To reach the start, coming from Nyons, take the first road on the right after the tunnel and, a few metres further on, head towards the car park on the left.
Sporadic yellow markings.
(S/E) From the car park, turn left onto the Route de Châteauneuf-de-Bordette, walk past the church and head for the bridge on your left. Cross the Eygues and, as you come off the bridge, continue to the right towards Châteauneuf-de-Bordette.
Cross a small bridge with a little fountain and a flower box on your left. Then look for the start of a small path leading uphill to the left just after the next house. This path begins at the foot of a stone archway which serves as the entrance to the house.
(1) Five metres further on, at the end of the low wall, climb the few steps on the left and continue along the path which turns right along the edge of the cliff. Reach a track and continue uphill. At the flat section, follow the track which climbs to the right and joins the ridge. Carry on along this track until you come to the start of a path on the left, just as the track curves to the right and leaves the summit area.
(2) Continue along the path that follows the ridge; this joins a track that continues the ascent along the summit area.
On the ascent, ignore the yellow markings which suggest turning right. This leads along a poorly marked path a few metres below the ridge for about a hundred metres, before rejoining the summit section at the track.
(3) At the end of the track, continue along the path that leads into the woodland, still following the summit ridge. After a gentle descent, begin the final ascent to reach the ridge of the Monts d’Autuche. Almost at the summit, you’ll come to a small clearing where the path turns right and runs almost level.
(4) Look out for the slightly hidden start of a small path on the left. Follow it through the boxwood until you reach the rocky outcrop via a gently sloping path.
(5) Take a moment to enjoy the view, then return to the previous fork.
(4) Carry on straight ahead and begin the descent that follows the summit area. You’ll clearly see two successive red ‘Chasse’ signs just before reaching a flat stretch, where you’ll find the start of a path on the left.
(6) Before following this path, take a short detour of a few metres straight ahead to enjoy the view of Mont Ventoux.
On your return, turn right and follow this path, which continues along the contour line to a small pass.
(7) Cross almost the entire flat stretch and look out for a pine tree with a trunk that splits into four or five “small trunks” about 50 cm above the ground. Turn 90° to the left and find the path that begins the descent at the bottom of the valley. Caution! As this path lies in a hollow, it also serves as a watercourse in wet weather and is very rocky. Once you’ve passed this section, which is about a hundred metres long, continue along a more pleasant path, moving away from the bottom of the valley until you reach the next fork.
(8) Ignore the path branching off to the left (not shown on the IGN map) and take a hairpin bend to the right.
(9) At the junction with a cross-country path (not shown on the IGN map), turn left. About fifty metres further on, ignore the small path branching off to the left (not shown on the IGN map) and continue down a gentler slope until you reach a track.
(10) Follow this track to the left, join the tarmac road and continue the descent to the village of Les Pilles. Cross the Eygues again via the bridge and take the road on the right to return to the car park (S/E).
I've also added the precision to WP6.
