Parking at the Roche-Guyon Regional Forest on the RD100 (Route des Crêtes).
(S/E) Set off along the main path with your back to the car park entrance. Turn into the first path on the right and then take the first path on the left. Follow it to a crossroads.
(1) Continue straight ahead on a path that descends to the edge of the woods with a meadow on your right. At the bottom, turn right and you will soon reach a wide path. Follow it to the left until you reach a road.
(2) Take the first road on the right towards Le Chesnay. After 200 metres of climbing, turn sharply right onto an uphill path (yellow markings). Go through a gate to enter a meadow. Follow the main track, which turns left and climbs up the meadow to another gate.
(3) Once you have passed the barrier, turn right, initially following the fence, and continue along this path for about one kilometre. Leave the path that descends to the left and continue straight ahead on a wider path until you reach a barrier.
(4) Take the path on the left, which then turns right, leaving the path coming from the left, then turn left at the next junction. The path leaves the woods and climbs towards the village of Chérence. When you reach a road, turn right and enter Chérence.
(5) At the crossroads, bear slightly left, then immediately take the first right (Rue des Cabarets) and right again into Rue de la Corniche. At the end, cross the RD100 carefully and continue straight ahead on a carriage road. This road leads to a stone table with a view of the Seine.
(6) Take the small path opposite, which descends steeply towards the valley. Turn into the first path on the left, which quickly leads to the entrance of a cave that was used as a stone quarry in the 18th century for Parisian monuments. On leaving the cave, take a faint path that starts just to the left of the arrival path. At the end, turn left downhill. When you reach another path, turn left and then immediately right. Then take the first path on the right, which descends steeply to the edge of the woods.
(7) At the edge of the woods, turn left and walk back to reach a rocky promontory and enjoy the view. Retrace your steps.
(7) Continue down the winding path. The path eventually follows a fence on the right-hand side and arrives at a crossroads.
(8) Take the path opposite, which leads to the foot of a staircase carved into the rock, climbing up into a well-preserved bove (caution: do not climb if the rock is wet). Retrace your steps.
(8) Continue downhill to the left. At the bottom, join a carriage road, turn right and then go down a few steps to the left to reach the RD913. Cross it carefully and continue straight ahead on Chemin de l'Ormeteau.
(9) At the end, turn right onto Chemin de l'Abbaye; follow it straight ahead when it becomes a grassy path. Turn right at the end of the path and return to the RD913.
(10) Cross carefully and take the village path that goes uphill. Follow it to a crossroads. Take thesecond path on the left (red and whiteGR®2markings). Follow these markings for about 1.5 km until they indicate to turn right.
(11) Continue to follow theGR® for 100 m. The path then leaves the woods and arrives at a crossroads. Leave the red and white markings and climb to the right towards an orientation table overlooking the path. Continue climbing the path, which eventually crosses a meadow and joins the RD100. Follow it to the left for 200 m , taking care to return to the car park (S/E).
