Further north on the ferry from Manarola to Monterosso we passed Vernazza. Vernazza is called out in Rick Steves' book on the Cinque Terre as his favorite village. Obviously lots of people read Rick Steves. When the ferry got to the harbor of Vernazza the dock was absolutely packed as were the streets beyond it. We stayed on the ferry.
