Reach the village of Saint-André-en-Royans and park in the large car park next to the school.
(S/E) Head east on the road to quickly reach a trail.
(1) Turn right and follow the path alongside a walnut grove. You will come to a wide track.
Continue following the typical yellow and green Vercors trail markers. Cross the Route du Col de Toutes Aures and take it on the left.
At the next crossroads, leave the road and start climbing up the wide forest track.
(2) You will reach a new crossroads where a steep path starts on the left in the woods. Follow it, ignoring all the tracks or paths leading off to the right or left, and follow the yellow-green markings to reach the beautifully restored farmhouse.
(3) Continue east to the Ritanpan crossroads.
(4) Turn 180° left onto the path to reach the summit of Serre Cocu (sign).
(5) Return to the Rintanpan crossroads.
(4) Head north. Continue along this wide lane until you reach the Croix Bernard crossroads.
(6) Begin the descent into the woods, still heading north, which ends at the crossroads with the road leading to the hamlet of Les Guinardières. Turn right onto this road and continue for about 400 metres.
(7) At the next crossroads, leave the road and take the wide track on the left, continuing until you reach Guadeloupe. Turn left onto the track, then take the small tarmac road until you reach the crossroads.
(8) Make another 180° turn to the left to take the path and begin a fairly steep descent. Cross the Ruisseau de Chaussère, then climb briefly to reach the plateau before Monteux. Leave the Girardière path on your right.
(9) Continue west, then south and cross the hamlet of Monteux.
(10) At the exit of the hamlet, leave the paved road and take the wide track on the left heading south-west.
(11) Cross Les Courtioux, heading south to return to the original crossroads.
(1) Follow the same route as on the way there to easily reach the car park on the right (S/E).
