We visited the Cinque-Terre National Park twice during the trip, both times staying in the town of Vernazza and walking or taking the train to the other 4 nearby towns of Monterosso, Corniglia, Manarola, and Riomaggiore.

This is the view of Manarola as you walk to it from Corniglia... digitally enhanced by Bernadette.

The first link is to a 1-1/2 minute video of Manarola.

And the second link is a 4 minute walking tour of Cinque Terre. Everywhere we went, we walked and walked, and saw others walking.

The paths from town to town in Cinque Terre are highly developed, and officially classified as Easy, Slight, Average, or Tough. We didn't do take any of the Tough ones.
