This rugged massif where thunder sometimes roars gave its name to this magnificent route, featuring some wonderful passes, such as the Croix de Millet, and especially the longest pass in Ardèche: the Meyrand with a 24 km climb.
It's a stunning, impressive circuit and a challenging one. There are a few formidable surprises for even the most experienced cyclists along its 220kms but it's worth the effort for the breath-taking landscapes, rare flowers, cultivated farming terraces and the usual warm welcome in the villages and restaurants.
