The circuit is signposted almost all the way and follows severalGR® trails (GR®7-GR®420,GR®73) as well as theGRP® "Tour du Mézenc-Gerbier".
It starts a few metres from the houses in the hamlet of Chantemerle, in front of a stone cross (parking available on site) on the edge of the D274 road.
(S/E) Follow theGR®7(red and white markings) past the houses of Chantemerle and climb the D274 road.
(1) Turn right onto the path that leads to a paragliding launch site. Follow theGR® trail, which turns left after the car park, to rejoin the road higher up. Continue up this road and, after a right-hand bend, take theGR® trail on the left, which brings you back to the road at Roche Pointue.
(2) Leave the road and follow theGR® trail perpendicular to it. Climb up and go around the Grosse Roche, keeping it on your left. You will come to a crossroads near the Grosse Roche.
(3) Continue straight ahead along a grassy path at the edge of the woods. Ignore theGR® which turns right along the track. The path joins theGRP® (red and yellow markings) in a sharp bend. Continue straight ahead for a few dozen metres until you reach the geodetic signal.
(4) Enjoy the unobstructed view of the Alps. Retrace your steps and follow theGRP® opposite, which takes a straight track through the forest. The track joins theGR® you left earlier and climbs with it to the Croix de Peccata.
(5) Take the wide signposted path on the left that leads to the summit of Mont Mézenc. The path climbs steeply and leaves the forest.
(6) It joins another path that comes from the right of the Croix de Boutières. Take this path, which descends below a scree slope before entering the forest again.
(7) After several hairpin bends, you will arrive at the Col de la Croix de Boutières, where you will rejoin the road and theGR®73. Descend to the left along the road with theGR® until you reach the hairpin bend.
(8) Opposite, still following theGR®, take the track that climbs slightly before levelling out. Enter the forest and descend a few hairpin bends. One of the last hairpin bends on the right leads to the access path to the ruined Gandoulet farm. Leave the forest, cross some old meadows and join the D410.
(9) Follow it for about 1 km. This will take you to the access road to the Médille stopover lodge at the pass of the same name.
(10). Do not go to the farm but take the path opposite, between the two roads, which crosses the meadows, reaches the edge of the woods and arrives at a small pass
(11). Here, don't miss the wind gauge by taking a path that climbs to the right (there are pedestrian crossings and signs for "le pays du vent"). The path continues along the ridge and reaches the famous wind gauge. Enjoy the exceptional view, then retrace your steps to return to the small pass.
(11) Descend to the right along the track with theGR®73but leave it at the first fork on the left for a good path through the woods. Climb gently then steeply before following the contour line and joining another small pass and theGR®73.
(12) From there, descend slightly to the left with theGR® and join a small road in front of the isolated house of Les Cris.
(13). Go back up this road on the left and return to Chantemerle and the starting point.
(S/E) The circuit ends with a tour around Mont Signon. To do this, follow the D274 road towards Chaudeyrolles. Turn left then right and enjoy the descent to admire the peatlands located in an almost perfectly circular ancient volcano.
(14) Before reaching the small road that climbs back up towards the church, take a path on the right that serves a few houses and joins the centre of the village at a large car park. You will rejoin theGR®7. Follow it to the left, then right twice to climb up into the village and reach a crossroads near a pylon and a statue of the Virgin Mary.
(15) Leave theGR® here, which branches off to the left, and take the path opposite that climbs towards Mont Signon, marked in yellow. From there, you will quickly reach the woods.
At the three-way junction, do not follow the right-hand branch that climbs up to Mont Signon, but continue on the wide path that curves around it. As you leave the woods, the path joins the yellow-marked trail coming from Mont Signon. Follow this trail downhill to a crossroads.
(16) Leave all markings and continue straight ahead on the flat. The path joins theGR®7and quickly descends to the Croix de Chantemerle (S/E).
A visit to the wind gauge is not to be missed!
