Ailefroide is the bouldering area for the Ecran, it lies at the head of the Vallouise valley, 18km from Vallouise and about a 30 minute drive.  The main areas are within a tumble out of your car or a short walk from the campsite.  Grades range from 4 through to 8c, the bouldering is mainly on blocks which have toppled down from above rather than eroded from the ground, however each winter the area is covered in snow so the freeze-thaw process will have an effect over time on the routes.

This is the mushroom block during the annual bouldering comp in 2004, the climber is just finishing rocco's dino 6b+***
