(S/E) Head towards the roundabout.

(2) In the housing estate, at the junction with the RD des Crozets, turn left, then right.
Walk a few metres along the D470E, then turn left and left again into Rue du Mont Robert.
Continue along this street, then keep right at the signpost marked “Sous le Mont Robert” towards the Rocher de la Vierge viewpoint.

After the cross, head onto the road that climbs slightly (Rue Claude Vincent). Continue along the forest path (GR®9) until you reach the D242. Please note: at the reservoir, the old route takes you to the right, but a local by-law prohibits access following a landslide.

(11) Turn left towards the south-east. Be careful, as it is easy to go wrong here, as the path is somewhat obscured by a tree growing out of the way. Continue along this path, following the yellow markings, to the Villards-d’Héria viaduct. Before the Villards-d’Héria viaduct, turn right to reach the car park (S/E).
Please note: Following a local by-law dated 8 March 2021, for safety reasons, access to the path leading uphill to the left at point (8) is prohibited.
