The province is divided into seven historical areas:

The area is a hilly one: in the north is Colline del Chianti; Monte Amiata is the highest point at 1,738 metres (5,702 ft); and in the south is Monte Cetona. To the west are the Colline Metallifere (“Metallic Hills”), whilst the Val di Chiana lies to east.

Historically, the province corresponds to the former Republic of Siena.

The chief occupations are agricultural (wheat, grapes and fruit) and silk culture. The wine known as Chianti is produced here as well as in other parts of Tuscany: the Chianti Colli Senesi, however, is limited to this province.

Apart from the city of Siena the principal towns are Poggibonsi, Colle di Val d'Elsa, Montepulciano, Chiusi, and San Gimignano.
