If you stay in Orvieto for three days, you can spend the first two exploring the city's best-known sights and set aside the third for an enjoyable trip to Civita di Bagnoregio and Bolsena.
This itinerary is designed for unhurried travel: the first two days are mainly on foot, while a car is recommended for the trip outside Orvieto. The stops are flexible and can be rearranged depending on the weather.
It is an ideal plan for anyone who chooses Orvieto as a base for exploring Umbria and Upper Lazio: explore the historic centre at a relaxed pace over the first two days, then visit two different but easily combined destinations on the third.
