Magny-en-Vexin circular loop

Start from the car park of the supermarket located north of Magny-en-Vexin, on the edge of the D86, near the roundabout with the D983. Access via the D86 or, from the centre of Magny, via Rue de Rouen then Rue de Paris.

No signposting

(S/E) Head west, away from the supermarket, past the petrol station and leave the car park via the Rue de Paris exit. Follow the road to the left for about twenty metres.

Red and white markings (rare)

Turn right into Rue Alphonse Subtil. Then take the^first left, onto the gravel track known as Chemin de la Vallée du Prieur. Pass a chicane and continue along a grassy path. You’ll return to tarmac and immediately reach a crossroads.

(1) Then take the^first left, Rue du Maréchal de Lattre de Tassigny. When the street bends to the right, continue straight ahead. Pass a car park on the left and take the^first path on the right into a wooded area. At a junction, turn right and follow a grassy path to the bridge over the D14.

Red and white + yellow markings

(2) Go under the bridge and continue straight ahead. Ignore a path branching off to the left and continue straight ahead, first along a wall and then through meadows. After a short shaded stretch, you’ll reach a crossroads.

Yellow markings

(3) Turn right (let the^GR®11continue straight on). Climb gently between a field on the left and a fenced meadow on the right. Cross a short wooded strip and continue between the fields on roughly level ground. Come out onto a small road, follow it to the left and enter Archemont. Ignore a narrow lane on the left and continue through the village.

(4) Turn right with the road (there are two^{PR® paths} that split here; do not go straight on). Stay on the road, leave the village and climb gently. Descend again, following the D14 below on the right.

(5) At the “Give Way” sign, turn right and go under the D14 bridge. Continue straight on along the D983E (the purple line supposed to represent the^PR® on the 1:25,000 map is incorrect here). Two options for following this fairly busy road:
- cross the road immediately, where visibility is good, and follow it along the left-hand verge, which is narrow but protected for half the distance by a crash barrier;
- follow the road along its right-hand verge, which is slightly wider but unprotected, and, at a junction with a track, cross over where visibility is reduced.
In both cases, take great care.

(6) After a small black gate and at the corner of a wall (on the left-hand side), head down to the left onto a faint path running along the edge of the field on the right-hand side. Pass an old wash house and head back up. You’ll come out onto a road at the corner of the town hall and follow it to the left for a few dozen metres. Leave the signposting briefly and climb a staircase to the right (Rue de l’Escalier). At the top, turn left and walk past the church on your left.

(7) Pass under a chain and follow a narrow lane to the right, going uphill. Ignore a no-entry street on the left, rejoin the signposted route and, at the junction that appears immediately, follow Rue de Montagny to the left. Cross a road on the left and head straight on towards Montagny. At the fork that appears shortly afterwards (cross), turn right, still heading towards Montagny. Walk past the cemetery on your left and stay on the small road for about 1 km.

(8) Then turn right onto a poorly marked path and walk alongside a hedge of small trees on your left (no arrows or markers here). The grassy path joins a power line and runs parallel to it. Cross a road and continue straight ahead on the grassy path running parallel to the power line.

(9) At a junction at the foot of an electricity pylon, turn right (two^{PR® paths} split here; do not continue straight on). Head south along a grassy path running parallel to a different power line from the previous one. Ignore a turn-off to the right and continue south along a gravel track.

(10) At a fork where the slope levels out, take the path on the right, which is narrower and more shaded. Head downhill, noting a memorial stone on the left, and at another fork, keep to the right. Return to the tarmac and continue downhill. Take the^first left, Rue de la Croix, a roughly level path between two walls. At the end, turn right down Rue de la Cour Céleste. At the bottom, turn left.

(11) After about twenty metres, go down a flight of steps to the right and follow a winding path. After about a hundred metres, turn left and walk alongside a stream on your left. Walk alongside a field on your right and note a beautiful farmhouse on the left. Cross a small road and continue straight ahead along a grassy path, still following the stream. Cross the D86 at the pedestrian crossing and continue straight ahead along a path beside the stream. Pass by the foot of a statue of Christ.

No signposting

Ignore a footbridge on the left and cross a stream. Go through a small gate and follow a tarmac path towards the supermarket. You will then find the starting car park on the left (S/E).

Hiking boots recommended.

No water sources identified along the route.

This route is a shortened version of a hike designed and signposted by the Val-d'Oise FFRP committee. A detailed map is useful (at the very least the one accompanying this description).
