Normal Route via the Glacier Blanc and the Brèche Lory

The south face is a more committing and technical way to the summit than the normal route. It is a classic alpine face climb with steep snow and ice sections, mixed passages, and significant exposure. Conditions are highly dependent on temperature and snow stability, and the face can become dangerous with warming or fresh snowfall. Parties need solid cramponing, ice-axe technique, and efficient movement on steep terrain. It is generally less straightforward to navigate than the normal route. Descent is commonly made by the normal route if conditions allow.

The north face is a major alpine objective and substantially more serious than the standard route. It is a steep, technical face climb with sustained ice and mixed climbing, and it is exposed to objective hazards such as rockfall, icefall, and changing snow conditions. The route demands strong technical ability, efficient protection, and good judgment about conditions. It is typically attempted by experienced alpinists only. The line is much less forgiving than the normal route and may require a complex descent plan. It is a true high-mountain face climb rather than a glacier walk.
