This is a superb, remote, challenging alternative mountain biking route to Plateau des Glières. Fun. Map, photos, etc.
If you don’t like a little bike pushing and carrying then you best ignore this post.
Back in May, we hiked up to Chalet des Auges above Col des Glières. We were astonished to see a mountain biker there. Upon interrogation we discovered that there is a terrible quality, old road up the back way, starting in Entremont.
