The Buraco das Araras Private Natural Heritage Reserve (Portuguese: Reserva Particular do Patrimônio Natural Buraco das Araras) is a privately operated conservation area in the state of Mato Grosso do Sul, Brazil.

It takes its name from the Buraco das Araras (Hole of Macaws), a large sinkhole that is the main feature of the reserve.

The sinkhole was vandalized, with the walls and macaws used as targets for guns, and rubbish thrown into the hole including stolen cars.

The hole is occupied by caimans, armadillos, anteaters, coatis, foxes, the macaws for which it is named, ibises, toucans and many other species of birds.

[1] Visitors are accompanied in groups of no more than ten people by a tour guide or local environmental monitor on a walk around the sinkhole.
