Caldas de Prata, or Silver Springs, is a thermal spa resort in the Goiás State thermal zone of Brazil, where naturally heated mineral spring waters emerge from the vast geothermal field underlying the Brazilian Central Plateau in one of South America's premier thermal bathing regions. The state of Goiás is home to one of the world's largest concentrations of natural thermal springs, with the hot spring complex centered on Caldas Novas and Rio Quente drawing millions of visitors annually to what is marketed as the world's largest hot spring resort area. Caldas de Prata contributes to this exceptional thermal heritage, offering visitors the recreational pleasures of naturally heated mineral bathing in the warm, welcoming environment of Brazil's heartland thermal region.
Insider tip — Caldas De Prata lies in the highlands of Rio Grande do Sul in southern Brazil, where geothermal activity produces gently heated mineral waters used for centuries by local communities. The surrounding landscape of Araucaria pine forests and rolling grasslands gives the site a distinctly southern character quite unlike other Brazilian thermal destinations. The moderate climate of the region means the pools are enjoyable year-round without the intense humidity of tropical thermal parks. The silver-clear waters that give the spring its name are notably low in sulfur, making them comfortable even for those sensitive to strong mineral odors.
