A hot spring, thermal spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma or by circulation through faults to hot rock deep in the Earth's crust.
Insider tip — This geothermal groundwater source near Ihtiman in the Sofia Region lies along one of Bulgaria's active tectonic fault lines where heated groundwater from the Rhodope crystalline basement percolates upward at 38°C. The Sofia basin and surrounding Sredna Gora mountain range sit above one of Southeastern Europe's most geothermally active zones, with dozens of natural hot springs distributed across the region. This particular source feeds local agricultural and domestic use as well as occasional balneotherapy. The landscape of rolling hills and oak woodland around Ihtiman gives a rustic, undeveloped character to the site.
