Departure from the church in Auvers-sur-Oise.
(S/E) With your back to the apse of the church in Auvers-sur-Oise, turn left. After 30 metres, turn right onto Avenue du Cimetière (signposted "Tombe de Vincent et Théo"). Walk along the cemetery wall, then at its north-west corner, take the Sentier du Montier on the left (do not follow theGR® markings) and continue for 800 metres.
(1) Back in town, at the T-junction, turn right onto Rue Daubigny, following the red and whiteGR®1markings.
(2) 400 metres further on, leave Chemin des Vallées on your left and continue straight ahead on Chemin des Vallées au Veau.
(3) After 250 metres, in the middle of the hamlet in the clearing, take a small path on the left (yellowPR® + red and whiteGR® markings).
Walk for 2km in the Ravine des Vallées, heading north-north-west.
(4) At the T-junction, turn right onto the road.
(5) After 300m, at the crossroads, turn left onto the farm track (you will leave theGR® markings but stay on the yellowPR® markings). Continue on the main path for 1.8km, heading north-west then west, ignoring the paths branching off to the sides.
(6) At the T-junction, turn left (before the bird feeder). Just after a large warehouse (Bosh factory) on your left, turn right onto Rue de la Croix Rouge. At the next intersection, take Rue des Fichets on the left, which turns 90° to the right and becomes Rue Paul Ragnard. At the end of the street, turn left onto Rue Georges Duhamel.
(7) At the fork (Hérouville church opposite), turn right onto Place de l'Eglise. 50 metres further on, opposite the town hall, turn right onto Rue du Poteau. After 450 metres, continue straight ahead into the cul-de-sac.
(8) Cross Route de Beauvais (D927), the central reservation and then Route de Livilliers (D79). Then take the dirt track opposite, which runs alongside a shed on the left-hand side (security area). After about 1 km to the north-west, pass under a high-voltage power line.
(9) About 400 metres further on, take the path on the left (south-west) and join the D79 after 2 km.
(10) Turn right onto the road. After 350 metres, at the entrance to Livilliers, turn left onto Sentier du Bon Puits. The path turns 90° to the right 100 metres further on and runs along the edge of a field behind some houses. Back on the tarmac, continue along Avenue Saint-Fiacre to Livilliers Church.
(11) Go around the church on the left, then turn right onto Rue de Vaunay (you will see theGR®1trail markers again). The street turns left.
(12) Let the street turn 90° to the right and continue straight ahead on the dirt track (mountain bike sign). At the next fork, take the left branch (leaving thePR® and mountain bike markers). Continue south-west, between the fields or along the edge of the woods.
(13) Cross a small road and continue south through a wood to reach a roundabout.
(14) Cross through the pedestrian tunnel and continue straight ahead (follow theGR®1signs). TheGR® then winds through the forest on a cement road for about 700 metres.
(15) Leave this road and first turn left then right onto a small path that goes uphill (the cement road goes downhill). Go up the path, cross the Pontoise road and continue on Rue du Chêne.
(16) At the end of the street, take the old Beauvais road on the right. At the end of this road, take the dirt track that continues (south-east) and join a T-junction opposite a cross.
(17) Turn left onto the path. At the crossroads in front of the houses, go straight ahead (small left-right turn) and continue north-east for 600 metres to reach a road at a place called Le Reposoir.
(18) Turn right at an acute angle (south-east), cross the D927 road and continue straight ahead. Descend and reach a wooded valley. At the entrance to a hamlet, follow the Chemin de la Vallée de Cléry and continue south on the street that comes from the left.
(19) Turn left onto Sentier des Jardins (a small cement path that climbs quite steeply; do not continue along Rue de Valhermeil). After 50 metres, leave Sentier des Jardins and take a path on the left that climbs steeply (PR®-GR® markings, Sentier des Gobelins sign 700 metres further on). After the top of the hill, ignore three paths on the left.
(20) The path then turns 90° to the right: do not take the path opposite, but follow the double markings. At the road, turn left onto Chemins des Monts.
(21) In a right-hand bend, ignore the first path on the left and take the next one.
Be careful! You will come to two paths forming a "V". On a pile of rocks, you will see aGR® signpost pointing to the left. Do not follow this path, but take the one slightly to the right heading north-east (on the back of this rock, two markings clearly indicate the right-hand path) and continue to the crossroads just after a right-hand bend
(22). Take the path opposite. Ignore the path that immediately branches off to the right and continue south-east. At the end, turn left and then immediately follow the D928 road to the right until the next junction.
(23) Turn left onto Rue Léry. At the fork, bear left. At the three-way junction, turn right onto Rue Daubigny. Ignore all turnings on the right and continue to the church (S/E).
