Route n°1 : An itinerary with plenty of shade, very pleasant in summer. Head for "La Pinéa" on the waymarked path.

Follow this path as far as the locality of Les Frettes. From there you can take the there-and-back singletrack variant which ends with a few rocks to "climb" up to the summit. You'll then descend to the riverbed and then go back up to Gervais before returning to the Col de Porte pass via Le Mauchon.
