The 4 Natural Pools at the Vulci Spa are different in colour, temperature and properties, each one acts on different aspects of the body and mind, but all are a cure-all for physical and spiritual wellbeing. Natural hyperthermal water (up to 42°C), naturally carbonated, rich in mineral salts: bicarbonate, sulphate, calcium, magnesium, fluorinated, ferruginous, acidic and microbiologically pure. Mud balneotherapy in the treatment of arthritic-rheumatic diseases and balneotherapy for dermatological diseases and phlebo-pathologies. It is an unparalleled experience to enjoy the vegetation of the Maremma countryside while immersed in the warm spa, under the blue sky and the shade of the olive trees.
