A stone’s throw from Radicofani, Fonteverde, in San Casciano Bagni, is one of Tuscany’s most exclusive thermal baths with a modern swimming pool and a leading wellness centre. On the other side of the Val d’Orcia, how can one forget the charming Bagno Vignoni, a favourite spot of Caterina da Siena and Lorenzo de’ Medici? In the province of Siena, it is also worth mentioning the Terme di Rapolano and Petriolo, the latter being, in its time, such a favourite of Pope Pius II that he had the first buildings round the water built there. The strange thing about this place is that you can go from the warmth of the pools to the cold of the Farma and vice versa. The Sarteano baths, with their cold water, are equally beautiful and are home to a circular waterfall, the work of a famous Japanese designer. After bathing, you can always set out to admire the gorgeous countryside and, above all, the splendid fresco by Beccafumi in the San Martino church.
