The Parque da Cascata (meaning Waterfall Park in Portuguese) is the popular name of Parque Florestal Municipal de Sete Lagoas located at Serra Santa Helena, just 3 km (2 mi) from downtown Sete Lagoas, Minas Gerais, Brazil.
[1] The gorge of the waterfall in the Parque da Cascata is in fact the collapsed part of a karst cave.
Following the brook one sees a number of horizontal stalactites and stalagmites that clearly demonstrates that part of the cave has collapsed.
The limestone area north of Belo Horizonte is called the Sete Lagoas Formation.
The area around Sete Lagoas has many caves, of which the Gruta Rei do Mato is the most famous one.
