The start of the hike is located just before the car park at the entrance to the old village of Teyssières.
(S/E) Coming from the car park, take the track on the right and follow the signs for Le Cougoir until you reach a crossroads 300 metres further on.
(1) Leave the path on the left (return) and continue on the track. After passing three hairpin bends, continue for another 150 metres and take the path on the left. Do not continue towards the house.
Continue along the path towards Col du Bouton, which will quickly turn into a well-marked trail. Follow a wire fence, then an electric fence, and join theGRP® Tour du Pays de Dieulefit trail at Adret de la Lionne (the IGN map is inaccurate at this point; the actual route is as described here). Follow the path that gradually climbs to the left towards the Col de la Pause until you reach it, then take the track on the left until you reach a meadow.
(2) Opposite, halfway up, join the metal gate in the fence which marks the continuation of the trail.
This crosses a short section of forest and arrives at a crossroads.
(3) Leave the path that climbs to the left towards Montagne de la Croix and continue right towards the south, towards Col de Venterol. Then descend towards the small valley on the left. Continue along the mountainside, pass a rock in a left-hand bend, then after the bench, follow the path downhill which turns into a small track until you reach a hairpin bend that turns right just before the Col de Venterol.
(4) Take the path that branches off to the left towards the east. This joins a track about a hundred metres further on. Follow this uphill to the first hairpin bend on the left, then continue opposite on the path that joins the rocky ridge at the Pas de la Pousterle.
(5) Continue climbing to the left, following the ridge to the summit of Cougoir.
(6) Head west towards the promontory of Montagne de la Croix, taking the path that passes through the small pass.
(7) Just before the summit, take the less marked path on the right towards the north. Follow the Crête des Rochers du Clos to the hollow, then turn left across the grassy slopes to reach the top of the valley at point 1069. Reach the Clos du Puits by following the summit and then continue along the ridge, which is almost horizontal.
(8) Take the descent via a faint path (marked by a few small cairns). This passes to the left of a rock head that protrudes slightly from the ridge line and then becomes more distinct. After passing under a small cliff, it turns right and joins the ridge of the Sauveginoux mountain in the undergrowth. Follow the trail to the track at Col de Fonturière.
(9) Take the track on the left, heading north. Follow it downhill, ignoring all the paths on the right, until you reach the Auberge de Mielandre. Then turn left until you reach the Ravin de Cougouare bridge on the D130 road.
(10) Take the dirt road that climbs opposite, heading west, and follow it to a three-way junction.
(11) Continue on the right along the path that joins a field at point 643. Take the path that goes around the field on the left. This joins the bottom of the valley, follows the stream and turns left across it. After several small ascents and descents, the path joins the track you took at the start.
(1) Follow this track to the right until you reach the car park (S/E).
