Plot: Exploring Italy's most remote and romantic stretch of Riviera, we visit five tiny port towns: dramatic Vernazza, surrounded by vineyards; reclusive Corniglia, high on its bluff; pastel Manarola; hardscrabble Riomaggiore; and the pint-sized resort of Monterosso. Fishing for anchovies, sipping wine out of rustic barrels, and savoring twinkling Mediterranean vistas, we enjoy the ultimate Riviera adventure
