District:
Park in the car park of the Abbaye Notre-Dame de l'Annonciation, on the D938, coming from Carpentras or Malaucène. The sign clearly indicates the exit to take.
(S/E) Return to the crossroads marked by an oratory.
(1) Take the track on the left, uphill, to reach the hamlet of Les Ambrosis.
(2) Leave the path on the left and continue on the path that climbs towards the Clairier ridges, along the goat fence. Turn right onto a small, fairly steep passageway for about ten metres, then onto an easier path through the scrub and scree. The ruins of the ancient oppidum will be on your right. Stay on the ridge, ignoring the paths that descend to the right, before arriving at the junction with theGR®® at the Clairier crossroads.
Enjoy the beautiful view.
(3) Leave theGR®® and take the path opposite that climbs towards the Gippières ridges. Ignore the paths that descend to the right and left, stay on the ridge until you reach the junction with a path in a hairpin bend.
(4) Turn left at a 90° angle and continue straight ahead on this beautiful path through the woods until you reach the junction with theGR®® 4.
(5) Take it to the right until you reach the signpost for Les Issards.
(6) Turn left here and follow theGRP®® des Dentelles de Montmirail, towards Le Barroux, until you reach the crossroads with the signpost for Le Bois Long.
(7) Take the road on the left, being careful as there is some traffic, and arrive at the old Barroux Aqueduct, which has been partially restored but is not very visible on the right. A small path on the right leads to the circular arch.
Retrace your steps and continue right on the road that climbs slightly until you reach the crossroads leading to the Ambrosis farm.
(8) Stay on the road and continue on a slight downhill slope to reach the car park of the Abbaye Notre-Dame de l'Annonciation (S/E).
