Buraco das Araras (Mato Grosso do Sul)

Buraco das Araras is a huge sandstone crater, a geological formation created by the collapse of boulders. It is about 500 m in circumference and 100 m deep, located in the middle of the cerrado in the state of Mato Grosso do Sul in Brazil. It is home to a wide variety of birds, especially araçari toucans and red-and-green macaws, hence the name of the cave.

According to the decree of IBAMA of 11 April 2007, the crater is part of the 29-hectares Buraco das Araras Private Natural Heritage Reserve (RPPN) and is connected to the RPPN Rio da Prata with 307 hectares.
