Starting Point & Village
Starting point: Refuge Cosmic 3613m Village: Chamonix
Ascent & Route
First, we ride down to the Col du Midi, from here it goes up the northwestern flank of the Mont Blanc du Tacul, with the splitboards in hike-mode. Becoming increasingly steep we decide on a suitable place to walk on with rope and crampons. The terrain is around 35-40° and interspersed with crevasses. The best way is always changing. However, we checked the best ascent line the day before from the Cosmic hut, as you could do as well.
Descent & Variants
As ascent and then on the Mer de Glace. Known as the "Vallée Blanche" the descent from Aiguille du Midi to Montenvers normally tracked as a slope. But anyway take care because there are vast crevasses and you move in challenging alpine area. Special care is required on the NW slope of Tacul!
At the end of the descent you will find some vertical ladders to get back to the railway and than to Chamonix.

Map Explanation
- Slope inclinations are a very important criterion in avalanche risk management. However, slope inclination alone should never be the sole criterion!
- The resolution for Austria and South Tyrol is based on a digital terrain model (DTM) with 10m resolution. Outside these areas, accuracy is significantly lower.
- A map can only ever provide a limited view of real conditions.
