The trail starts from the car park at the end of the road behind the Ailefroide campsite, which is very small.
(S/E) Set off at dawn, or even earlier, as the path is not tricky. Head to the bottom of the car park, following the usual signs.
(1) Turn left, following the signs for the Sélé and Pelvoux refuges. The trail is in the woods.
after 800 m, with very little climb (100 m), you will reach a fork in the path.
(2) Turn left to cross the footbridge that leads to Clapouse, leaving the paths at the bottom of the Vallon du Sélé on your right, which lead to the two refuges. Take the well-marked path that starts to climb quite quickly. There are no particular difficulties, but you need to start paying attention.
Chamois are likely to be nearby and will move away. Do not startle them; keep an eye on their movements.
Do not stray from the path, as there are some rocky outcrops on your left as you climb.
Climb up to the hump just below the 2,200 m mark, a 600 m climb. You can stop and take a look around.
(3) Begin the descent via the same route to return to the car park (S/E).
