After passing Engins and shortly before arriving at Lans-en-Vercors, turn right at L'Olette towards the hamlet of Les Aigauds, pass it and park above it, beyond the relay antenna.
(S/E) Take the wide path that leads to the Molière lodge. After a long, steady climb, you will come out into a more open space with a crossroads.
(1) Continue north towards La Molière, starting with a slightly steeper climb, and arrive at the Graille crossroads, where there is a signpost. Note the tracks on the right.
(2) Continue north and enter the mountain pasture. You will reach another crossroads.
(3) Follow the trail in a general northerly direction to reach the Molière Lodge.
(4) Pass the lodge and continue north along the impressive cliffs, reaching La Molière after passing a small building at a place called Sous Tracollet.
Take the opportunity here to enjoy the panoramic view with the help of the orientation table.
(5) Turn 180° south to follow the ridge. This route along the edge of the forest offers unobstructed views to the east. The trail climbs steadily to Charande, the highest point of the route.
(6) Continue along the ridge and begin the descent.
(7) Pass Pas de l'Ours to reach Pas de Bellecombe.
(8) Leave the trail that continues southwards and descend into the mountain pasture to rejoin the ascent route a little further down, at the crossroads of the mountain pasture.
(3) Follow the same route as on the way up to the Graille crossroads.
(2) Here you have two options:
- follow the same route as on the way up to return to the car park (S/E),
- turn left towards the east onto the green-yellow marked trail, typical of the Vercors, and descend into the forest to go around Montagne de la Graille. At the various intersections on the descent, stay on the green-yellow markings or follow the Visorando GPS track to find the road and then, shortly after, turn right at the Aigaux car park (S/E).
