You can park at a place called Bois de la Chapelle.
(S/E) Once parked, with your back to the path you have just taken, head towards the path on your right that runs alongside the woods and continue straight ahead.
At the end of this path, turn right (you will have no choice anyway), continue straight ahead, take the first left and continue on your way.
(1) Further on, take the first right and continue straight ahead on the path that descends steeply until you reach the departmental road (D42), which you will cross to continue on your way opposite.
From there, continue straight ahead (you will see a path on the right and then on the left, but do not take them).
At the end of this path, you will have no choice but to turn right, and you will be separated from the motorway by a field. Continue straight ahead until you come to another district road (D42a).
(2) Turn right onto the road (which has little traffic) and walk along the verge towards the village.
Once in the village, continue straight ahead. Look for the wooden bus shelter further ahead on your left, just before the left-hand climb that you will take to continue your walk.
Once on the steeply ascending path, continue straight ahead until you come to another country road. You will then see a dairy farm on your left and, to the right of the farm, a stone path.
(3) First turn right then left and take the path. Continue straight ahead and at the end of the path, you will see a military monument surrounded by tall pine trees. Turn left onto the same road you took with your vehicle. Continue straight ahead to reach the vehicle (S/E).
