The January air may be chilly but at the hot water spas in the Viterbo area, there are dozens of happy people soaking in the outdoor pools enjoying the sun along with revitalizing heat from the sulphuric waters and vapors that flow from the source at 58°C.
Several countryside hot baths are scattered along a 12-kilometre fault line stretching between Vetralla and Viterbo with the favorite of local expats and Romans being Le Masse di San Sisto, located at the 77th kilometer of the Via Cassia.
