Theia, "she who shines far", was the mother of Selene in Etruscan mythology and the brand new spa pools, four outdoor and three indoor, couldn't not be named after her. The pools - over 500 meters squared of tubs - are all connected and filled with water from the Sillene spring. They are located in via della Foresta, behind the Sillene structure which is accessed from Piazza Marconi. Animated by water jets and hydromassage, they are equipped with parasols and sunbeds. There is also a bar-restaurant and wifi connection. Rich in carbon dioxide, calcium carbonate, bicarbonate and sulphates, which give it its typical opaqueness, the waters offer an antiinflammatory action on the muscular, skeletal system and are nourishing for the skin. Children below three years of age are admitted and do not have to pay the entrance fee, however they may not use the pools. Children above three years of age may use the pools along with their parents.
The temperature of the water in the pools is between 33 and 36 degrees, so the outdoor pools may also be used in all seasons. The tub floor and the outdoor areas are furnished with loungers, sunbeds, parasols, tables and chairs. There is also a bar offering hot and cold dishes. There are different entrance formulas. Prices vary from 12 Euros for 4 hours on weekdays. There are also special family offers. Closed on Tuesdays. No reservation for entrance, only for massages.
