Access via Voreppe, Route de Bourg Vieux. Outside the Stravinsky School’s opening hours, there is authorised parking in front of the school. Otherwise, park 100 metres before it, opposite the blocks of flats, or on Chemin des Rayettes in front of the houses.
(S/E) From the car park, with it on your left, head towards Chemin des Rayettes. A large boulder then appears through the vegetation and, just after that, a path cluttered with roots branches off to the left. This is the access path to the ramp, which determines the rest of the route.
(1) Climb onto the large boulder to see the position of the ramp on the right, which is overgrown with vegetation. Ignore the two paths on the left, continue along the steep path and reach the ramp.
(2) Once you reach the base of the large white cliff, the ramp is right there; a fixed rope has been installed in the most exposed section. You’ll then reach a bend and the ridge.
(3) The path turns left: this is the exit from the ramp. The slope is steep, and you never stray very far from the ridge. You will then join the Chemin du Belvédère de Bellevue.
(4) This is on the left. After your visit and some photos, take the Aiguille de Chalais path on the left. It is equipped with wooden railings and cables in places. Once you reach the foot of the Aiguille, turn left.
(5) After taking in the view and reading the information board, return to the previous junction and turn left towards the Couvent de Chalais. You’ll come to a Fork in the road with the Chemin du Belvédère de Bellevue.
(6) Turn left towards the Couvent de Chalais and go round it by taking the path opposite at the junction. Continue until you reach the path on the right.
(7) Take this path, which descends through the pastures. After a hairpin bend to the left, leave a path marked with blue signs on your left.
(8) Carry on to the right and you’ll reach a wide track which you should follow downhill. After a hairpin bend, you’ll come to a Fork in the road with a grassy track.
(9) At the junction of several tracks, take the one heading to the right; it is grassy and poorly maintained and offers a slight shortcut off the main track.
(10) Follow it to the right until you reach a path with blue markings on the right.
(11) Follow this path, which takes you on another shortcut. Be careful, as the slope is steep. Return to the track.
(12) Turn right and pass close to the old Sautaret cement works. Continue until you reach the Chemin des Rayettes path on the right.
(13) Turn right. Pass at the base of the southern ridge of the Aiguille de Chalais, which you climbed earlier. The slope is just beyond, higher up amongst the vegetation. You’ll reach the junction from the outward journey.
(1) Carry on straight ahead and return to the starting point via the reverse route of the outward journey (S/E).
