The three Chamrousse climbs

Discover the three different routes that make up the Les Fous de Chamrousse challenge: via Seiglières, Prémol and Luitel.

The main climbs

The summit: Col de Chamrousse (1,795 m)

All three routes finish in the same place: the Col de Chamrousse, the challenge's high point at 1,795 m (nearly 1,800 m), just above the Chamrousse ski resort. Once you're in the resort, the col sits a little higher up: keep following the road as it continues to climb to the summit sign.
