Very steep descent (or climb, depending on your direction) passing large cliffs and rock faces next to the road. This pass connects the large town of Cluses to the high mountains and opens the doors to several possibilities for cool road bike routes.

As of June 25, crossing from both sides is not possible due to construction work. It doesn't look like this will change anytime soon.

I recommend the climb via "Nancy sur Cluses", a good winding climb with gradients of 13-14%, I saw a few French cycling clubs pass me and take this route :-) With luggage on the racing bike it's a real challenge (for the Route des Grandes Alpes - an insane test start).
