This offroad mountain road in the French part of the Alps will give you the chills. The views are breathtaking, this col will take you up to 2780 meter above sealevel or you can take the famous Parpaillon tunnel. The handcrafted tunnel located at an altitude of 2637 meter and 520 meters long has given many bikers moments to remember. Visit the tunnel in early spring and the water will be greeting you till the knees and if you're lucky you'll even find some very frosty slippery surface inside.
