The underground stream travels approximately 12 kilometers through the cave system before emerging at the Býčí skála resurgence.
The cave entrance and its massive sinkhole are formed in Devonian limestone, which dates back over 360 million years.
The sinkhole's primary vertical wall is a prominent location for geological studies of the Moravian Karst's subterranean hydrological cycles.
Exploration of the system requires professional speleological equipment due to submerged passages and siphons.
The water levels in the sinkhole fluctuate drastically during heavy rainfall, often flooding the lower accessible areas.
Rudické propadání is the second-longest cave system in the Czech Republic, functioning as a massive karst sinkhole where the Jedovnický potok stream disappears into a 90-meter deep abyss. The site features a 35-meter high rock face that marks the entrance to a complex subterranean drainage network. The underground stream eventually resurfaces near Býčí skála cave after traveling through a series of galleries and siphons. The surrounding area is protected as a nature monument within the Moravian Karst Protected Landscape Area. Geologically, the site provides evidence of extensive limestone erosion and underground water flow evolution over millions of years. It serves as a primary drainage point for the Jedovnice basin.

Wear sturdy hiking boots with aggressive tread as the limestone trails are frequently damp and slippery.
Bring a headlamp if you plan to explore the areas near the base of the sinkhole, as sunlight does not reach the deeper recesses.
Visit after a dry period to ensure the trails leading down to the water-disappearance point are safely passable.
Attempting to enter the cave passages beyond the main sinkhole entrance without proper caving equipment and cave rescue permits.
Open year-round, but access to the sinkhole base may be restricted during periods of high water or flooding.
Stay on marked trails to avoid damaging fragile karst surface formations; do not enter the cave tunnels without authorization.
