Concierge.com's insider take:
With its ripple of bright houses on a rocky promontory and its main piazza chock-full of fishing boats above a pocket-sized harbor, it's easy to see why many visitors consider Vernazza the archetypal Cinque Terre village. It's also easy to understand why it's best avoided on Sundays in July and August. Like most of the Cinque Terre, Vernazza was founded in the early Middle Ages. When the Cinque Terre fell under the influence of Genoa toward the end of the 13th century, it was Vernazza that was considered the real prize, as it was the only one of the five villages to have a true harbor (its strategic importance was reflected in the fact that Vernazza had its own seat in the Genoese parliament). From the train stationcentrally located, for onceVia Roma snakes down to harbor-front Piazza Marconi, with its cluster of tempting bars and restaurants, framed by the bell tower of Santa Margherita di Antiochia and the tall keep of the Doria Castle.
