Park at Place de l'Église in Saint-Julien-de-l'Herms.
(S/E) Leave the square by heading east on the D37d. The road immediately turns north. You will pass the town hall. Take the first small road on the right (signposted "chemin du Grand Bois").
(1) Pass a sawmill and continue straight ahead until you reach the edge of the woods. When you reach the edge of the woods, take the path marked "no vehicles" opposite. Follow this wide forest path, marked in yellow, until you reach a T-junction. Turn right and you will immediately arrive at the edge of the Ginot Pond.
(2) Pass this pond.
(3) A little further on, you will see a sign on your right: Étangs de Bonnevaux - alt. 500 m. Head straight ahead towards the Varèze valley, along a very large pond.
You will arrive at the D37 departmental road. Take the small road opposite, "Chemin de la Grande Bissera" (signposted). Very quickly, take a dirt track on the right (peg with black arrow on yellow background).
(4) You will arrive at the three beautiful ponds of Chaussées Courbes. At the end of the third pond, you will see a hut on your right and a T-junction. Turn left. A little further on, take the first road on the right (still marked in yellow). Leave a path that comes from the right just before you reach the D37 again at a stop sign.
(5) Cross the main road and take the Chemin de la Cage (signposted) opposite, slightly to the left. Very quickly, turn left onto a grassy dirt track. At a crossroads (concrete slab on the ground with a manhole cover), continue straight ahead to come out onto a small road.
(6) Turn left and then immediately right (several signs, including "Chemin des Lots"). Ignore a path on the right and you will come to a fork. Take the left path, Chemin des Calidonnes (signposted). Ignore a small road on the right before Maison Roux.
(7) After passing some buildings on your right, take the dirt track: you will see a yellow cross on a pylon opposite, otherwise the yellow markings are only visible further on. Walk through the forest, ignoring the paths that branch off to the right or left and keeping an eye out for the yellow markings. About halfway through the woods, you will see a discreet path on the right. Take this path (marked with yellow markings) and you will come to a crossroads as you leave the woods, with a sign saying "Vallée de la Varèze - alt. 410 m".
(8) Turn right towards Saint-Julien-de-l'Herms (2.3 km).
(9) At the hamlet of Chambaran, you will come to a small road which you cross. You descend onto a dirt track in a charming little valley, then, of course, you climb back up. When you reach a small road, take it on the right. When this road turns left, continue straight ahead on a dirt track.
(10) When you come to a T-junction, you will see the church of Saint-Julien opposite, through the curtain of trees. Turn right to come out onto the D37d with the cemetery gate opposite you and the water point on your left.
Go up to the left and you will very quickly return to your starting point (S/E).
