Fervedouro Bela Vista, located in São Félix do Tocantins in the Jalapão region of Brazil, is a natural spring famous for its crystal‑clear waters and unique buoyancy. Visitors can swim or float effortlessly in the pool, enjoy the surrounding cerrado vegetation, and take photographs of the striking blue tones created by the underground water pressure. Notably, the spring is around 15 metres deep, yet due to its strong upward flow, people cannot sink, making it a safe and fascinating experience. The site also offers camping facilities and a restaurant, making it a popular stop for eco‑tourism in Jalapão.
