To get to the start, coming from Nyons, take the first road on the right after the tunnel and a few metres further on, turn left into the car park.
Sporadic yellow signposting.
(S/E) From the car park, turn left onto Route de Châteauneuf-de-Bordette, pass the church and reach the bridge on your left. Cross the Eygues and, as you leave the bridge, continue to the right towards Châteauneuf-de-Bordette.
Go over a small bridge with a small fountain and a flower box on your left. Find the start of a small path rising to the left just after the next house. This starts at the foot of a stone arch that serves as the entrance to the house.
(1) Five metres later, at the end of the low wall, climb the few steps to the left and continue along the path, which veers right along the edge of the cliff. Reach a track and continue uphill. At the plateau, follow the track that climbs to the right and joins the ridge. Continue to follow the ridge until you find the start of a path to the left, where the track curves to the right and leaves the summit.
(2) Continue along the path that follows the ridge, which joins a track that continues up to the summit.
On the way up, ignore the yellow markings and fork right. This takes you along a faint path a few metres below the ridge, for around a hundred metres, to reach the summit again at the level of the track.
(3) At the end of the track, continue along the path that goes deeper into the undergrowth, still following the summit. After a slight descent, begin the final climb to reach the Monts d'Autuche ridge. Almost at the summit, reach a small clearing when the path veers to the right and runs almost horizontally.
(4) Find the slightly hidden start of a small path on the left. Follow it through the boxwoods until you reach the rocky promontory on a downhill slope.
(5) Enjoy the view, then return to the previous junction.
(4) Continue straight ahead and begin the descent that follows the summit. Notice two successive red "Chasse" signs just before you reach a flat area and find the start of a path on the left.
(6) Before following the path, walk back and forth across the road for a few metres to get a view of Mont Ventoux.
On your way back, turn right and follow this path, which continues along the contour line to a small pass.
(7) Almost cross the flat area and spot a pine tree with a trunk that splits into four or five "small trunks" about 50 cm above the ground. Turn left at 90° and find the path that begins the descent to the bottom of the valley. Be careful, as the valley is sunken and very rocky, it is also used to drain off water in wet weather. At the end of this hundred-metre stretch, continue on a more pleasant path away from the bottom of the valley until you reach the next junction.
(8) Ignore the start on the left (not shown on the IGN map) and turn right into a hairpin bend.
(9) At the junction with a transversal path (not shown on the IGN map), turn left. Ignore the start of a small footpath on the left (not shown on the IGN map) and continue downhill until you reach a track.
(10) Follow this to the left, rejoin the tarmac and continue downhill to the village of Les Pilles. Cross the Eygues back over the bridge and take the road to the right to find the car park (S/E).
I've also added the precision to WP6.
