Tunnels
I had previously thought the Italians were the experts on tunnels – why go over when you can go through. They know nothing compared to the Swiss! As we left Italy (Venice via Lake Como), on our way to Bern, we passed thru the longest tunnel in the world!
The Gotthard Tunnel is 35 miles long and you just don’t want to think about it while you are in it. On the Swiss side, as you exited any tunnel, you would be in a different world than the one you entered. And Switzerland is drop-dead gorgeous!
