I live on the coast and the water and appreciate the sea and views and beach. It was a different landscape than my Fl and I think it is well worth a trip. The op didn't ask us that though. So sorry I gave my positive opinion.

Do ferry if nice weather but train is quick and great back up. Have a great trip.

Hiking, thus using your feet, is the preferred way to visit the Cinque Terre villages

"Hiking, thus using your feet, is the preferred way to visit the Cinque Terre villages" -- Indeed! But fortunately, hiking BETWEEN the villages is not a requirement. :-)
