Beautiful drive through the high Alps - but make sure your car is a manual. We had some smoking brakes by the end of it! (Also make sure none of your passengers get carsick...with 36 switchbacks, that makes for a dicey drive.)
But overall - WOW. This was spectacular and worth the 30EU toll to get on the road. A total feat of engineering. Stop at any of the pull-offs for scenic photo after scenic photo. I didn't think it was essential to go up the narrow cobblestone road to the *highest* peak on the Alpine road (it's pretty much the same view, you know?) but the store up there does sell marmot fat in a jar, apparently a highly prized Alpine home remedy for dry and wrinkled skin. Who knew.
