Right problem on the West face of the boulder of Prince de ce Monde. Sitstart in the pit (without crash-pad) as for Prince Noir but continue in the right face with crimps and exit by a dyno.
Access : from the parking lot of Le Carrefour du Rocher des Princes, follow La Route de Montmorin (blue path) for 100m, take a small path to the right before the bend and follow that one up to the crest.
