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.

June 15, 2022,Alpe d'Huez lohnt nicht, aber Col de Sarenne und Balcon d'Auris!

Alpe d'Huez was full of construction sites😣, the Tour de France is coming here in four weeks. I'll stick to it: you don't need Alpe d'Huez, there are many passes that are at least as beautiful with less hustle and bustle and construction noise. My plan was to do it during the off-season during the week (fewer motorcyclists and tourists), …
