A brief description
Start from Cogne and reach Lilliaz on a nice dirty road inside the wood. From Lilliaz up on an asfalt road for some Km, suddenly you will enter in a beautiful valley and the road become dirty. It's a long path and you will see the scenario changing slowly around you.
After some km you will leave the dirty road for a single trail. Then the last 200 mt of elevation you'll need to walg till the pass.
