This couloir gives you an aesthetic view on the wild side of Monte Rosa, it's not an easy line though! It requires mountaineering skills since you'll need to rappel down an ice fall (40m).
This line requires good knowledge of the snow and the mountains.
In order to access this line you have to skin up towards Passo Bettolina and then go down to reach a valley.
Here the first rocky slope will give you access to the couloir.
