Thermal Baths & Hot Springs

Viterbo sits atop a significant geothermal field, resulting in a high concentration of sulfurous thermal springs used since Etruscan and Roman times. This selection includes both developed spa resorts and rustic, association-managed sites like Bagnaccio and Masse di San Sisto. These volcanic waters, often reaching temperatures between 40°C and 58°C, are characterized by high mineral content and therapeutic properties. Many of these locations feature outdoor pools set within the Lazio countryside, maintaining a tradition of public bathing that spans centuries.
