Select a 1- or 2-hour private, guided tour of Siena to get an insider's perspective on Siena's rich history and culture. Multiple departure times fit your vacation schedule. At the Piazza del Campo, learn about the famous Palio horse race and the square's architecture that dates back to the Middle Ages. On the 2-hour tour, visit the Duomo, a beautiful cathedral, or the Civic Museum. Ideal for small groups, the per-person price of this private tour decreases the more participants there are.
