Yeah, the top of the big climbs (with snow walls) are amazing....
Midweek stage starts/finishes are a great place to get close to the action. There are smaller crowds than at a weekend
In my experience it is a smaller race than the TdF so restrictions are not as severe.
I'm going to see the Giro this year and heading for the stage up the Stelvio pass. Has anyone done this before? Looks like I can only get a hotel in Prato, but how do you get to the climb. I think you cannot park your car on the climb, but are there any designated places the organisers want you to park.
