Practical help for health and mental well-being.


Ischia belongs to the volcanic system of the Phlegraean Fields, a crater where the signs are volcanism are very much present with fumaroles, the solfatara of Pozzuoli, the thermal baths of Agnano in Naples, etc.
The island also has a secondary volcanic activity, which is manifested by minor phenomena, such as solfataras (emissions of superheated steam mixed with sulphur), fumaroles and mofette (hot emissions of steam and carbon dioxide) and, especially, thermal waters, rich in beneficial substances.

Water purity

The water for curative and bathing purposes that we use in the pools, natural sauna and for inhalations are taken directly from thermal-mineral springs: they're regularly subjected to rigorous quality checks to ensure their chemical, physical and bacteriological purity.
Our water treatment philosophy

Properties of the water

Our thermal and hyperthermal (over 40°) springs of volcanic origin belong to the saline-bromine-iodine and saline-alkaline-sulphate group, with small quantities of various trace elements, such as calcium, magnesium, lithium, etc.
The richness and variety of salt concentration, as well as the temperature increases in the pools from 28° C to 40°C, allow differentiated baths according to individual needs.
