Terme Olimia

Terme Olimia sits east of Podčetrtek in eastern Styria, drawing its water from wells around 500–520 meters deep that reach temperatures reported up to the low 40s°C at the wellhead before blending for pool use. Long known locally, the springs were developed into a formal spa opened on 9 September 1966 under the name Atomske Toplice ('Atomic Springs') — a period name reflecting the era's enthusiasm for the weak natural radioactivity of the calcium-magnesium bicarbonate water, used in the resort's first wooden therapeutic pool. The facility has since grown into one of Slovenia's largest spa complexes, now trading as Terme Olimia, with the adjoining Aqualuna water park drawing on the same underlying thermal resource.
