Embros Thermes, Hot spring on the southeast coast of Kos, Greece

Embros Thermes is a natural hot spring on the island of Kos that releases mineral-rich water into a stone basin near the shore. The heated water continuously flows toward the sea, creating a unique bathing experience along the coast.

The spring emerges from a fissure in the rock a few metres off the southeast coast of Kos, about 12 to 13 km from Kos Town at the end of the coastal road. Its water reaches 40 to 50 °C and carries a sulphur smell. A channel feeds a 25 m² basin built of rocks, which connects to the Aegean Sea.

Bathers at Embros Thermes stand or wade in the rock-enclosed pool, which holds water from a 49 °C sulphur-smelling spring. The water is said to help skin, eye, respiratory and muscle conditions, rheumatism and arthritis. Gas bubbles rise from the seabed nearby.

The site is located roughly 12 kilometers from Kos Town and requires about a 15-minute walk from the free parking area. Wear sturdy shoes and bring water, as the path crosses rocky and uneven ground.

The spring water emerges from the seabed a few metres offshore at 40 to 50 °C and is led through a man-made channel into the rock basin, which connects directly to the Aegean Sea. Bubbles of gas also rise from the sea floor around the spring.
