Grosseto is the capital of the Maremma, the wild southern stretch of Tuscany that most tourists skip in favour of Florence, Siena, and the Chianti hills. The city itself is a modest provincial centre ringed by well-preserved Medici walls, but the real draw is the surrounding countryside — rolling farmland, cork-oak forests, thermal springs, and a coastline that includes some of Tuscany's best beaches.
The Maremma is famous for its agriturismo culture. Organic farming is popular, and the food here is excellent: sun-ripened tomatoes, artichokes, wild mushrooms, olive oil, and above all wild boar, which appears on almost every menu. The Etruscan past of the region is visible too — the Maremma Archaeological Museum in the old centre holds some of the finest Etruscan finds in Tuscany. The Maremma Regional Park to the south protects the wildest stretch of the Tuscan coast, and the natural hot springs at Terme di Saturnia are an hour's drive away.
The most attractive coastal town in the province is Castiglione della Pescaia, a small fishing village dominated by a medieval castle, with rocky coves, pine-backed beaches, and a working harbour. It is an easy day trip from Grosseto or a destination in its own right.
