Getting There -- Approximately 30 daily trains run between Siena and Poggibonsi (one about every half hour, trip time: 25–40 min.), from where more than 30 buses make the 25-minute run to San Gimignano Monday through Saturday; only six buses run on Sunday. Buses stop at Porta San Giovanni; you can easily walk into town from here, but shuttle buses make the run up to Piazza della Cisterna (.75€, buy a ticket from a newsstand or on the bus).
SITA (www.sitabus.it; (tel) 055-47-821) and TRA-IN (www.trainspa.it; (tel) 0577-204-111) codeshare hourly (at least, fewer on Sun) buses for most of the day from both Florence (50 min.) and Siena (45 min.) to Poggibonsi, many of which meet right up with the connection to San Gimignano (a further 20–25 min.). From Siena there are also 10 direct buses (1[bf]1/4 hr.) Monday through Saturday.
Arriving by car, take the Poggibonsi Nord exit off the Florence-Siena highway or the SS2. San Gimignano is 12km (7[bf]1/2 miles) from Poggibonsi.
Visitor Information -- The tourist office is at Piazza Duomo 1 (www.sangimignano.com; (tel) 0577-940-008). It’s open daily March through October from 9am to 1pm and 3 to 7pm, and November through February from 9am to 1pm and 2 to 6pm.
Festivals & Markets -- The citizens dress up in elaborate masks and costumes for a Carnival parade just before Lent. Dentro e Fuori le Mura has, since 1924, brought some lightweight culture to town on the last weekend in July, with open-air opera recitals, classical concerts, and film screenings in the ruins of the Rocca fortress. Thursday and Saturday morning see a bustling market on Piazza del Duomo.
