Thermas is a thermal park in Brazil's interior, part of the country's renowned water park and thermal resort sector centered particularly in the state of São Paulo, where municipalities such as Olímpia, Caldas Novas, and Rio Quente have become internationally recognized thermal destinations attracting millions of domestic and international visitors each year. Brazil's thermas culture combines geothermal mineral springs with large aquatic leisure infrastructure, creating a uniquely Brazilian form of thermal tourism that blends health, family recreation, and hospitality in the warm tropical climate. The parks draw on deep artesian aquifers and geothermal sources to supply consistently warm mineral-rich waters throughout the year.

Water temperatures hover around 38°C, making the pools comfortable year-round in the subtropical Brazilian climate. The site caters primarily to families and weekend visitors from São Paulo city, about 160 km to the southeast.
