Day trip from Florence to Siena: how to get there and what to do

Three ways work: regional train, direct bus, or car. The train is the simplest because it leaves from Florence's main station in the city centre and drops you about a kilometre from Siena's historic core. The bus is often a little faster and drops you closer to the walls, but seats can sell out on weekends and holidays. Driving gives you flexibility for Chianti, but you cannot drive into Siena's centre, and parking sits outside the walls.

Regional trains run roughly hourly through the day; some services need a change at Empoli, so check the departure board rather than assuming a direct train. Buses run frequently from Florence's bus terminal near the main station. Tickets for both are cheap enough that a day return costs less than a sit-down lunch in Florence.

If you drive, take the motorway south and use the park-and-ride lots on the edge of Siena, then walk or take the escalators up into the centre. Do not attempt to reach the piazza by car; the historic centre is restricted and cameras enforce it.

Leave Florence between 8am and 9am so you reach Siena before the middle of the day. Walk from the station or bus stop into the centre and start at Piazza del Campo, the sloping shell-shaped square where the Palio horse race is run twice each summer. Climb the tall tower beside it if the queue is short; the view over the red rooftops is the reason many people come.

Then move to the Duomo, Siena's black-and-white striped cathedral, which holds frescoes, a marble floor and a library of illuminated choir books. Book a timed entry in high season or expect a queue. If you have time, the museum next door, Santa Maria della Scala, fills another hour or two with frescoes and archaeological finds.

Eat lunch away from the piazza; a few streets back the same dishes cost less. After lunch, walk the contrade streets, look into the medieval fountains, and finish with an ice cream or a coffee before catching a late-afternoon train or bus back. Aim to be back in Florence by early evening.

A day trip by public transport is one of the cheaper outings from Florence. The return fare is modest, and the main variable is how much you spend on the Duomo complex and food. Prices below are 2026 estimates; check current fares and ticket prices before you go, since both change.

If you take an organised tour, the price usually includes transport and sometimes a guide or a winery stop, which can be better value than it looks once you add up separate tickets. Independent travel stays cheaper if you skip the paid interiors.

For most visitors, no. Siena's core is compact and five to six hours covers the square, the cathedral and a good walk. The case for staying is the evening: once the day coaches leave, Piazza del Campo fills with locals and the streets go quiet, which is a different city from the one you see at noon.

Stay if you want to pair Siena with the surrounding countryside, or if you are travelling on to the Val d'Orcia or Chianti by car. Otherwise, keep your Florence base and use the saved night there — Florence itself rewards a third night more than Siena does a second.
