The start sign is just below the church. Take the road up through the village, past the Croix Jacquaire, then join the RN122. Follow this road for a few dozen metres before crossing it to take the small road towards Col du Pertus and Mandailles.
Climb for a few dozen metres, then take the path on your right, then follow a grassy path that winds up to the La Bouguette viewpoint.
Turn right and follow the path, with Puy Griou in front of you. The path takes you to the Col du Gliziou, then continues uphill to join the GR400 at the foot of Puy Griou.
Walk around this superb rock cone.
You can climb Puy Griou, but beware: it's vertiginous and quite technical!
Descend to the Vacherie du Griou, through the scree, to return to Les Chazes.
From the Hameau des Chazes, you reach Les Boissines, then continue to cross the RN122. Then take the narrow road back to St Jacques des Blats and your starting point.
