A classic and well-documented alpine route on La Meije, usually climbed from the Promontoire Hut. It follows the prominent south-western ridge system toward the summit of Pic Oriental. The route is long and serious, with sustained scrambling and climbing on exposed rock and mixed terrain. Conditions can vary greatly, and route-finding is important in the upper sections. It is generally considered one of the standard ways to reach the summit of the peak. The route is exposed to rockfall and objective hazards, especially in warm conditions.
