(S/E) Continue along the Route d'Hauterives for 250 metres and take the Chemin de la Massonne, which descends to the left in the bend.
(1) At the crossroads, ignore the path that branches off to the left next to the house and take the path that branches off slightly to the right, ignoring the path and trail further to the right. Continue straight ahead and cross the Torrent de Combet several times.
(2) Leave it by taking the path that climbs to the right. Be careful not to take the first one, as it is a stream bed. Leave the first path on the left. After about 250 m, turn left at the first crossroads. Continue climbing to the plateau. Continue to the T-junction.

(5) At the crossroads, almost in the bed of the Ruisseau de Riançon stream, turn left and go up to the next crossroads. Turn left and continue straight ahead.
(6) Follow thefirst path on the right. Continue on the main path which descends towards the La Fabry neighbourhood.

(8) At the crossroads, turn left and immediately, after 20 metres, turn right. Continue and pass in front of the buildings. The climb is quite steep.
(9) Further up, leave the path that continues straight ahead and take thefirst path on the right. Continue straight ahead.
(10) Leave the path that climbs to the left, unless you want to see the Madonna (Notre-Dame-de-l'Assomption). Continue straight ahead.
