Cinque Terre refers to five towns in northern Italy, right on the Mediterranean Sea, what might be called the "Italian Riviera." We were there a couple of weeks ago and the weather was gorgeous. There are trails connecting the five towns, but one can also travel between the towns by rail or by boat. (By car, maybe, but that's much more difficult, and there are no cars allowed in the towns themselves, aside from delivery vehicles.)
I walked from Monterossa to Vernazza one afternoon. It took less than two hours, but there was plenty of vertical involved. I was surprised by the toll booth. It cost me eight Euros! I believe there's a reduced-rate ticket if one wants to walk more of it. The next morning my sister and I left Vernazza early and hiked partway toward Corniglia and back. The ticked booth hadn't opened yet so we got to walk that bit "for free."
Goes to show what a great deal we all get from the AT. I don't begrudge them the eight Euros. Every inch of this trail was heavily engineered. Without an army of volunteers (like we have on the AT) someone's got to pay.
