Vertical / summit day1,050 m gain · 6h
Climbed almost exclusively as part of the Trois Monts route on Mont Blanc, but Mont Maudit can also be climbed as a stand-alone objective. From the Cosmiques hut the route crosses Mont Blanc du Tacul, descends to Col Maudit and climbs the NW flank to the summit ridge — 40–50° snow with a bergschrund step. Serac hazard from the upper Tacul face.
