From Briançon, take the RN94 towards Gap. Once you reach Prelles, turn right onto the D4 towards Les Vigneaux. A few kilometres further on, at the letterboxes, take the track on the right towards Bouchier.
Drive past the hamlet and continue along the track to the right towards La Blétonnée (GR®®50). The track climbs through the forest and leads onto a plateau. On the right, you’ll see a row of white boulders. At this point, another track joins and climbs to the left. Park on your left near this junction.
(S/E) Follow the track to the left of the path heading south. This climbs steeply through a larch forest. On this ascent, you will come across three track junctions.
(1) Take the one on the left.
(2) Continue along the main track to the right.
(3) Take the one on the left. The track then turns into a path. Follow this path to reach and then follow the northern ridge.

Then climb up the ridge on the right and make your way to the cairn and the summit cross.
