Descente du col de la Sarenne

Very technical descent, I recommend using bikes with disc brakes.

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.

Descent from Col du Sarenne

Highlight • Mountain Pass

A very difficult descent, the asphalt is a bit undulating and you pick up speed very quickly, with disc brakes I had to stop a couple of times to let them cool.
