Set on three hills and reputedly the best preserved, walled city in the Tuscany region, the pedestrianised medieval centre of Siena is well worth a few days exploration on foot. Apart from many fascinating museums and the ornate decoration of major churches including the Duomo atop the city's highest point, more attractions lie within its ancient portals and old town walls. There is a surprisely vibrant nightlife in this university town with many cafes and bars open till late. And Siena is home of the Palio in July and August so early booking is essential. At this very popular time, guests come from all over the world to celebrate the lifestyle of the Sienese and their passion for a crazy festival of horse racing around the Piazza del Campo.
