Head to École en Bauges, then the Nant Fourchu car park.
(S/E) From the car park, follow the paved road closed to traffic for 800 m.
(1) Leave the road and, just after a small chalet, take a track on the right that crosses the Chéran via a bridge. Follow this track.
(2) Leave the path that branches off to the right towards Combe-Fort. The track quickly turns into a path that heads north-east. At an altitude of 1,430 m, you will come to the GRP® trail of the Massif des Bauges.
(3) Turn left. Near the Haut du Four chalets, the GRP® comes out onto a track. Follow it as it passes between the chalets.
(4) When you reach the Col du Haut du Four, at the fork, take the path heading due north towards the Col de Drison. At an altitude of 1,650 m, leave the path that branches off to the right towards the Parc du Mouton.
(5) At the Col de Drison, take the GRP® on the left and follow the ridge, which initially heads north-west before turning west. After a few hairpin bends, join the path, which is now closed, leading from the Coutarse ridge.
(6) Turn right to quickly reach the summit.
(7) The descent is via the western ridge. The well-marked trail zigzags down the face, then follows the ridge to a section covered with rhododendrons. After a few turns, the trail rejoins the one coming from Aulp de Seythenex.
(8) Take the trail on the left to quickly reach the Col d'Orgeval.
(9) Take the GRP® on the left down the slope. Pass to the right of the Orgeval chalets (formerly a refuge). Follow the track.
(10) At an altitude of 1,400 m, continue straight ahead, leaving the track that branches off to the left. From there, follow a sometimes steep descent to reach the tarmac road, then turn right to return to the car park. (S/E).
