Sarenne Pass

Highlight • Other

One of the most epic climbs I’ve ever done — a hidden paradise, not well known, unlike the more popular climbs. In my personal opinion, it’s a much more epic ascent than Alpe d’Huez. Highly recommended

Sarenne Pass

Highlight • Mountain Pass

The Col de Sarenne is one of the mythical passages accessible from Bourg d'Oisans and Alpe d'Huez! Culminating at nearly 2000 m, its passage requires a good physical condition whether it is during a bike outing or a hike.
