We're going to be in the Cinque Terre for a few days this summer (it's our second visit). One on the ideas I'm tossing around is riding the train from our home base in Manarola to Monterosso and taking the coastal ferry/boat all the way to Portovenere. We'd spend the afternoon in Portovenere and then take the boat back to Manarola.
We've hiked the area pretty extensively so i'm wondering if the boat is worth it? Is Portovenere worth it? Is the scenery from the water spectacular or just meh? I'd love to hear of your experience if you've done this trip or some variant of it.
