We climbed the route on the 6th of June and we left at 2.00 o' clock the Grand Mulet refuge and arrived at the Vallot bivouac at 7.00 o'clock and skied from there down to the Plan d'Aguille. Due to quite some snowfall the days before we had find our own route and it was very, very cold. Fortunately it was a clear sky with a beautiful sunset but there was a very cold northerly wind so that we could not make it to the summit of the Mont Blanc. But skinning and skiing conditions were perfect and no problems at all with crevasses. We heard a number of avalanches coming down but were relatively small and not really worrying.
I have to say that the route we took was more towards the west than is described as the normal route on this page. I marked the route red on the image I added.
Really long, so tends to be monatonous. But impressive glacial scenery in the middle part. Then at the Vallot Refuge, most remove the skis for the last long bit on the ridge, although in hindsight I'm not sure why we didn't try to ski the North face!
Skiing down is not very steep but was pleasant with fresh pow conditions.
The traverse from the Bossons glaciar to the Midi midstation was a long one, involving taking off the skis a few times - not much fun.
