(3) Take the second track starting on the right after the cemetery. This marks the start of a long stretch through the grasslands with views stretching into the distance, particularly over the Montmorency Forest and the Isle-Adam Forest, as well as the hills towards Parmain. Take the first track on the left, which climbs slightly. Ignore the first track on the right, then the next one coming from the left.
