Best for travelers looking for a natural spa-style sea experience.
The Therma Beach Hot Springs, located on the easternmost tip of Kos, owes its origin to volcanic activity and the shifting of tectonic plates millions of years ago. The name ‘Therma’ comes from the Greek word for warm baths, highlighting the natural hot springs that define this unique coastal spot. Visitors can enjoy waters ranging from 30°C to 50°C, depending on the pool, set amidst a striking landscape of black pebbles, rocks, and steep cliffs. The mineral-rich waters contain calcium, magnesium, potassium, sulfur, and sodium, and are traditionally valued for their therapeutic properties. Many come to soothe skin conditions, arthritis, and rheumatic ailments, benefiting from the natural composition of the springs. The hot pools are naturally enclosed by surrounding rocks, which help retain warmth while allowing sea water to mix in for a comfortable temperature. Access to Therma Beach is possible by bus or private transport. The descent to the shore requires care, as the path is rocky and uneven, but the reward is a memorable bathing experience. A local favorite is visiting after dark, when the absence of artificial light reveals a sky filled with stars, adding a magical atmosphere to the thermal soak. Seasonal conditions can influence water temperature and wind exposure, so a light jacket may be useful when walking along the cliffs.
