Polichnitos Thermal Springs

The springs are indicated for rheumatism, arthritis, sciatica, myalgia, gynecological conditions, and skin diseases, making them a popular spa-tourism destination. The natural environment combined with the water’s therapeutic properties offers an experience of wellbeing and connection with the power of Lesvos’ earth.
