The Giau Pass (Passo di Giau -
http://www.alpenpaesse.co/ITALIEN-Gi...o_di_Giau_p371) in the Dolomites in Northern Italy is one of the top passes in my book. Driven it several times. Love it. The view at the top is spectacular too.
To all those doing a European Delivery: consider driving this pass - it's a motoring feast and not as crowded as the notorious (over)hyped Stelvio Pass (Passo dello Stelvio).
I sent the whole group over that pass during the Sella 1.0 (2014) and Sella 3.0 (2016) editions and everyone raved about it for all the right reasons.
