Road opening scheduled for June 13, 2025

Scheduled opening of the access road to the Iseran pass: Friday June 13, 2025 (2nd Friday in June).

Europe's highest road pass (2,764m), clearing snow from the Iseran is a major undertaking, requiring several weeks of work on both sides of the pass. Snow depths often reach 8 to 10m in some areas (notably at the "pont de la neige" on the Bonneval sur Arc side).

The pass is usually open to traffic from the 2nd Friday in June to the 1st Monday in November.

*⚠ opening dates may vary and the road may also be closed to traffic, even in midsummer, depending on the weather.
