(S/E) Start from the Col de la Croix de Millet via the forest road that runs along the ridge in a south-westerly direction. Despite the cross at the end of the trail, take the north side of this ridge and not the other forest road that descends to the left.
(1) After 1 km, leave a wide path on your left. Continue along the forest road for 4 km. After a final hairpin bend, you will arrive at Col du Merle, where you will join the GR® de Pays "Tour du Tanargue" (yellow and red markings).
(2) Take the GRP® on the left. The path, which is wide at the start, continues as a very steep trail climbing up the rocks. Once at the summit, the trail runs along the edge of the woods and then arrives at a cairn marking the highest point.
(3) Turn 90° south. Walk along an electric fence bordering a pasture on the left. Follow the marked route to a point where the fence turns left at a right angle.
(4) Leave the GRP® and continue along the fence.
(5) You will come to a wide path, which is a road used to access the water catchments below. Take this road to the left, then left again at the next junction.
(6) Just before reaching the northern slope, in a right-hand bend before a left-hand hairpin bend, look for a small path on the left between the broom bushes that leads to the highest point of Cham du Cros.
(7) Retrace your steps. This round trip is optional, but it is from this summit that you have the most unobstructed view, particularly towards the Alps.
(6) Turn left and continue downhill along a well-marked forest road with hairpin bends. Pass through a barrier (open) prohibiting vehicle access. Return to the initial fork.
(1) Turn right to return to the Col de la Croix de Millet (S/E).
