn right (Route de la Vallée). At the first intersection, continue straight ahead and at the second (stop sign), continue straight ahead. Pass the bar and the Ons-en-Bray bus stop. You will arrive at a large bend (bench).
(10) Turn right up Rue de la Côte Saint-Denis to return to the starting point (S/E).
