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.
The calculation of the difﬁculty of each course takes into account the length, the positive vertical drop, the greatest continuous positive or negative vertical drop as well as the technicality of the terrain.
All year round.
The starting point is : from the Prairie du Col de Porte
