More easily accessible than many of Goiás’s attractions, the thermal resorts of Caldas Novas, around 185km south of Goiânia, are incredibly popular with Brazilians from beyond the state. It claims to be one of the world’s largest hot-spring aquifers, a massive and very hot natural subterranean reservoir. The healing reputation and the sheer joy of relaxing in these natural spa resorts lure plenty of people from the urban sprawl of the São Paulo region. While some people do come for long, expensive courses of treatment, most visitors are simply here on holiday, relaxing, sunbathing and taking the waters for a few days or a week.
