Starting point: Écouen Ézanville station.
(S/E) Take Rue de la Gare, then turn right onto Allée du Bois.
(1) Turn right onto Chemin des Bimes and continue in the same direction along Route du Lavoir d’Ézanville. Then take a path on the right as you leave the forest; this will lead you to Rue du Luat. Follow this street to the end, cross the railway line and you’ll soon reach a three-way junction.
(2) Go straight on along Chemin de la Baronne and keep right at the next junction to go round the Château du Luat and the secondary school of the same name.
(3) At the end of the street, turn left onto Route de la Tête Richard, cross over the four-lane road and reach the roundabout.
(4) Go round the roundabout on the left using the pedestrian crossing and continue straight on along Rue de la Belle Vue for 250 m.
(5) Turn left onto a small path which leads you to the hamlet of Les Prés à l’Eau, then onto Chemin de la Fontaine aux Loups. Follow this path to the left until you reach the crossroads.
(6) Turn right onto Rue de la Libération.
(7) At the junction, continue straight ahead along Rue de l’Église. At the sharp bend to the left, take the path straight ahead, pass in front of a chapel and enter the Montmorency Forest. Immediately afterwards, at the crossroads, turn left, cross the tarmac road a little further on and continue straight ahead (small pond on the left). Follow the edge of the forest and then head back into the woods.
(8) Cross the stream, turn left to follow it, then turn right onto the path called the Ruelle aux Loups. Cross a junction of paths and continue straight ahead. When you reach a road, go straight on; a little further on, at the Chemin de Saint-Prix, turn left between the fields until you reach the four-way junction.
(9) Turn left onto Chemin de Montmorency towards Luzarches, then right onto Chemin du Regard. Return to the tarmac road and continue to the junction. Turn left onto Rue de la Planchette, pass the Jardin de la Fontaine on your left and continue to the end. Turn right onto Rue de la Forêt.
(10) Turn left to follow this straight road. Continue along Rue des Poiriers, keep to the right at the cemetery and rejoin Rue de la Libération and the junction you passed on the way out.
(7) Turn right, heading in the opposite direction to the outward journey, until you reach another junction, which you also passed on the outward journey.
(6) Continue straight on along Rue du Petit Saint-Brice, then turn left onto Chemin du Bériot, which leads to Rue de Paris (D11). Follow this road in the same direction until you reach the roundabout you passed on the way there.
