Rybenské Perničky

Rybenské Perničky is a small yet striking nature reserve in the Vysočina Region of the Czech Republic, located roughly two kilometers west of the village of Pustá Rybná, in the Svitavy district. Covering just under 7.4 hectares, the protected area consists of two separate rock groups made of orthogneiss, rising to heights of about 16 and 8 meters, set within a forested hillside reaching almost 750 meters above sea level.

Where does the name come from?

The name "Perničky" refers to the bowl-shaped hollows visible on the rock surfaces. In Czech, "pernice" describes a type of rough-surfaced mortar traditionally used for grinding poppy seeds, and the resemblance between these natural depressions and that household tool gave the rocks their name. On top of the eastern rock formation there is a horizontal ledge with three such natural basins, the largest measuring about 60 centimeters across and 20 centimeters deep. These features formed through frost weathering during the Quaternary period and are the main reason the site draws the attention of geology enthusiasts and nature photographers alike.

How did the rocks form?

The rock massif at Rybenské Perničky is made up of two distinct blocks separated by a shallow dip in the terrain. Their jagged, weathered profile results from centuries of frost and water action gradually breaking apart the orthogneiss, carving vertical walls, cracks, and the characteristic erosion basins mentioned above. This kind of rock formation is typical of the granite-gneiss highlands found across the Bohemian-Moravian Highlands, the broader upland region that includes the area around Pustá Rybná.

What else is there to see nearby?

The reserve falls under the administration of the Nature and Landscape Protection Agency of the Czech Republic, specifically the regional office managing the Žďárské vrchy Protected Landscape Area. The forest surrounding the rocks provides habitat for a number of bird species associated with older woodland, including black woodpecker, tawny owl, and the less common spotted nutcracker. This variety of birdlife makes the site appealing not only to hikers and climbers but also to birdwatchers passing through the region.

The rocks are also known within the Czech climbing community, appearing as a listed climbing sector in the national climbing association's catalogue. However, because the site holds nature reserve status, climbing activity here is subject to restrictions tied to its protected status.

Is it worth a visit?

Rybenské Perničky suits travelers looking for a quiet, off-the-beaten-path stop in the heart of the Bohemian-Moravian Highlands — away from crowds, but rich in geological interest and offering an easy short walk through the forest. It works well as an add-on for anyone already visiting the nearby village of Pustá Rybná or hiking through the wider Žďárské vrchy area.
