Park at the Ermitage car park in Saint-Gens.
(S/E) Follow the path heading south to reach the Source de Saint-Gens.
(1) Turn right, heading towards the Rocher des Trois Luisants. The path climbs steeply from the car park, but the sections are well signposted and straightforward. Leave the Rocher des Trois Luisants to one side and continue to the left until you reach the junction with the track of the same name.
(2) Take another track to the right and leave it further on, at the hairpin bend, to reach the watchtower.
(3) Head straight down towards Saumane until you reach the junction with a track: a steep 600-metre descent winds its way down, offering beautiful views of Vallescure and the surrounding cliffs.
(4) Follow this track, turning left.
(5) Keep to the right at this three-way junction, continue straight on at the next junction and begin to negotiate the left-hand bend (elevation 337).
(6) Leave the track and follow the path starting on the right. Walk round the buildings at La Mondote and head for the superbly restored semi-troglodyte farmhouse at Marculy.
(7) Resume the route by taking a downhill stony path on the left, and admire the drystone shelters in the surrounding area. You’ll come out onto Chemin de la Tapy.
(8) Follow it straight on towards Saumane-de-Vaucluse.
(9) At the entrance to the village, turn right onto Rue des Fontaines and arrive at Place de la Mairie.
(10) Continue for a few dozen metres, turning right, then immediately turn right onto Montée du Château. Pass the castle and continue along the tarmac road.
(11) Go straight on along a wide path marked by the two GR® de Pays trails, the Massif du Ventoux and the Tour des Monts de Vaucluse: yellow and red markings.
(12) Carry on straight ahead, following the markings, until you reach the Piste du Grand Puymians.
(13) Turn right, then left at the three-way junction about a hundred metres further on. Continue to the junction opposite the quarry and rejoin the tarmac road.
(14) Turn left, walk alongside the quarry and follow the tarmac road which leads directly to the car park at the hermitage (S/E).
