Oh My Goodness! I LOVE this video! Never heard of this gorge but it is now on my bucket list of drives. Reminds me very much of a motorcycle trip I took years ago (1980!) through the eastern part of what was then Yugoslavia, heading to Sofia in Bulgaria. One minute bright sunlight, the next unlit tunnels blasted through rock. Really hard to see where the road was going. Also where are the roads in your pictures? One could be the Stelvio pass, but I could be wrong. Please do post your route as I am itching to do a European Pass trip!
