Orvieto is one of the most striking, memorable, and enjoyable hill towns in central Italy. Less than 90 minutes from Rome, Orvieto sits majestically high above the valley floor atop a big chunk of "tufo" volcanic stone, overlooking cypress-dotted Umbrian plains.
A visit here will reward you with a delightful, perfectly preserved, and virtually traffic-free world highlighted by a colorful-inside-and-out cathedral and some of Italy's best wine.
