The start is at the Col des Annes at 1,720 m. There is a small car park. If this is full, park along the road as you climb.
(S/E) At the pass, take the wide, carriageable track heading south-east towards the Refuge Gramusset. Stay on this wide track, ignoring the paths on either side, and you will reach the Tête des Annes (top station of a chairlift).
(1) Continue south-east. Pass directly below an unnamed peak with an altitude of 1,950 m and then the Pointe des Delevrets. You will reach the Col de l’Oulettaz.
(2) After the pass, the path turns south-east and begins to descend for a few dozen metres. The climb resumes quickly. Continue straight on (south-south-east).
(3) At a junction, turn left (east-southeast) and climb the switchbacks to the Refuge Gramusset, which can be seen from below.
(4) From here, there are no further signposts; you must visualise the route and follow the red dots or lines visible on the rock. Head east, to the left as you leave the refuge, and take care on the sharp limestone pavement. Then climb up a scree slope with numerous switchbacks of varying prominence. A snowfield may be present depending on the season.
(5) The climbing section begins here; it is not particularly difficult if you follow the red markings carefully. Head first towards the summit (east) then veer right (south-east).
(6) At this junction, turn left and follow the markings to the summit. Beyond this point, and as you approach the summit, the climbing becomes more exposed. Take care with your footing.
(7) For the descent, take exactly the same route; don’t hesitate to use your hands and knees to steady yourself. This will take you to the Col des Annes (S/E).
