A superb cycle route through the undergrowth with magnificent views of the Gap Valley. The Buzon viaduct at the start of the climb is currently under construction. It should reopen in late autumn 2025. The finish is at the Col de Manse, opposite the imposing "Vieux Chaillol" which rises up in front of you from its 3,163m altitude.

A pass with unrivalled views of the summit of l'Obiou, the highest mountain in the Devoluy Massif. Even if the summit is covered in clouds, it is worth visiting the place.
