Sarein Hot Springs in Ardabil province, northwestern Iran, is the country's premier thermal resort town, where over 40 bathhouses cluster around volcanic springs from the Sabalan stratovolcano — the third-highest peak in Iran at 4,811 meters — producing some of Iran's hottest and most mineral-rich sulfurous waters. The proximity to the UNESCO World Heritage Ardabil Shrine — the Safavid dynasty's spiritual foundation and one of Persia's most magnificent architectural complexes — adds profound cultural depth to the thermal experience. Sarein receives millions of Iranian domestic visitors annually, drawn by the sulfurous waters and the lively resort atmosphere of a destination that functions as the thermal equivalent of a Persian Karlovy Vary.

Insider tip — Sarein lies 25 km from the dormant volcano Sabalan and is Iran's most visited hot-spring destination, with dozens of private and public sulfurous pools fed by springs that emerge at up to 70°C before being cooled to bathing temperature. The volcanic highland setting at 1700 m means air temperatures are refreshing even in summer, and the fog rising from the pools at dawn creates an otherworldly atmosphere. The local Ardabili bread, baked in clay ovens nearby, makes an ideal post-bath breakfast.
