Shahre Aftab Hydrotherapy (Sarein)

Shahre Aftab ('City of Sun') Hydrotherapy in Sarein, Ardabil Province, is a large thermal spa complex drawing on the oligomineral geothermal water of the Sabalan volcanic system to offer an extensive pool and wellness facility in Iran's premier thermal resort town. The name 'City of Sun' reflects Sarein's growing aspiration to position itself as a year-round thermal tourism destination that combines the volcanic energy of Sabalan with the appeal of northern Iran's diverse seasons — mild summers in the Ardabil highlands and the proximity of the Caspian coast's subtropical microclimate make the region a multi-season destination. Shahre Aftab's large-scale facilities, designed to accommodate the volume of Iranian domestic tourists who make Sarein one of the country's most visited internal tourism destinations, represent the commercial ambition of a spa town capitalising on one of the Middle East's richest geothermal resources.
