The walk starts from the hamlet of Kirbon. You can park on the side of the D12, just before the start of the path when coming from Trets.
(S/E) Take the path, marked in yellow, which heads north on flat ground, then descends to two bridges, the Baboué bridges, which cross the Vallat d'Ancoly and the Vallat de la Machine. The path then climbs gently for about 800 m to join another track (elevation 409).
(1) Take this new track heading south then south-east towards the hermitage of Saint-Jean-du-Puy. Follow this track for about 1.6 km, ignoring two tracks branching off to the left.
(2) About 170 m after the second intersection, take the path on the left that heads north, then east, still marked in yellow. This path then runs alongside the track and crosses it several times to take you to the hermitage. Shortly before, join theGRP® Sentier Provence Mines d'Énergies, marked in yellow and red.
(3) After the second building, turn left onto the path marked in yellow and yellow and red, which descends to a trail junction.
(4) Turn right towards "Peynier par le Regagnas", which will take you along the ridges, still following the markings. Ignore the adjacent paths.
(5) Cross the CD12 (Route de Saint-Zacharie) and take the marked trail opposite, above the track. Follow the ridge via rocky passages parallel to the track. For those prone to vertigo, it is preferable to take the track.
(6) At the crossroads, leave the double markings and follow the path opposite, which continues along the ridge and will take you to the fire lookout at the top of Regagnas. Please note: this path is used by mountain bikes with jumps.
(7) At the summit, after admiring the view, descend the road for 150 metres. Leave it on the left, at the end of the safety barriers, to continue along the ridge path. Join a path supporting theGRP® Sentier Provence Mines d'Énergies.
(8) Follow it to the right until you reach the main track with yellow markings. Following these markings, cut across the two bends and continue along the track to a fire hydrant (elevation 497).
(9) Follow the track to the right, continuing to follow theGRP® and the yellow markings for just under 600 m.
(10) At the hairpin bend, leave the track and take a path that branches off to the right. Immediately leave this path to the left to reach a game trough, after crossing a first path.
It is also possible to continue along the track and the markings to elevation 487, then leave theGRP® and follow the yellow markings on the right.
After the watering hole, rejoin the main track marked in yellow and follow it to the right for about 400 metres.
(11) Just before a slight right-hand bend, leave the track and the markings to take a path that descends to the left, heading north, then veers east after about 1 km.
(12) At the crossroads after passing through Vallat du Fer à Cheval and crossing another vallat, take the path on the right and follow it until you reach the main track and the yellow markings.
(13) Take the track on the left and head towards Kirbon and the starting point (S/E).
