Kamena Vourla thermal springs are classified by specialists as the most important in Greece and generally in Europe.
The springs were created from the geological transformations of the Maliakos Gulf and of the Kallidromos-Knimis Massif. They became famous due to their rare composition of minerals, salts and radon.
The thermal springs of Kamena Vourla, which gush forth at the foot of Mount Knimis, have varied levels of temperature and radioactivity. There are:
- The radioactive springs
- The hydrogen sulphide-chloride spring
- The ferruginous spring
- The cosmetic spring of Aphrodite
The temperature of the springs is 35o – 36o C and their waters are suitable for many different health problems, such as chronic rheumatisms, kidney, skin and gynecological diseases.
Another well known thermal springs complex of the region, is the one at Thermopylae. There are two main springs, the spring of Leonidas (37 deg. Celsius) and the spring of the Three Hundred (40 deg. Celsius). The thermal baths of Thermopylae are indicated for rheumatic, gynecological and peripheral nervous system conditions.
