From an obscure and majestic fir grove untouched by logging, the trail becomes clearer as it winds its way along the southernmost grassy ridges of the Diois, culminating in the summit of Duffre and its panoramic view of the Ventou...
The Natura 2000 site "Pelouses, forêts et habitats rocheux de la montagne de l'Aup et de la Sarcena" (grasslands, forests and rocky habitats of the Aup and Sarcena mountains) is home to typical mountain avifauna (Montagnard Venturon, woodchat, spioncelle pipit, rock blackbird, etc.). A population of black grouse can be found on both slopes, and the Tengmalm's owl has been spotted in the beech and spruce woodlands. The area is also exceptionally rich in botanical diversity, with 450 plant species recorded, including three listed in France's "red book" of endangered flora: Dauphiné saxifrage, sauze cytise and tiny-flowered forget-me-not.
1/ At the entrance to the resort parking lot, take the path up the embankment.
2/ Take the first path to the right on the slope. At first, it runs alongside another track above and the resort access road below.
3/ In the hairpin bend, continue straight ahead on the track. It leads to the Pré Pourri hut parking lot (alt. 1409m).
4/ Cross the clearing and take the path into the undergrowth. As you approach the rocks, let go of the discovery trail on the right and turn left onto the path that joins the Sarcena ridges.
5/ Turn left on the track that climbs between rocks and box roots. Continue along the ridge over the high grasslands of Montagne de l'Aup. Reach a cross and then the Duffre summit (alt. 1757m).
6/ Descend to the collet and climb to the summit of Pyramide. Continue downhill along the ridge to Pas la Lauze (alt. 1553m).
7/ Leave the ridge and take the left-hand path down through the grass. It veers left to reach the Bergerie (alt. 1510m).
8/ Descend to the right towards the station, along the MTB track and "Trotin'herbe". Heading due north, it takes you back to the starting embankment. Then join the parking lot.
Free access.
