Parking 1 km after Saint-Antonin-sur-Bayon on the left of the CD17.
(S/E) Take the path that heads back towards Saint-Antonin and quickly turn north-east towards the Sainte-Victoire cliffs.
(1) When you reach elevation 555, leave the brown-marked trail from Refuge Cézanne on your left and continue straight ahead. The trail turns west for the first time and, after 300 m, heads east again to an old marble quarry.
(2) After visiting the marble quarry, retrace your steps and follow the brown markings on the right, which lead to the Refuge Barthélémy Baudino.
(3) Just to the right of the refuge, continue along the brown-marked trail, crossing large rocks and following markings that are not very visible. After this rocky section, continue on, ignoring the trail that climbs left towards the ridges, to reach the Hermitage of Saint-Ser.
(4) After visiting the chapel, take the path just to the right, marked in red, which climbs towards the ridges.
This is the most difficult part of the route, with a particularly tricky section over slippery rocks, fortunately secured by chains.
(5) Once at the top, turn left towards the west onto theGR® 9, which follows the mountain ridges. Pass by the Brèche de Genty, then the Col de Vauvenargues, the Col de Suberoque, etc., to reach the Priory.
(6) Just before the Priory, you can climb up to the left to the Croix de Provence for a 360° view. Visit the Priory, then begin the descent towards the west.
(7) 200 m further on, leave theGR® 9, which descends to the right, and continue straight ahead on the blue-marked trail (Sentier Imoucha).
Alternative route: At an elevation of 767 metres, at Pas du Moine, you can take a path that descends to the left towards Refuge Cézanne, but with some slightly more challenging sections.
(8) When you reach Pas de l'Escalette, at an elevation of 686 metres, turn left, heading south, onto the red-marked trail that descends towards the Refuge Cézanne. The first part of the trail is on fairly steep limestone slabs on which steps have been carved.
(9) After visiting the Refuge Cézanne and the Chappelle du Trou, head east on the brown-marked trail, which climbs steadily towards the Oppidum Untinos.
(10) At the top of the climb, turn right, heading south towards the oppidum, then, shortly afterwards, take a path on the left that descends towards the Deux Aiguilles car parks.
(11) Follow the road east for 650 m to return to the starting point (S/E).
To avoid walking along the roadside (there is no hard shoulder), you can follow a track running parallel to the road about 20 metres to the left.
