This is a beautiful circuit with a significant elevation gain in altitude but without any technical difficulty. After the start on the road, you will join a monotrace trail in the forest that you will follow for almost the entire trail. The efforts on the steep slopes will be rewarded by relaunches on the heights of the "Monts d'Autuche" and an equally pleasant descent, interspersed with some portions of tracks to reach the alleys of the village Pilles.
Warning: the upper part of the "Monts d'Autuche" is not marked specifically "Trail". Follow the yellow PR hiking signs that are already there. You can also download the gpx of the circuit or the mobile app Baronnies in Drôme Provençale to embark the track.
