Caldas Novas Park Piranhas

Caldas Novas Park Piranhas is one of the many thermal water park facilities that make Caldas Novas in Goiás state the world capital of thermal leisure tourism — the largest concentration of thermal water parks on Earth, where the entire economic and social life of a city of 100,000 inhabitants has been built around artesian hot springs that emerge at 37–52°C from deep aquifers beneath the cerrado savanna. Park Piranhas, named for the fish that inhabit the cooling water channels, is part of this extraordinary ecosystem of thermal leisure in which visitors float, slide, swim and soak in naturally heated bicarbonate-sodium mineral water across dozens of private and public facilities. The greater Caldas Novas thermal district, encompassing both Caldas Novas city and the adjacent Rio Quente municipality with its Parque das Fontes Quentes, represents an economic and recreational phenomenon unique in global thermal tourism, attracting over three million visitors annually from across Brazil and South America.
