Park at the crossroads of the D292 road and a track between the hamlet of Les Bourguignons and the village of Boisinges (two or three spaces).
(S/E) Start on the track, heading north, then turn right towards Les Meulières à Vachat. Stay on the main track, ignoring the four paths coming from the right. After a slight descent, walk along the Marais de la Pierre du Mort; then the track climbs a little and descends slightly to a small clearing (La Pierre au Mort).
(1) Turn right onto a wide wooded path.
Note: see the Practical Information section for details on accessing Les Meulières.
(2) Turn right to reach the old Meulières quarry in Vachat, then turn around and continue climbing to a large plateau called Place des Danses.
(3) Turn right for a few metres, then left towards Crête de Chauffemerande. The path climbs up to the "Cri du Chardieu" sign. At this point, turn right onto a beautiful horizontal track.
Further on, ignore the wide path coming from the right and then from the left and immediately after the crossroads, join the Crête de Chauffemerande.
(4). Leave the track and take the small path on the right that leads into the woods towards Crêtes de Vouan. You will come to a crossroads with five paths.
(5) Please note: there are several trailheads that do not appear on the various maps; in addition, the orientation of the signpost is confusing. Continue straight ahead on the ridge. The trail quickly splits in two: take the one on the right, which is easier. Both lead to the ridge and continue to a wide track.
(6) Here you have two options: either stay on the track or continue along the ridge, following the sign for the path on a tree, and join this track a little further on.
Reach the Crête de Vouan. Stay on the track and ignore the path on the right, turning sharply left towards Trin Trin. You will reach a Y-shaped crossroads.
(7) Turn right along the ridge (option shown on the map) or continue along the track towards Trin-Trin, Sardagne and Sevraz. Join the tarmac road and follow it downhill, ignoring the two paths on the right until you reach the end of the bend.
(8) Leave the road by turning right at letterbox 447, cross the road further down and continue to the crossroads. Turn right onto the D190 for a few hundred metres, passing a wash house on the right, then a chapel on the left.
(9) At the three-way junction, turn right. Continue along this dead-end road, then along the path to rejoin the road and continue to the right.
(10) At the hairpin bend to the left, take the road opposite and immediately ignore the small road climbing up to the right. Return to the junction of the D292 and the track (S/E).
