Starting point is L'Airette (1239 m). This place can be reached from Ardon following a well marked path and a rough road in 2-3 hrs. Consider taking a car or a moutain bike if you intend to go back to L'Airette. There's also a good path from Motélon (on the road to Derborence), this access takes 1-1.5 hrs.
A good path leads to Chalet d'Einzon and the ruin at Itre du Bouis. From here you can ascend the enormous NE side without any given route. This is very monotonous in late summer (rubble), but in June, you can usually except to find the rubble covered by snow (start early for a great descent!). Shortly before the summit, you reach the east ridge. Just before the summit, a notch demands some easy climbing (II).
Patience and a stoic character are helpful for this route.
