(2) Cross it and continue along the track opposite after passing through the barrier to keep out cars. At the end of the track, turn left onto the small road known as Chemin de l’Adrech du Deffends. You’ll reach a Y-junction at the end of this path.
(3) Keep to the right, still following the red and whiteGR® markings, cross a ford and, a little further on, join a road on the edge of the forest at a place called La Calade.
(4) Cross it carefully; leave theGR® here and take the uphill track opposite. Continue through the forest. You’ll soon come to a tarmac road. Follow it for a few metres, cut across the bend and rejoin it. Turn right off it, rejoin it once more and arrive at the car park of the Esparron-de-Verdon Emergency Services Centre.

Walk past the Sainte-Magdeleine Chapel, then turn left onto Chemin des Fourches. Follow this path until you reach a crossroads just before Rue des Fontaines, which you took on the way out.
