Park at Col du Festre.
Preliminary remark: the route to Col des Aiguilles follows theGRP® marked trail shared by the Tour du Dévoluy and the Tour du Buech to the west and presents no danger except for the tricky passage at the Saute Aure waterfall, which can be slippery in wet weather.
(S/E) Take the wide track, markedGRP® Red and Yellow, through the Vallon de Serre Noir.
(1) At the end of the sheep park, ignore the fork to the right (north-west) which leads to the Cabane de la Rama and continue straight ahead on the path which climbs through the mountain pastures to a large shepherd's hut at a place called Le Selenq, the crossroads for the return route.
(2) Continue straight ahead on theGRP®, heading north then west to pass the Cascade de Saute Aure waterfall. Be careful, as this is a slightly tricky passage. The trail then opens out into a wide valley, follows the meandering stream and, before the Fontaine du Roy fountain, joins the crossroads of the return branch at a place called Prés du Col.
(3) Continue west on theGRP® to easily reach the Col des Aiguilles (2,009 m).
(4) Return via the same route, descending the Vallon des Aiguilles to Prés du Col.
(3) From there, the off-trail route requires good visibility and a sense of direction.
Cross the meadows towards small pass (1,942 m), which is clearly visible, heading south-east.
The climb is easy in the low vegetation and the passage to the small pass is easy to find.
From the small pass, walk along the hillside, still heading south-east, towards the Col de Darne (1933m). Reach the pass.
(5) Continue south-east to the summit of Chauvet, following the ridge, rather below, on the east side.
The climb is steady and presents no difficulty.
(6) From the summit (2062m), return by the same route, slightly below the ridge, to reach the Col de Darne.
(5) Descend to the right into the north-east facing valley. Pass by the Fontaines Froides (Cold Springs) towards the sheep pens and the shepherd's refuge. There is no path at the beginning, but from the springs onwards, you will find animal tracks that are easy to follow.
Reach the fenced enclosures, go around them on the left and rejoin the marked path you took on the way up.
(2) Turn right onto the path you took on the way up to reach the car park (S/E).
