Caldas Novas

Caldas Novas needs 2 days: touring the thermal water parks, with slides and pools fed by natural springs reaching up to 60°C, is nearly the sole reason to visit. April-September brings the driest weather, though the thermal waters are enjoyed year-round. It's mid-priced by Brazilian standards, with all-inclusive resorts the dominant option. It holds the world's largest thermal water reserve by volume, of unique geological origin -not volcanic, but from the depth of its granite layers-, which made it Brazil's main thermal tourism destination, with hotel capacity to host more tourists per year than the city's own population.
