The park's sandstone formations were shaped by erosion during the glacial periods of the Paleozoic Era.
Furnas are deep, circular sinkholes formed by the collapse of underground caverns, some containing internal lakes.
The area is home to the Araucaria angustifolia, a tree species endemic to the southern Brazilian highlands.
It acts as an essential water catchment area for the tributaries feeding the Tibagi River.
The park is categorized as an Integral Protection Conservation Unit under Brazilian environmental law.
Campos Gerais National Park is a protected area situated in the state of Paraná, Brazil, specifically within the municipalities of Ponta Grossa, Castro, and Carambeí. The park preserves a unique landscape defined by rocky sandstone formations known as 'furnas' and extensive grasslands interspersed with Araucaria forests. These circular-shaped sinkholes, or furnas, reach depths of over 100 meters and serve as distinct geological markers of the region. The park facilitates the conservation of the Atlantic Forest biome and the specific Campos Gerais ecosystem. Visitors encounter deep canyons and natural pools carved by the flows of the Tibagi River basin. It covers approximately 21,000 hectares of diverse terrain. The geological history dates back to the Paleozoic era, featuring fossils that contribute to its scientific significance.
The observation decks overlooking the larger furnas sinkholes provide the most comprehensive vantage points.
Carry specialized hiking gear as trails often involve uneven, rocky, and potentially slippery terrain.
Bring sufficient water and sun protection, as large sections of the grasslands offer limited natural shade.
Verify the status of specific trails before departure, as maintenance or heavy rainfall can cause temporary closures.
Attempting to descend into the furnas without authorized guides or proper climbing equipment.
Closed on Mondays for maintenance; may close during periods of extreme fire risk or heavy storms.
Wear sturdy, closed-toe hiking boots; stay strictly on marked paths to prevent soil erosion and ensure personal safety.
