Start point (S) from the "theatre de verdure" car park, 100m to the left, behind Robion church.
From the car park (1), take the road towards "Le Boulon" "Les Taillades" and after the Fontaine du Temps car park, take the Boulon Haut path, an uphill paved road (yellow waymarks)
After heading downhill, they'll be a sign "Le Boulon" (2) leave the road taking the path that leads downhill to the left towards "Le Castelas".
This wonderful trail rises through the cliffs in a semi rock tunnel giving you an astonishing view over Cavaillon and the valley.
Once you've arrived at Castelas (3) take a left towards "Le Pin de Maillet". Be careful, the trail isn't very clear but has yellow waymarks. Stay alert so as not to get lost. At the next two signs, continue towards "Le Pin de Maillet".
Once you reach the sign "Le Pin de Maillet", keep going straight ahead towards "Le Quillot". When you get to the sign "Le Quillot", continue towards "Maubec" and "La Draille de Maubec" 50 m further, you'll reach the "La Draille de Maubec" and "Des Frères Nouguirs" sign (4). Ignore this sign and follow the uphill trail to the right. You're now leaving the yellow waymarks but several cairns show the way. This path takes you up to the ridge above the Vallon de Sapine and leads to another track (5), which allows you to catch up with the yellow waymarks a bit further uphill. Once you get to a wide esplanade (6) acting as a roundabout for hunters' cars, go up the large path to the left going past the weather station. Furthr along, you'll come across cairns all the way downhill. This path leads directly in front of Mont Ventoux. After completing the descent, you'll come across the GR6-GR97 (8), you'll need to head left towards Maubec (9), the GR leaves the road and rises over the camp site. When you get to the "La Draille de Maubec" sign, keep going strait heading towards "Robion".
Once at the sign "Cimetière de Robion" (10), take a left towards "Robion""Théâtre de Verdure". Leave the GR to catch up to the yellow waymarks once again. Once you get to "l'Avenue du Luberon", go back up the road to the left to find the car park (1).
