Thermas dos Laranjais

Thermas dos Laranjais opened in 1987 in Olímpia, São Paulo state, and has grown into a 300,000-square-metre park with more than 55 attractions, ranked as the most-visited water park in the Americas and the second most-visited in the world in 2023, drawing over two million visitors annually. Its defining feature is its circulating hot water drawn from the Guarani Aquifer, making it fundamentally a thermal-springs destination rather than a conventional water park. A major expansion in 1997 added the park's first water slides, broadening its appeal beyond pure thermal relaxation to include adventure attractions for families and teens.
