Start of the walk from the Aire L. Peysson, 500m behind the village of Auribeau.
(S/E) From the car park, head back down to the road and immediately turn right (yellow markings) onto the track towards Mourre Nègre.
After passing a house, the track becomes a path and quickly rises into the undergrowth.
(1) Continue to the left (yellow markings), climbing up a ledge through the Vallon de la Font Jean de Martin. Pass another valley, then a third, the Vallon des Trois Èves, before reaching La Marauvière, 712m (marker).
(2) Continue to the right (yellow markings) and tackle a steeper climb above the valley. After passing a small pass near the 861m marker, descend into a small valley where you join a forest track that leads you to the ridge.
(3) When you reach a larger track, follow it to the left (yellow markings) to reach the Basse de Cabrières pass at 1024m.
(4) From this pass, turn right in a hairpin bend (yellow markings) onto the path that climbs along the ridge towards Mourre Nègre.
Pass an antecima before descending to the track at the foot of Mourre Nègre. One last effort and you reach the summit, 1125m.
(5) Go around the base station to the left and down the faintly marked path on the north side heading north-west, facing the Ventoux (be careful to keep the power line on the left).
Then enter the forest to join the main track visible below.
(6) Turn left, again following the yellow markings on the path that climbs to the right of the track.
Pass by a shepherd's hut (locked) and reach the Jas du Brémond, 994m.
(7) Turn right down the Vallon de Roumi towards Auribeau.
Cross the track 3 times, following the yellow markings, then walk along it for around 100 metres to reach the foot of the former Château de Saint-Pierre.
(8) The signs indicate a path on the right, but you can go back and forth to the fort and the chapel for a beautiful view of the valley and Mont Ventoux.
Return to the track and continue left along the path that runs alongside a few lavender fields just before you reach the car park (S/E).
