Terme di Sassetta, in Tuscany, taps sulfurous water at 40°C, pH 6.5. This Tuscan facility offers indoor pools, massages, and a sauna in a rural setting.
Insider tip — Terme di Sassetta is a small thermal spa in the Colline Metallifere zone of coastal Tuscany at approximately 43.1°N, 10.7°E, an area geologically active with geothermal energy exploited at nearby Larderello. The sulfurous waters emerge from the same volcanic-hydrothermal system responsible for Italy's most productive geothermal field. Surrounded by Mediterranean maquis and chestnut forests, the site offers a quiet alternative to the more crowded Tuscan thermal resorts. The facility combines classic Italian terme tradition with the landscape appeal of the Etruscan Coast hinterland.
