Blue Lake Cave, Natural cave system with underground lake in Bonito, Brazil
The cave extends over 2000 meters underground, featuring a central chamber with a 90-meter-deep lake surrounded by white limestone formations.
Scientists discovered Pleistocene mammal fossils near the cave, including remains of giant sloths and saber-toothed tigers from 12,000 years ago.
The Brazilian government designated this cave system as a Natural Monument in 1978 through the National Institute of Historic and Artistic Heritage.
Visitors must join guided tours with certified guides from Bonito municipality, following specific protocols to maintain the cave's natural state.
Between September and February, sunlight entering through the 40-meter-wide entrance creates an intense blue reflection in the underground lake.
