On your final day, visit the historic city of Siena, famous for its medieval architecture and the Palio horse race. Explore the narrow streets of the city center and marvel at the magnificent Siena Cathedral and Piazza del Campo. Afterward, head to the charming hilltop town of San Gimignano, known for its well-preserved medieval towers. Wander through the town's narrow alleys, visit the local artisan shops, and sample the famous saffron-flavored gelato. As you bid farewell to Tuscany, take in the breathtaking views of the countryside one last time before heading back home.
