Col de l'Izoard is one of my favorites. Staring from Briançon you wind your way up the canyon. this one just keeps getting better and better. Once over the summit, you are in a lunar like setting, unlike anything I have ever seem. I my view, this route should be on your bucket list if it's not there already.

Note Nov 2012- according to Google this road is closed right now on the north ramp- hence the full rout is not showing now.
