Who takes you there
People from Peruaçu guiding visitors from afar
Janela do Sertão was born in Januária in 1997, when Cavernas do Peruaçu National Park was still a secret known to few. We are guides, drivers and hosts from the region.
We handle everything: we pick you up at the airport or your lodge, drive you safely along the valley roads, and lead every trail to the caves with ICMBio authorization (Brazil’s federal conservation agency). All you have to do is look up.
The destination
One of the largest cave sanctuaries on Earth
Cavernas do Peruaçu National Park holds monumental caves, thousand-year-old rock paintings and a canyon carved by the river in the heart of northern Minas Gerais.
Gruta do Janelão
Chambers up to 100 meters high, with natural skylights that split the rock and flood the interior with light.
Rock paintings
Traces of the peoples who inhabited the valley thousands of years ago, preserved on the cave walls.
Peruaçu Canyon
Limestone walls, dry forests and springs that form one of the rarest landscapes of the Brazilian cerrado.
