Siena and San Gimignano are two of Tuscany's most celebrated medieval towns, located 75 km and 55 km south of Florence respectively, and frequently combined into a single rewarding day trip through the rolling Chianti landscape of central Italy.
Neither town is efficiently served by direct train from Florence. The standard approach is the Sita Autolinee bus from Florence's Busitalia terminal at Via Santa Caterina da Siena (adjacent to Santa Maria Novella station). Direct buses to Siena depart frequently and take 75–90 minutes; tickets cost around €8. For San Gimignano, change in Poggibonsi (bus connection, 25 additional minutes). Driving via the SS222 Chiantigiana road adds significant scenic value — Chianti vineyards and cypress-lined farm tracks line the route — and allows flexibility between the two towns.
A suggested itinerary: depart Florence by 08:00 to reach San Gimignano by 10:00, before tour coaches arrive. The town's 14 surviving medieval towers — once there were 72, a symbol of civic rivalry — are visible from the surrounding fields. Inside the walls, the Collegiata di Santa Maria Assunta (Duomo) contains remarkable 14th-century fresco cycles by Ghirlandaio and Barna da Siena. The Piazza della Cisterna, with its 13th-century stone well, is the social heart of the town. Two hours is sufficient for San Gimignano's compact historic centre.
From San Gimignano, drive or take a connecting bus to Siena (30–40 minutes). Arrive for lunch at a trattoria on the Piazza il Campo or in the side streets of the Terzo di San Martino. Siena's UNESCO-listed historic centre rewards at least three hours of exploration. The Piazza del Campo — a sloping fan-shaped brick square — is one of Europe's most theatrical civic spaces. The Gothic Siena Cathedral (Duomo) features a striped black-and-white marble facade, an elaborate pulpit by Nicola Pisano, and the Piccolomini Library with Renaissance frescoes. The Museo Civico inside the Palazzo Pubblico houses Ambrogio Lorenzetti's Allegory of Good and Bad Government, a 14th-century secular fresco cycle of extraordinary scope.
Return buses to Florence depart regularly from Siena's Piazza Gramsci terminal until around 21:00.

Tips for visiting
- The Sita bus from Florence's Busitalia terminal is cheaper and often faster than driving through traffic; book online or arrive 20 minutes early for a seat.
- Visit San Gimignano first in the morning — by midday the town is heavily congested with tour groups; Siena is larger and absorbs crowds better.
- Siena's Cathedral requires a separate ticket (around €8) from the main Piazza del Campo entry; purchase at the OPA ticket office near the Baptistery.
- Parking in Siena is easiest at the Fortezza Medicea or the Campo car parks on the periphery; the historic centre is a ZTL restricted zone for non-residents.
- San Gimignano gelato at Gelateria Dondoli on Piazza della Cisterna has won multiple awards — the queue is worth it.
- Most shops and smaller museums in both towns close between 13:00 and 15:00 for the afternoon break; plan accordingly.
When to visit
April to June and September to October offer the best conditions — mild temperatures, blooming countryside, and smaller crowds than midsummer. Avoid Siena on Palio race weekends (2 July and 16 August) unless specifically attending the race. Winter weekdays offer empty streets and full museum access at reduced prices.
Accessibility
San Gimignano's medieval street plan includes steep cobblestone lanes that are difficult for wheelchair users; the main Piazza della Cisterna has a relatively flat centre. Siena's Piazza del Campo is sloped brick and uneven underfoot; the Cathedral has a ramped side entrance. Visitors with significant mobility limitations will find both towns partially navigable but challenging overall.
Frequently asked questions
Is it possible to see both Siena and San Gimignano by public transport from Florence?
Yes, though it requires careful timing. Buses run from Florence to San Gimignano (with a change at Poggibonsi) and from Poggibonsi onward to Siena. The return bus from Siena to Florence is direct. The journey is feasible but tighter than driving; an early start is recommended.
How long should be spent in each town?
San Gimignano's historic centre warrants two hours; the towers, Duomo, and main piazza can all be seen in that time. Siena deserves at least three hours — the Cathedral, Piazza del Campo, and Museo Civico alone take most of an afternoon. Five to six hours total on the ground is realistic.
Is the Palio horse race relevant for day-trip planning?
The Palio takes place twice a year — on 2 July and 16 August — and draws enormous crowds to Siena. Visiting on Palio weekend requires booking months ahead; accommodation fills entirely. Non-Palio visits are far more relaxed and allow unrestricted access to the Piazza del Campo.
Are Siena and San Gimignano accessible for visitors with mobility impairments?
Both towns present challenges. San Gimignano has steep cobblestone streets within the walls. Siena's Piazza del Campo slopes at a gradient, and many lanes leading to the Cathedral are stepped. The Cathedral itself has a step-free entrance via a ramp; the Museo Civico is accessible by lift.
What is the Chianti wine region connection on this route?
The SS222 road between Florence and Siena passes through the heart of the Chianti Classico DOCG wine zone. Several estate wineries (cantina) offer drop-in tastings; Castello di Brolio and Antinori nel Chianti Classico are among the most accessible for visitors with a car.
