Depart from the Col de Grimone (altitude 1,319 m) on the D539, which connects Lus-la-Croix-Haute to Glandage. Park in the car park at the pass.
(S/E) Crossroads of tracks and paths. Take the path on the left, heading south towards Combefère or Col de Lus. The path, which starts in the woods, offers views of the highest peaks of the Drôme in places. Walk along the almost flat path to reach the Combéfère fork.
(1) Take the path on the right, which climbs towards the Col des Prêtres. Go around Serre les Têtes before reaching the Col des Prêtres.
See practical information for a possible alternative route.
(2) At the fork, turn right towards Serre les Têtes. Very beautiful scenery. You will reach a crossroads at the point marked Serre les Têtes.
(3) At the fork, turn right towards Col de Grimone. The path is rockier, descends and has a few hairpin bends.
