You arrive in front of an old quarry where you can see some sandstone extraction marks used for the mills.
Cross the stream “La Baye” and turn right on the steep path. This path goes along the stream in beautiful surroundings.
You will pass a first mill in ruins. Continue straight on to go to the mill of Prat-Ferrand. Turn right on the hairpin bend to go up to the village of Villevayre.
At the last bend you can have a look at a small cave if you turn right and continue for 100 meters. Otherwise continue to go up to Villevayre.
