When to go, how to arrive and how to move through a medieval city built for walking.
Siena is a hill town of brick and stone, its UNESCO-listed centre crowned by the shell-shaped Piazza del Campo. Summers are hot and dry, winters cold, and April–June plus September–October are ideal. The Siena tourism board is the official source for events, including the Palio dates.
Siena has no airport: fly into Florence or Pisa and continue by rail or road. The train from Florence takes about an hour and a half via Empoli, and direct buses also run; the station sits below the old town, with escalators and buses climbing to the centre. Once inside the walls, the city is pedestrian - leave the car at the parking lots at the gates.
