Caverna do Diabo State Park, Protected cave system in Eldorado, Brazil
Caverna do Diabo State Park is a protected reserve with Atlantic Forest vegetation spreading across four municipalities and featuring rivers, waterfalls, and varied wildlife. The underground system displays large limestone formations with stalactites and stalagmites, especially in a chamber known as the Cathedral Hall.
The cave was discovered in 1896 by Ricardo Krone, who mapped the underground passages by following the Rio das Ostras river. This discovery led to recognition of the site's importance as a natural and geological treasure.
Local quilombo communities live within the park region, maintaining settlements that date back to the period when enslaved people found refuge in these forests. Their presence shapes how the landscape is used and respected today.
Access to the cave requires joining a guided group to ensure safety and preserve the space. The illuminated pathways make it straightforward to walk and observe the formations without needing special equipment.
The underground system extends far beyond what visitors explore, with sections that remain largely unmapped and scientifically studied. Much of the hidden passages continue deeper into the mountain and have not been fully documented.
