(S/E) On leaving the car park, turn left, ignore the path on the left, walk past the Messy cemetery (on your left), ignore the path on the right and continue to the bend in the road where it turns left.
(1) Take the path on the right, then at the Fork in the road shortly afterwards, follow the path on the left. Further on, take the path on the right through the woodland, access the mound of earth on the right and join a path at the edge of the woods.
(2) This is the Chemin de Saint Mesmes. Turn right and you will arrive at Rue Royale in Saint-Mesmes. Turn left onto Rue du Four and walk past the Church of Saint-Maxime in Saint-Mesmes (on your right) at the junction with Grande Rue.

You’ll arrive at Place du Château de Nantouillet (a Renaissance castle dating from the 1520s).
(7) About a hundred metres further on, take Rue des Vignes diagonally to the right, ignore the path on the right and turn left, with the Ru du Rossignol on your right. Then follow Rue de la Rochelle, pass the Ferme de l’Abbaye and, after the left-hand bend, turn right along the D9 until you reach the former Collège de Juilly.

Carefully cross Rue des Prés Fleuris and take the path running alongside Rue de Meaux (D9) on your right. At the end of the path, you’ll see a cross on the right-hand side of the D9.
(10) Cross the main road carefully and take the wide path, with the Croix de la Sainte-Barbe on your right. Walk across the fields along the path leading to a Fork in the road and turn right, following the Ru de l’Abîme until you reach the next path on the left.
(11) Turn left onto the Chemin du Moulin, with the mill of the same name on your left. Cross La Beuveronne and turn left onto the next path. At the end, you’ll come back to the junction you passed on the way there, near the Nantouillet cemetery.
(6) Turn left, walk through a small wood and across the Champ du Puits, until you reach a crossroads.

After a bend to the left and then to the right, carry on straight ahead until you reach the junction with Rue de Charny.
