The Buclet Lake is a small and tranquil alpine basin located in France, near Le Bourg-d’Oisans, within the suggestive scenery of the Écrins National Park. Immersed among woods and alpine peaks, this body of crystalline water is a popular destination for fishing and for relaxing walks away from the most intense tourist flows. Often confused with the more famous Lac du Bourget due to phonetic similarity, Buclet offers an intimate and silent environment, ideal for observing the reflections of the surrounding mountains. Its strategic position near the great alpine passes makes it a perfect stopping point for hikers and cyclists exploring the French Alps.

There are no crowds here, just you, the mountain, the wind, and the sensation of pedaling on one of the remote peaks of the French Alps. The summit, at almost 2,000 meters, offers a 360° panorama that erases fatigue and ignites the cycling spirit.

The bike path is not accessible throughout because the river has washed away parts of it. It is also not crossable on foot.

I'm 12 and rode for the first time when I was 10. It's my favorite Alpine climb. All I can say is that it's best to take a break in the corner so you can fill up your bottles and go to the toilet if necessary.
