Start from the hamlet of Les Chazes (to reach this hamlet, go through St Jacques des Blats, then continue on the RN122 for about 2.5km. At the crossroads, turn left towards Les Chazes Hautes.
Once you've reached the signpost, take the small, level road that runs off to the left for about 300m. At the intersection after the last house, leave the road and take the path that climbs to the right. After a few hairpin bends, you'll come to a wide track.
Continue on this wide track for about 1km, ignoring the intersections. You'll come to a clearing.
Turn right onto a track that climbs up into the moorland and into the woods. The path climbs up through the beech forest to a small pass.
Climb into the forest, taking the path on the right. After almost 1km, the path leaves the wood to return to the summer pastures. Continue around Puy Griou.
You can climb Puy Griou, but beware: it's vertiginous and quite technical!
Follow the path back down into the scree: listen to the song of the stones beneath your feet!
When you reach the Vacherie du Griou, take time to admire the view! Then rejoin the track you took at the start, to reach the Hameau des Chazes.
