The local experience
A huge sinkhole formed when the roof of a quartzite cave collapsed, about 105 meters deep. Dense forest with giant ferns grows at the bottom, and the walls are used for rappelling.
A lagoon about 5 km from downtown that is the source of the Rio Preto (river), in the São Francisco basin; a Crown tax post operated nearby in the 18th century. Today it is used for fishing, stand-up paddleboarding, canoeing and boat rides.
A 168-meter drop in a municipal park with natural pools, frequent rainbows at the base and camping facilities. It is about 100 km from Brasília, so you can go and come back in a day.
