The road contains the largest rock cut in Brazil, created to carve a passage through the sandstone formations.
The name 'Corvo Branco' (White Crow) refers to a species of birds once observed nesting in the white sedimentary cliffs.
The pass sits at a crucial geographical transition point between the Atlantic Forest and the Araucaria moist forests.
The descent features an average gradient of approximately 10% to 12% in its steepest sections.
Heavy fog and rapid meteorological shifts are common due to the convergence of air masses from the Atlantic and the plateau.
Serra do Corvo Branco is a mountain pass located on the SC-370 highway in the state of Santa Catarina, Brazil, notable for having one of the steepest paved road descents in the country. The route is defined by two massive vertical sandstone walls that narrow the passage, creating a dramatic corridor at an altitude of approximately 1,175 meters. The road connects the plateau region of Urubici with the coastal valley of Grão-Pará. It is widely recognized for its winding layout, sharp hairpin turns, and restricted width, which presents significant challenges for heavy vehicle traffic. The area is part of the Serra Geral mountain range and is characterized by its geological formation of sedimentary rock cliffs. Travelers experience a drastic change in climate and vegetation as they descend from the high altitude plateau to the lower tropical forests.

Check local weather reports for fog conditions, as visibility can drop to zero within minutes.
Ensure your vehicle's braking system is in top condition before attempting the descent.
Use low gear (engine braking) throughout the entire descent to prevent brake overheating.
Do not attempt the drive in low-visibility conditions or during heavy rain, as the road is prone to landslides and becomes extremely slippery.
Occasionally closed during extreme weather events or after heavy rainfall for safety inspections.
Maintain high awareness of oncoming traffic as the road width is extremely narrow at the sandstone cut; yield to ascending vehicles when possible.
