The Euganean Thermal Basin around Abano and Montegrotto Terme is Europe's largest spa cluster, with over 100 hotels and thermal establishments tapping deep aquifers. The water emerges at 87°C, highly mineralised and slightly radioactive, and cools to therapeutic bathing temperature before use. The region is world-renowned for fango (volcanic mud) therapy, where the mineral-saturated mud is matured in the thermal water for several months before application.

The Euganean thermal basin has been exploited since Roman times, when Fons Aponi (Abano Terme) was a celebrated resort visited by emperors and senators. The region's thermal heritage is documented in works by Livy, Claudian, and Cassiodorus. The volcanic Euganean Hills are a Regional Natural Park, and the springs' origin in deep volcanic geology makes them a living geoscience heritage.
The Euganean tradition of fango therapy — therapeutic volcanic mud matured in thermal water — is the most medically embedded spa practice in Europe. Italian medical spas (terme mediche) operate under national health regulations, and fango therapy at Abano and Montegrotto has been prescribed by Italian physicians for rheumatological conditions for over a century, creating a unique fusion of medical institution and spa culture.
The Euganean thermal basin's 87°C deep aquifer requires careful management as a finite geothermal resource. The Regional Authority of Veneto regulates extraction volumes, establishes spring capping protocols, and monitors aquifer pressure to prevent subsidence — a historical problem in the 20th century. The Colli Euganei Regional Park protects the recharge zone and limits development that could compromise the deep aquifer.
