The tourist information office in Greve is an excellent source for general information about the Chianti wine region and its hilltop towns. In Siena the centrally located tourist office, in Piazza del Campo, has information about Siena and its province. Both offices book hotel rooms for a nominal fee. Offices in smaller towns can also be a good place to check if you need last-minute accommodations.
Tourist bureaus in larger towns are typically open from 8:30 to 1 and 3:30 to 6 or 7; bureaus in villages are generally open from Easter until early November, but usually remain closed on Saturday afternoon and Sunday.
