Rudické propadání

Rudické propadání is one of the most distinctive karst features in the Moravian Karst, located near the village of Rudice on the Drahany Highlands in the South Moravian Region of the Czech Republic. It marks the spot where the Jedovnický Brook disappears underground, sinking into a vast network of subterranean passages.

What is Rudické propadání?

Rudické propadání is a natural karst sinkhole — a "ponor" — through which the surface water of the Jedovnický Brook flows into the interior of the limestone massif. Together with the Býčí skála Cave, it forms a single connected underground system whose explored passages exceed 13 kilometers in total length, making it one of the longest cave systems in the Czech Republic. The site lies within a protected natural area, reflecting its geological and ecological significance.

Why is this place remarkable?

The link between the sinkhole at Rudice and the resurgence several kilometers away at Býčí skála Cave is one of the classic examples of underground karst water flow in Central Europe. Water that vanishes at Rudické propadání travels through a complex network of passages and siphons before re-emerging at the surface near Býčí skála. This underground connection has been the subject of extensive speleological research, dye-tracing studies, and cave exploration that helped map the true course of the water between the two sites.

The sinkhole itself is impressive in scale — a deep, steep-sided depression where the ground abruptly gives way and the stream vanishes into cracks in the rock. The surroundings display features typical of the Moravian Karst: limestone outcrops, karst depressions, and dense forest covering the slopes of the valley.

What does the surrounding area look like?

Rudické propadání sits at the heart of the Moravian Karst, a region famous for its dense network of caves, gorges, and karst valleys, including the renowned Macocha Abyss. The area is a popular destination for hikers and cyclists, with trails connecting it to other karst attractions such as the Punkva Caves and Býčí skála itself. The forested terrain around the sinkhole gives it a quiet, natural character despite its proximity to well-traveled tourist routes.

Can visitors explore Rudické propadání?

The sinkhole itself can be observed from the surface, reached via a trail that passes through the area near the village of Rudice. The interior of the cave system, including the connection to Býčí skála, is not open to the general public as part of a standard tourist route — exploring the deeper sections requires speleological training and appropriate permits. For most visitors, the appeal lies in seeing the spot where a stream suddenly vanishes into the earth and in appreciating the scale of the extensive cave system hidden beneath the surface.
