Start at the Chérence cemetery car park.
(S) Head south-east, follow the ridge road (D100) eastwards (towards Vétheuil) for 200 metres. At the crossroads (cross), take the path on the right. Continue to the crossroads at the edge of the cliff (altitude 149 metres).
(1) You can go down the path opposite for a few metres and turn left to take a look at an old quarry dug into the rock, then return to the crossroads (option not shown on the map).
Otherwise, take the path that runs along the ridge to the west and ignore several paths branching off to the left.
(2) When the path joins the ridge road near a house, turn left onto the path that descends. At the T-junction, turn left and continue down Chemin du Village, passing the partly troglodyte houses of Haute-Isle. When you reach the D913, turn left.
(3) Continue on the D913 to reach the troglodyte church at the end of the cemetery a little further on. Retrace your steps.
(3) Turn left towards the Seine. Take the first path on the left, parallel to the D913 (on the left) and the Seine (on the right). Continue straight ahead on the paved road.
(4) At the wash house and the landing stage for Île de Moisson, go up the street on the left (Chemin de l'Ormeteau). Cross the D913 and continue opposite on Chemin de la Messe de Chantemesse, which starts with a few steps. Leave a chalky path on your right that leads to the foot of a limestone spur, then quickly turn left onto a narrower path that soon climbs in hairpin bends.
(5) A few hairpin bends higher up, a path climbing up a slope leads to a promontory offering a panoramic view of Vétheuil, the Moisson loop and La Roche-Guyon. Return to the original path and continue climbing.
Leave a path on your right and take the next one in a hairpin bend to the right. The path on the left splits into two a little further on. Finish the climb and join the ridge path at the end of the Chérence aerodrome runway.
(6) Continue straight ahead along the path that crosses the plain to join the paved road (D100).
(7) Turn left for about 100 metres, then turn right onto the first path. At the end, turn left onto Rue de l'Église, walk alongside the church and continue straight ahead onto Rue des Cabarets. Then turn left to go up Rue des Jardins and reach the cemetery car park.
