Beli Iskar Thermal

Beli Iskar Thermal is a natural mineral spring and bathing destination near the Beli Iskar River on the northern slopes of the Rila Mountains, the highest mountain range in Bulgaria and the broader Balkan Peninsula, where the ancient granite and metamorphic geology of the Rila Massif produces bicarbonate mineral waters of therapeutic value. The springs are located within the sphere of influence of the Rila National Park — home to extraordinary alpine landscapes, glacial lakes, and the revered Rila Monastery, Bulgaria's most important spiritual and cultural monument — giving the thermal bathing experience an unusually sublime mountain setting. The waters are valued for their gentle mineralogy and comfortable temperature, offering a restorative bathing experience complemented by the clean mountain air and the exceptional natural environment of the Rila highland. Beli Iskar Thermal is a hidden gem of Bulgarian thermal heritage, combining mineral water wellness with one of the Balkans' most magnificent mountain landscapes, in the shadow of peaks that Bulgarians have revered as a spiritual center for over a thousand years.
