Thérmē is a geothermal spring in Greece whose name — simply the ancient Greek word for 'heat' — is one of the most elemental designations in the thermal bathing lexicon, connecting this site directly to the ancient Greek understanding of geothermal warmth as a gift of the earth and a source of healing. Greece's volcanic and tectonic activity produces numerous thermal springs across the mainland, the Aegean islands, and the northern borderlands, and Thérmē contributes to this extraordinary geothermal heritage. The spring offers naturally warm, mineral-enriched water in the authentic tradition of Greek thermal culture.

Insider tip — Therme on Ikaria island in the Eastern Aegean is one of Greece's most celebrated natural thermal destinations, where warm and mildly radioactive mineral water emerges from granite at 40°C and has been visited since antiquity. Ikaria is recognized as a Blue Zone where inhabitants regularly live past 90, and its springs — noted for their radon content — are part of the island's cultural identity. The waters flow directly into simple stone pools set into the rocky shoreline, allowing bathers to mix warm mineral water with cool Aegean seawater. The village of Therme is the social hub of the island's spa culture, with modest accommodation and tavernas surrounding the spring area.
