A sodium-calcium chloride spring rising at a notably hot 65.8 °C — among the hotter natural sources documented in the region. The water is moderately mineralized (around 2,800 mg/kg evaporation residue) with a salty, heat-retaining character, weakly alkaline and gentle on the skin, and leaves a faint mineral film on emerging.
