Natural caves

At Bagni di Lucca spa you can find two natural steam caves where the temperature reaches the +40°C.

Healing waters

The water in the caves at Bagni di Lucca are rich of sulphur, bicarbonate and calcium. Whoever suffers from rheumatic diseases can benefit of our spa treatments, which are also great for reducing stress. A folktale says that the high temperatures of the water are caused by an existing volcano below Bagni Caldi and the nearby Ponte a Serraglio.

Grotta Grande

Grotta Grande is the main cave, fueled by the source “il Doccione”, a thermal cold shower  is also provided to help you balance your body temperature after the steambath. To follow, you will be wrapped in a warm towel and offered a natural infusion made with our thermal water.

Grotta Paolina

The smallest and most fascinating cave. Named after one of its most famous guests of all the time, Napoleon’s sister. Made by two cavities fueled by the source “il Fontino”, this cave peculiarity is that the temperature is not perceived the same in the whole body, as it gets colder on the legs and feet. To follow, you will be wrapped in a warm towel and offered a natural infusion made with our thermal water.
