Start from Rue de la Chaume in the village of Perreuse (municipality of Treigny-Perreuse-Sainte-Colombe).
(S/E) Head due north along the street that runs alongside the fields. Then, at the junction with the road, take the path opposite that leads down to the Marlée wash house.
(1) Continue west-north-west. At the first path, after about 1 km, turn right to climb towards the hamlet of Les Gourleaux.
(2) Before the hamlet, at the top of the hill, take the small path on the right which leads to Les Devaux. When you reach the tarmac road, turn right onto the main road. Continue along this small road, passing the few houses on your right.
(3) Before the sharp bend in the road, take the path on the left. This leads to a right-angled bend in the road.
(4) Take this road on the left and head downhill to reach the first house on the right (a farm).
(5) Take the stone path opposite and walk on until you reach the Croix Saint-Nicolas at the next crossroads.
(6) Turn right; the path leads to a road junction.
(7) Head down the tarmac road to the right, towards “Perreuse-Source du Loing”.
(8) After stopping at this spring, the route of which is marked on a stone monument, continue along this tarmac road.
(9) Turn slightly left, staying on the road.
(10) Head left to reach the orientation table.
(11) After taking in the view from the table, head down to the left and take the path on the left for just a few metres. Turn right onto the path running parallel to the road. Continue to the entrance to the village of Perreuse. Turn left into Rue des Crôts to reach Le Sully (a remarkable lime tree).
(12) Head downhill to the left and return to the starting point by turning right onto Rue de la Chaume (S/E).
