Season notes from our guide
The park gives late June to mid-September as the best season. Most refuges are staffed from mid-June to mid- or late September. In June and early July snow often lies on the north side of the high passes, especially below the Col de la Muzelle and the Col de la Vaurze, and ice axe and crampons can be needed: ask the refuges about conditions before you set out. July and August are the busiest months and afternoon storms are common, so start early. September is quieter, but check that every refuge you need is still open.
