For trail runners looking for elevation gain and steepness, this circuit is for you. Although relatively short in distance, this loop has all the makings of a real mountain trail.
The ascent of the combe de l'Indrion and its steep slopes will challenge you, and you'll be rewarded by the panoramic views at the summit. The descent takes you down single-track paths through alpine meadows and undergrowth to the Col du Chaussy.
