About Parque Termal Federacion
Parque Termal Federacion, Argentina is a paid public thermal park in the city of Federacion, Entre Rios province, on Avenida Entre Rios at the edge of Lago Salto Grande. The 9-hectare forested park is the first thermal park in Argentine Mesopotamia, opened in 1995. Its water is drawn from the Guarani Aquifer at 1,268 metres depth, emerging at a constant temperature of 42 degrees Celsius with a flow of 450,000 litres per hour.
The water is fresh, potable, and classified as hyperthermal: chlorinated-bicarbonated-sodium, mildly alkaline, and low in mineralisation. The park is divided into zones: a passive area with pools at 37 to 40 degrees Celsius, a covered pool at 41 degrees Celsius with hydrojets, a recreational semi-Olympic pool, shallow children's pools, and a therapeutic spa area with massage and hydrotherapy. An adjacent water park with slides up to 20 metres, a large wave pool, and a nautical plaza is included in the standard entry ticket. For visitors exploring aguas termales in Argentina along the Entre Rios thermal corridor, Federacion is the northern anchor of that route.

Safety & Etiquette
Parque Termal Federacion Safety Tips
Parque Termal Federacion is generally safe for all ages, with lifeguards posted at every pool zone throughout operating hours and a nursing station on site. The thermal water is classified as potable and is regularly monitored and treated, an unusually high standard for a thermal complex.
The source water emerges at 42 degrees Celsius, and while pools are held at lower temperatures, the covered indoor pool operates at around 41 degrees Celsius. Extended soaking in warm water can cause lightheadedness, especially in warm weather. Taking breaks between pool sessions, moving between temperature zones, and staying hydrated are standard practices. The passive pools at 37 to 40 degrees Celsius are appropriate for most adults and older children.
The water contains naturally occurring Radon 222, a geological characteristic of the Guarani Aquifer and within accepted norms for therapeutic thermal use. It is suitable for chronic health conditions but not recommended during acute illness. Visitors with cardiovascular conditions or who are pregnant should consult a physician before soaking. Children should be supervised in all pool areas, and the water park carries the standard risks of slide and wave machinery.
Swimwear is required in all pool areas and showering before entering pools is expected. Lockers are available for valuables. On busy summer weekends the complex can be crowded; the passive soaking zone tends to be quieter if a more relaxed experience is preferred. Families should agree on meeting points before separating across the extensive grounds.
