We completed this route in late July/early August 2025, camping in bivouacs.
The entire route is generally very well marked, and the GPX track proved to be very accurate. On the third day, we opted to go via the Col du Rosset, which is slightly lower than the Col de la Nivoletta and shortens the stage, although the climb is still steep. Finally, we decided to return to Val d'Isère from the bottom of the fours and thus finish the tour on day 5.
We encountered very little snow: only two short, gently sloping snowfields during the climb to the Col du Carro on the Italian side. This climb takes place in a very wild and unfrequented area, but the trail is well marked and the GPX track is reliable. Be careful, though: the end of the climb is very technical, with three sections equipped with ropes that are more like climbing or via ferrata than classic hiking.
Finally, regarding refuges, please note that the Chivasso is permanently closed, but you can stay at the Savoia, which is a few metres lower down (less typical). Please note that the Fond des Fours refuge has very limited capacity. Booking is compulsory, including for bivouacking nearby, and you need to book in advance as only 10 people can bivouac there.
