Moderator’s update as at 16 March 2020: reviews of this walk indicate that the aqueduct has collapsed.
(S/E) From the Saint-Roman Abbey car park, take the DFCI14 (barrier) for 800 metres (yellow markings) to the main junction.
(1) Leave the DFCI14 and turn right, then immediately left, and stay on this path until you reach the water tower.
(2) At the old water tower, retrace your steps to the old small dam. At the cairn, take the steep climb directly in front of you (caution: this climb is very steep and consists of large, rather unstable stones) and continue straight on until you rejoin the DFCI. Turn right for about 300 metres round the bend and, at the cairn, take the small path that descends towards the aqueduct.
(3) At the aqueduct, turn left and take the DFCI17 (after 200 metres, you can either stay on the DFCI or take theGR®® which runs alongside it; the distance is the same and the rest of the route remains unchanged).
(4) At the yellow signposts, take a round trip to the “Rocher de Triple Levée”. Turn right towards “Rocher de Triple Levée” (steep climb in places). Walk round the rock on the left to see it from all angles, then head back down to the DFCI17 and turn right. Follow the DFCI17 as far as the cistern and turn left (walk past the cistern). Continue straight on towards “l’Aiguille”, ignoring the path that branches off to the right a few hundred metres further on.
(5) Take the path climbing to the right, markedGR®® in red and white, until you reach a track suitable for vehicles, then turn left towards l’Aiguille. Approach the orientation table from the right.
(6) When you reach the information board, take the narrow path leading down to your left – the “goat path” – to the wayside cross.
(7) At the wayside cross, take the path on the left to go round the abbey at the bottom. Walk past an old ruined building and continue straight on until you rejoin the DFCI14. Turn right onto the DFCI to reach the car park (S/E).
