Located on the Greek island of Kos in the Dodecanese archipelago, Thermes de Kos is a natural treasure offering an unforgettable experience. The site's thermal waters are characterized by their sulfurous properties, rich in minerals and beneficial for relaxation. Visitors can unwind in a serene atmosphere, surrounded by lush greenery and picturesque views. The historic site has been carefully restored to preserve its original charm.
Insider tip — The thermal springs of Kos Island discharge directly into the shallow Aegean Sea near Agios Fokas beach, where hot sulfurous water mingles with cool seawater to create a natural outdoor thermal experience unique in the Greek islands. The contrast of volcanic warmth against turquoise Mediterranean waters is most vivid in spring and autumn when air temperatures stay mild. The site is open and free to access, and the sulfurous sea-floor vents are visible through the clear water at low tide.
