Calidario Terme Etrusche
Bathe in a thousand-year-old thermal spring
In the heart of Venturina Terme, Calidario Terme Etrusche is home to one of Tuscany’s most remarkable natural thermal springs.
At the centre of the experience is the historic Natural Spring, a thermal lake covering more than 3,000 square metres, fed by water that naturally rises from underground at a constant temperature of around 36°C (97°F) throughout the year. This rare geological phenomenon, considered one of the most significant in Europe, has been offering a place of wellbeing and relaxation for centuries.
Surrounded by nature and immersed in warm thermal waters, guests can enjoy a deeply restorative experience in every season.
