We visited the Cinque Terre, which is about an hour from where we were staying in Viano. The Cinque Terre are five mountain towns nestled along the coast of the Mediterranean. A ferry shuttles you from one town to the next. We didn't get a chance to see all of the towns, but it was a really incredible experience.
There is a cliff walk between the towns Riomaggiore and Manarola. It had some really beautiful views of the sea and some great graffiti.
