The start is located at the car park at the top of Route de la Creusière (Rue Maurice Pillet).
(S/E) Head east and follow the street for about 100 metres. At the entrance to a slight left-hand bend, take the first path on the left and descend into the woods.
(1) At the bottom, just before the edge of the woods, turn left onto the path with a gate. Cross the Bois de la Cencière, following the contour line, staying on the same path and ignoring the paths perpendicular to the various intersections. You will come to a T-junction.
(2) Then follow a paved path to the left for about 600 metres.
(3) At the end, turn left and then immediately right before a forest barrier. Go up and then down again until you reach a fork. Turn left and ignore the path on the left. Join another path and follow it to the left.
(4) You will come to theGRP® Ceinture Verte d'Île de France (red and yellow markings) and follow it to the left. Climb up into the woods. At the top, at a T-junction, turn right.
(5) At the barrier, turn left. Continue along theGRP®, heading west. At a T-junction, turn right. Then take thesecond path on the right, still following the GRP®.
(6) At the bottom of a short descent, turn left at an acute angle. Then take thesecond path on the left. At the T-junction that you will soon come to, turn right. Continue on theGRP® to the starting car park (S/E).
