Where to go in Tuscany in September
Florence
Florence in September means afternoons of 81°F (27°C), pleasant for the Boboli Gardens, one of the 12 Medici villas on the UNESCO list. Palazzo Pitti houses five museums, so it fills a rainy day.
Siena
Siena has been a UNESCO World Heritage Site since 1995. The Palazzo Pubblico holds the Allegory of Good and Bad Government and the Hall of Nine, both indoors and good for a showery day. The Museo Civico offers a free audioguide app in English.
San Gimignano
San Gimignano has been on the UNESCO World Heritage List since 1990. It has three civic museums: the Town Hall with the Picture Gallery and Great Tower, the Church of San Lorenzo in Ponte, and the Complesso Museale di Santa Chiara.
Lucca
Lucca packs its sights into one town: the Walls, the Cathedral of San Martino, the Guinigi Tower, the Torre delle Ore, Piazza Anfiteatro and the Botanical Garden. September’s mild afternoons suit a walk along the Walls.
Val d’Orcia
Its landscape has churches and palaces among the fields. A car makes it easy to link them in a day.
What to do in Tuscany in September
The Maremma Park walk to San Rabano
The Maremma Regional Park is on the coast, and you can explore it on foot, by bike or on horseback. The walking route to San Rabano covers 6 miles (9.6 km) and takes 5 hours.
With about 12 and a half hours of daylight in mid-September, start in the morning. Bring water, since the walk leaves little room for a late start.
Day walks: Via dei Corbezzoli and Via degli Dei
The Via dei Corbezzoli in Cennina covers 8 miles (13 km) and takes 4 and a half hours. The Via degli Dei for Beginners takes two days and covers 17 miles (27 km).
September afternoons at 81°F (27°C) are comfortable for walking. Choose a day without rain, since six days of the month will have it.
the Valdambra Events Program in Bucine
The Valdambra events program runs from April 25 to November 30 in Bucine, so it is still on in September.
Check the program in Bucine before going, since the Valdambra events program 2026 runs from April 25 to November 30 and the Festival of the Regions takes place May 16 and 17.
The markets of Montecatini Terme
Montecatini Terme holds its weekly market on Thursdays at Piazzale Granduca Leopoldo. The Mercato della Terra and the Mercato degli agricoltori are at the Mercato Coperto, Via Mazzini 57.
A daily market, Grocco – La Salute, runs on Viale P. Grocco and Via della Salute. A morning at the covered market also works well on a rainy day.
Is Tuscany busy in September?
In August most people crowd the coasts and Florence empties. The Antica Fiera di Signa, with the Incendio della Torre, draws great participation at the end of August. September follows with cooler weather: Florence drops from 90°F (32°C) in August to 81°F (27°C).
Rental stock in the countryside is varied. It includes Agriturismo La Campana in Asciano, Tenuta Ricrio with private-pool farmhouses of at least 4 rooms and 8 beds, and Il Moreto, a farmhouse with up to 15 beds. Large houses suit groups, so book them ahead.
The stay tax can be up to 5 euros per night. The cap on nights varies by town: three consecutive nights in Lucca, the first 5 days in Casole d’Elsa, 7 nights in Greve in Chianti and 10 consecutive nights in Sesto Fiorentino.
What to pack for Tuscany in September
September calls for summer clothes by day and one warm layer for the evening, plus something for the rain.
- A light sweater or jacket: nights fall to 59°F (15°C) in Florence and 58°F (14°C) in Siena.
- A compact rain jacket: Florence has six rainy days in September.
- Walking shoes: the San Rabano walk covers 6 miles (9.6 km) in 5 hours.
- A sun hat: afternoons reach 81°F (27°C).
- A swimsuit and snorkel gear if you plan to snorkel in the protected seabeds of the coastal parks.
What to know before visiting Tuscany in September
Palazzo Pitti houses five museums, and the Villa medicea della Petraia has been a UNESCO site since 2013. The Fondazione Salvatore Romano is in the Cenacolo di Santo Spirito, and the Bacci Chapel is in the Basilica of San Francesco in Arezzo. Check opening hours before you go.
Add the stay tax, up to 5 euros per night, to your budget.
Is September a good time to visit Tuscany?
Yes, especially for travelers who want walking, towns and countryside at comfortable temperatures.
August is hotter, at 90°F (32°C), with four rainy days in Florence. Shifting four weeks either way trades heat for rain.
If you want to hike, September gives afternoons of 77 to 81°F (25 to 27°C). If you want museums, Siena and San Gimignano have enough indoors for the six rainy days. If you want the water, the coastal parks offer snorkeling and canoeing.
