Gervasutti Pillar

This is the standard and best-known way to climb Mont Blanc du Tacul from the Chamonix side. The route is a classic alpine snow-and-glacier ascent with objective hazards from crevasses and serac fall, especially on the approach across the Glacier du Tacul. Conditions can vary significantly with snow cover and avalanche risk. The climbing itself is generally moderate, but route-finding on the glacier and timing are important. It is commonly used as an acclimatization climb in the Mont Blanc massif. The route is normally done with glacier travel equipment and rope team techniques.

The Cosmiques Route is a well-known alpine route on Mont Blanc du Tacul and is more technical than the normal snow route. It typically combines steep snow, ice, and short mixed sections, with conditions strongly dependent on the season. The line is exposed to rockfall and serac-related hazards in the lower and middle sections. It is a popular objective for climbers seeking a more demanding ascent from the Aiguille du Midi area. The route requires solid cramponing and ice-axe technique, and often protection on mixed terrain. It is usually climbed in good conditions and with an early start.
