Discovered in 1889, the Thermal Waters of Sirmione have precious and unique properties. They contain sulphur, sodium chloride, bromide and iodide, zinc, manganese and selenium. The spring is generated on Mount Baldo, at 800 metres a.s.l. and then penetrates 2,500 metres below sea level, where it is enriched with minerals and increases its temperature before re-emerging in the lake. It takes 20 years to complete the cycle and become a thermal spring; during this process it remains bacteria free. It is famous throughout the world because it treats respiratory, rheumatic and vascular disorders, rhinogenic deafness, skin and gynaecological ailments. In other words: sinus conditions, bronchitis, ear infections, psoriasis, arthrosis and motor rehabilitation.
