Buraco das Araras
Mato Grosso do Sul
Buraco das Araras is a remarkable geological formation located in the cerrado of Mato Grosso do Sul, Brazil. This enormous sandstone sinkhole, or doline, measures approximately 500 meters in circumference and plunges about 100 meters deep, making it the largest doline in Latin America and one of only five worldwide with its own ecosystem. The crater features steep walls surrounding a vibrant green lagoon inhabited by broad-snouted caimans. The surrounding forest is rich in biodiversity, hosting over 120 bird species including iconic red-and-green macaws and araçari toucans, as well as mammals such as armadillos, anteaters, and coatis. The sinkhole’s unique ecosystem and geological features are the result of limestone corrosion and boulder collapse, creating a natural habitat that is both visually stunning and ecologically significant. Visitors can explore the site via a gentle 900-meter trail that includes lookout points ideal for birdwatching and photography. The area is protected as part of a private natural heritage reserve, emphasizing conservation and sustainable ecotourism. Buraco das Araras offers a captivating blend of natural beauty, wildlife observation, and geological wonder that appeals to nature lovers and adventure seekers alike.

歴史
The sinkhole known as Buraco das Araras was rediscovered in 1912 by a local worker who named it after the numerous macaws inhabiting the area.
Historically, local legends suggest the site was used as a place to dispose of unwanted individuals, including cattle thieves, which contributed to its mysterious reputation.
The land was acquired in 1986 by Modesto Sampaio, initially for cattle ranching, who later shifted focus to ecotourism in 1996.
Efforts were made to clean the sinkhole, remove waste, and reintroduce native flora and fauna, including releasing macaws back into the area.
In 2007, the Buraco das Araras Private Natural Heritage Reserve was officially established, protecting the 29-hectare site and its unique ecosystem.
