Walk carefully along the edge of the road, and 100m to the left, turn onto a tarmac lane. At a bend in the road, take the small damp path to the left of a calvary. Pass under the canopy of trees and find a grassy track further down. Turn right and join the Chemin de la Tour ahead. At the large roundabout, turn left (D607) and go straight ahead as far as the car park.
