Cinque Terre is a string of centuries-old seaside villages on the rugged Italian Riviera coastline. In each of the 5 towns, colorful houses and vineyards cling to steep terraces, harbors are filled with fishing boats and trattorias turn out seafood specialties along with the Liguria region’s famous sauce, pesto. The Sentiero Azzurro cliffside hiking trail links the villages and offers sweeping sea vistas.
