Park in the car park of an old mill, on the edge of the D40 about 2.5 km after Saint Léger-du-Ventoux towards Brantes.
(S/E) From the car park, you will see the Saint-Basile sign indicating the direction of Brantes and Les Bernards. Take the small tarmac road on the left that climbs uphill (yellow signposting), which quickly turns into a track. In a bend, 900m higher up, the signposting leaves the track and turns left onto a path. This leads to a track at the Les Vaisses sign.
(1) Turn right towards Mont-Serein and Combe Rolland, then a few metres further on, turn left onto the red and white marked path (GR®). Continue climbing, following the markings and ignoring all the paths that branch off to the right and left. The path joins a track at the Combe Rolland sign, turn right towards Mont-Serein and Les Rouyères. 100m further on, you will reach the Les Rouyères sign.
(2) Leave the track and turn left towards Mont-Serein and Abris du Contrat.
The climb continues for 4.3 km, with beautiful forest passages and a few sections with small scree slopes. In a hairpin bend, look for a cairn on the right indicating a path to the right (this will be the path for the return journey). Leave it for now and continue onthe GR® for 150m to reach the Abri du Contrat, a small hut that serves as a shelter for hikers.
(4) Turn left onto theGR® towards Mont-Ventoux and Le Contrat. 200m further on, the sign for Le Contrat points towards Mont-Ventoux and Combe de la Mine. Follow these directions to the left.
(5) When you reach the Combe de la Mine sign, turn right towards Mont Ventoux and Les Mélèzes on a beautiful path, then 100 metres further on at the Les Mélèzes sign, continue straight ahead towards Mont Ventoux.
The path climbs into the forest, through increasingly tight hairpin bends and then over scree, skimming the D974 in a bend.
(6) Start climbing again on the stones. The trail eventually comes out higher up on the D974 at the foot of the summit.
(7) Cross the road and head opposite onto the small unmarked path that climbs towards the buildings at the summit
(8) You can take a quick tour of the facilities to enjoy 360° views of the surroundings before starting your descent.
Take the D974, which descends to the left towards Malaucène, pass two car parks and a viewpoint, and continue downhill to the left on the road until you reach a road sign warning of rockfall.
(7) At this point, the trail branches off to the right to begin the descent via the same route as the ascent.
(6) Skirt the road again and continue along the winding trail to the Mélèzes signpost, then continue straight ahead towards Mont Serein and Combe de la Mine.
(5) 100m further on, at the Combe de la Mine sign, turn left towards Mont Serein and Le Contrat.
(4) When you reach the Abri du Contrat, take theGR®9 trailto the right of the hut towards Brantes and Les Rouyères to reach the hairpin bend and the cairn you spotted on the way up.
(3) In the bend at the large cairn, leave theGR® which branches off to the right and take the small, barely visible path on the left. This path is abandoned but continues for 500 metres until it joins a track in a bend (yellow signposting).
(9) Take the path on the right that descends in wide hairpin bends for about 2 km and comes out at the three-way junction.
(10) Take the first track on the right towards Brantes and Les Rouyères, marked in yellow. The track continues flat for about 4 km.
(2) When you reach the Les Rouyères sign, continue straight ahead on the track towards Brantes and Combe Rolland, then 100 m further on, leave the track and turn left towards Brantes and Les Vaisses (red and white signposting).
2 km further down, when the path becomes flat, turn right at the crossroads and continue for 50 m until you see the sign for Les Vaisses.
(1) Leave the path and theGR® trail and turn left onto the yellow-marked trail towards Saint-Basile.
The path leads to a track on a bend. Continue downhill to the right to arrive at the car park a good kilometre further down (S/E).
