I have just had an excellent four days traversing the Alps from Bourg St Pierre to Arolla via the Vallsorey, Chanrion and Dix huts. The route had a bit of everything; walks through alpine meadows, long glacier sections and pitched climbing to gain the Plateau Du Couloir.
The Plateau Du Couloir is crossed between the Valsorey and Dix Huts. Currently, conditions on the descent of the Plateau Du Couloir towards the Dix Hut are not very good. The descent is dry making rockfall an issue and can not be recommended.
