MTB route no.25 Le Bonnan

From the Coustou parking lot, take the path leading to the "Mère de Dieu" spring before crossing the Grézelles forest and emerging onto the Pech de Marnaves.
Descend towards Milhars via the trails. In the village, follow the path that runs alongside the Cérou to the La Garenne mill before ascending through the Bonnan Valley. Follow the Bonnan stream, and you will see the tufa waterfall on your right.
Next, ascend the path to the place called "Fourcou." Turn right towards the Pas de la Clède and climb back to Roussayrolles via a rocky path. Finally, return to the village, passing the small cross of Nougayrols and the Foun Naouto crossroads with its stone picnic table and weeping willow.
