Hajdúszoboszló is Hungary's most popular thermal resort town and one of the largest spa complexes in Central Europe. The thermal spring was discovered in 1925 during oil exploration — the water that gushed up at 73°C turned out to have extraordinary medicinal properties. Today the Hungarospa complex covers 30 hectares and includes over 30 pools: indoor and outdoor thermal pools, swimming pools, adventure pools, water slides, a wave pool, solaria, medical treatment departments, and full wellness facilities. The iodine-bromine-sodium chloride water is world-renowned for treating locomotor, degenerative, and inflammatory conditions, as well as gynaecological disorders. Hungarospa operates as both a medical spa and a leisure complex, accommodating over a million visitors per year.
