The route begins from the Cosmiques hut, not far from the Col du Midi. From the Colle we begin to climb up in northern, long the normal route of the first of the three “Mont Blanc”. Passed a first section with many seracs the ascent go on rightwards reaching the shoulder of Mont Blanc du Tacul. On the opposite side we cross reaching the Col Maudit.
From here we proceed climbing on and then crossing the big glacier basin of Mount Maudit in direction of the Col du Mont Maudit (4345 m), reachable overpassing a small but steep slope around 50°. Over the Col we loose some height to reach the Col of Brenva. After a last steep climb of the Mur de la Côte we reach the top of the peak.
The descent can be done on the same way or crossing in Capanna Vallot e the Dôme du Goûter direction.
