In Collias, park your car in the paid parking between the bakery and the André Clément hall.
Yellow waymark
(S) Exit the car park, turn right and follow 'l'avenue du pont', cross the bridge, then take the first street to the left (Chemin de Saint Privat), heading towards the Hermitage and 'Ron de Fabre'.
The paved road will follow the Gardon River for a while, leading you to a sign indicating 'Ron de Fabre'. When arriving at this crossing, take the dirt track to the left of the tavern heading towards the hermitage and Cantadu. This track will later turn into an paved road leading to a crossing. Turn right on the Hermitage path (chemin de l'Ermitage), 20 m further, a stoned cross marks the Cantadu crossing.
(1) Continue straight ahead to the Hermitage, don't follow the track to the right (this will be the way back). The track will steadily wind through holm oaks and boxwoods, in the hermitage's valley and crosses the dry streambed several times.
Once you get to the foot of the hermitage, forget the path that goes left (not marked on the map), keep going right, heading to the hermitage (2) after climbing a few stone steps.
At the top of the site, the track will turn left through the rocks towards Cabrières and Le Grand Serre. Go passed another stone cross, then, 300 meters higher the trail leads to a track marked 'Le Grand Serre' .
(3) Take the track to the right leading to Collias and Contadu, continue on the main path with yellow waymarks paying no attention to all the little trails forming on either side. The path will wind uphill, then slowly downhill reaching a T crossing. Turn right to get back to the Cantadu stone cross.
(1) Turn left, then left again 50 m further on the Saint-Privat path. Take the same route as when you started to gain the car park.
