The ski resort of Bonneval-sur-Arc is open until April 30 and reopens in December but you can still ski not far from mid-June to mid-July.
Explanations :
In winter, the resort of Val d’Isère, although partly on the commune of Bonneval-sur-Arc is distant from a few minutes of helicopter, a few hours of ski touring or … 220 Km of car, it is necessary in this case to circumvent all the Vanoise massif!
On the other hand, in summer, when the Iseran pass is open, it is possible to ski on the Grand Pisaillas glacier just at 13 kilometers of pretty road.
