The Aquarius Élményfürdő and Parkfürdő complex in Nyíregyháza is one of eastern Hungary’s largest and most developed spa destinations, located in the Sóstógyógyfürdő resort area.
It combines medicinal thermal bathing with a full-scale aquapark, featuring thermal pools, swimming pools, adventure areas, and extensive children’s facilities. The Aquarius aquapark includes slides, wave pools, and a lazy river, making it a major draw for families.
The wellness section offers saunas, steam baths, massages, and physiotherapy services, while the surrounding Sóstó park environment adds outdoor recreation value.
Due to its scale, diversity of services, and strong regional pull, it functions as a high-tier destination spa and one of the main tourism anchors of northeastern Hungary.
