Among the most examined in Italy, Ischia thermal waters come from springs of volcanic origin - being numerous on the island. During their underground way they mineralize and get warm thus absorbing precious healing substances. The Solemar's Spa uses the waters of the Ischia hydro thermal field whose chemical-physical and biological characteristics (chloride sodium, sulphate bicarbonate hypertonic as well as hyper thermal waters) make them highly effective means against numerous health conditions.
