Park at the Grand Vallat car park on the edge of the D201.
(S/E) Cross the bridge and take the path immediately on the right. Ignore the paths on the left and right and keep heading north as you climb up the Gorges d'Oppedette. Continue for about 2.5 km until you reach the Aven de l'Échelle.
(1) Turn right to take the iron ladder, which is very sturdy; it is more like a staircase. The descent that follows is difficult but there are solid handrails to hold on to.
(2) Cross the river and head north-east for about 350m, then turn right onto the path that climbs up to the viewpoint. The climb is tricky but the handrails ensure your safety. You will arrive at the ridge at the Belvédère car park.
(3) Turn right, then right again 20 metres further on onto theGR®97(white and red markings). Follow this path to the D201.
(4) Cross the road and continue straight ahead on theGR®. Follow the departmental road for about 150m, cross it, then rejoin it one last time just before the car park. Turn right to return to the car park (S/E).
