In Tuscany, the towers and castles of San Gimignano dominate sun-drenched hillsides, while the humbler paths walked by St. Francis wind through Assisi. Visit them and the ancient Etruscan frescoes in Orvieto. On the Italian Riviera, follow the rugged coastline of Cinque Terre, dine on fish freshly caught in the cove of Manarola, stroll the beaches of Corniglia, and relax in the resort town of Monterosso.
