Insider tip — Thermes Polichnitos on the island of Lesbos in the Eastern Aegean are among the hottest natural thermal springs in Europe, with source temperatures exceeding 87 degrees before cooling to bathing temperature in the indoor pools. The sulfurous sodium-chloride waters emerge from volcanic geology on this geologically active island, just 8 kilometers from the Turkish coast. Lesbos is also renowned for its petrified forest — ancient trees turned to stone by volcanic eruption — giving the island a dramatic geological character that extends to its thermal endowment. The outdoor bathing pool set amid olive groves with views toward Turkey is one of the Aegean's most atmospheric bathing spots.
