Istarske Toplice

Istarske Toplice sits in the village of Gradinje, in the canyon carved by the Mirna river about 11 km southwest of Buzet in central Istria. The thermal water, sodium-calcium-chloride-sulfate in composition, emerges at roughly 32–34°C and carries natural sulphur (around 33–38 mg of hydrogen sulphide per kg) along with measurable natural radioactivity, properties long used for anti-inflammatory and rehabilitative treatments. The site's older Italian name, Terme Santo Stefano, and the ruined church of St. Stephen still standing there point to a bathing tradition going back centuries in this part of Istria. Today it operates as a health, rehabilitation and wellness resort offering physical therapy, thermal bathing, mud treatments and inhalation therapy.
