Budapest is well known for its numerous medicinal baths, which constitute one of its main tourist attractions. Some of the thermal springs were already being used as early as the 2nd century by the Romans.
A number of the medicinal baths built along the bank of the Danube by the Turks - the Király, Rudas, Császár and Rác Baths - are still being used today. Budapest was officially declared an International Spa in 1934.
The thermal springs, the temperatures of which vary between 21°C and 78°C, yield up to 70 mega-litres of water per day. The dissolved salts and minerals present in these waters, derived from 118 different sources (either natural springs or bores), render them suitable for treating a diversity of illnesses – ranging from circulatory problems to joint and muscle damage, and menstrual pain.
Besides bathing, most of the baths in Budapest provide facilities for therapeutic massages, physiotherapy exercises and mud-pack treatments.
In the vicinity of the baths, one can find wells and arrays of drinking-water fountains, providing spring-water rich in minerals.
