Park in the car park at the end of Place de l'Étang in Cucuron on the right below.
(S/E) Leave the car park and turn right onto Rue Bérard du Roure, which climbs and becomes Chemin de l'Hermitage. It continues opposite to climb up the valley (yellow markings).
(1) At the end of this road, at a three-way intersection, turn left onto the path. Stay on the main path until you reach a crossroads. Ignore the path on the left and continue straight ahead. The path narrows and, before you reach an area of terraces planted with fruit trees, take the path on the left that climbs up to the Chapelle de l'Ermitage, perched on the hill.
(2) Go around the chapel on the left and follow theGR® (red and white) marked path which climbs northwards.
(3) When you reach a track, follow it to the left for 50 metres, then leave it and take a small, barely visible path on the right, which climbs up to the Ferme de la Tuilière.
(4) At the Ferme de la Tuilière junction, ignore the signpost on the right and continue climbing for 700 metres.
(5) At the intersection, leave theGR®9trail on the right and turn left towards the Fayette - La Glacière valley (yellow markings). After walking for almost 2 km, leave the path that branches off to the left and continue straight ahead uphill.
(6) 300m further up, look for a cairn marking a small, fairly steep path climbing up to the right. This leads to the ridge.
(7) Once on the Luberon ridge, take the path on the left that follows the ridge and, after a final steep climb on the left, reaches the summit of Mourre-Nègre, the highest point in the Luberon.
(8) Descend from the summit and take the track on the left which leads to a crossroads.
(9) Follow the track on theGR®92to the left towards Jas de Brémond for about 7km, staying almost entirely on the ridge line.
Ignore the next two crossroads and continue straight ahead to find the Hamourralhadou marker.
(10) Continue for 200m to Les Estrugets and turn left. Follow the track for another 3km to the Lou Pas deïs Ansarris crossroads.
(11) At this junction, take the path that descends to the left into the valley towards Vaugines.
(12) Once on the road (Chemin de Vaunières), rejoin theGR® and turn left for 300 metres, then left again onto Rue des Grottes, which leads to the village square in Vaugines.
(13) Continue right on Rue de la Mairie, then quickly left onto Rue Basse. Then turn left onto Rue Capello for a few metres and continue right onto Rue Haute. When it leads to a small square, make a zigzag right-left turn to find yourself on Allée de l'Église.
(14) Take the path that goes around the small chapel on the left and goes up through the olive trees. Ignore the paths on the right and left to reach Route de Vaugines (D56).
(15) Turn left to reach the Guet crossroads on the D56. Turn right and then immediately left onto Chemin de Vaugines. After 500 metres, turn left onto Chemin de Gabarru, which leads back to Place de l'Étang and the car park (S/E).

Perhaps you could indicate that it follows the GR? (But I think we are at a GR intersection at this point).
