This spot is often overlooked by people visiting Riomaggiore, but in my opinion is one of the best in town. It's easily reachable as it's on your way to the castle from the San Giovanni Battista church. You'll definitely stumble on it.

I find it to be a great photo spot as well, you got a unique view of Riomaggiore and can see the whole town from here. Such a great spot!
