Rocher du Trenze and Bayardet, Trail #20

Description

A rather athletic trail that won’t disappoint. Steep paths, the Rocher de Trenze, the Jasse d'Olibou and more: a summary of marvels ! You start with a downhill section of about 4km on narrow and sometimes rocky paths, some peatbogs too, but nothing too technical. You will go through several cattle barriers, remember to close them properly. A short but steep section leads you to splendid panoramic views over the Cévennes and announces a grand descent along Le Trenze cliffs. At the Rocher du Trenze, the descent becomes steeper and more technical, until you reach the Col de Montclar pass. Then a short portion on a track before you take a cheerful singletrack that is rather steep. At Les Bouzèdes, the hardest part of the ascent is over. Just one more uphill kilometre on a path before reaching the track. The circuit ends with 2 km of level ground on a pretty forest track. A short version, waymarked 20v, lets you shorten the circuit to 10 km. Follow the waymarks for trail #20. Signposts will guide you all along this route, as well as yellow painted waymarks.
