Park in the centre of the hamlet of Mont Devant, just after the lodge.
(S/E) Head right (south-west), pass in front of a farm and continue to follow theGRP® straight ahead (red and yellow markings). This first climb leads to the road at a place called Sanguinaire. Continue right to Le Reposoir, where there is also a car park.
(1) Ignore the narrow path on the left that climbs directly to the Col de Bornette. Instead, take the wide, newly constructed track right next to it, which leads into the mountain pasture and joins theGRP® before the Noubloz chalets.
(2) After the chalets, follow the track for a while longer, turning right to reach the Col de Bornette.
(3) At the pass, turn left to rejoin the famous track, follow it again to reach the Mollard chalets, passing close to a cross.
(4) Pass the chalets via a zigzag climb to reach the Crêt du Char plateau. The plateau forms a sort of small pass between Crêt du Char (1,468 m) to the south and Roc de Four Magnin (1,645 m) to the north.
(5) There is no sign indicating Roc de Four Magnin: you must turn right towards the north (trail marks) to reach the base of the peak. Look for the yellow markings that mark the rocky trail, which is somewhat steep and sometimes exposed. By carefully following the yellow markings, heading generally north, you will first reach the secondary summit; continue along the ridge to reach the aluminium cross.
(6) Once at the summit, descend to Crêt du Char, continuing to follow the yellow markings carefully.
(5) From Crêt du Char, head south-west and then turn right to find the path that leads to Précheret. Before entering the woods, there is a signpost. Descend into the woods to reach the mountain pasture. The path ends at a fork below the Précheret chalets
(7) Turn left onto theGR®96, cross the Pontet bridge and follow the signs to Mont Derrière.
(8) Stay on theGR® trail, turning left. This is your chance to cross the pretty hamlet of Mont Derrière. Follow the road, keeping left at the first two intersections, then go straight ahead to return to the car park at Mont Devant (S/E).
