Near the village of Křtiny lies Výpustek Cave, with a colourful and turbulent history. As early as 1938, the underground space was taken over by the Czechoslovak army and used as a munitions depot. Many chambers and rock partitions were blasted away, turning natural cave passages into grim tunnel spaces. During the war, the cave was occupied by the German army, who set up an underground factory producing aircraft engines.
After the Second World War, speleological surveys were carried out in the reopened Babická Passage. After the cave was taken over by the Cave Administration of the Czech Republic and reopened in 2008, it became accessible to visitors of Moravian Karst.
Since 2022, the "Secrets of the Cave" adventure tour is available, for which advance booking is required. We highly recommend making time for a visit to Výpustek during your stay.

What will you see at Výpustek Cave?
The tour begins in the entrance hall of the former military barracks, where visitors learn about the rich and turbulent history of this site. From the hall, you descend into a concrete bunker, a former reserve command post of the Czech and previously Czechoslovak army. You then enter the cave itself, heavily marked by human activity. Extensive excavation to convert the cave into a German underground aircraft engine factory transformed the original small spaces into today's massive tunnels and halls. Next comes the Babická Passage, from which a ventilation shaft leads to the surface – used during the Second World War to ventilate the underground factory.
Of particular interest are the remains of the German boiler room. It was coal-fired, and according to witnesses, floor channels heated the air throughout the entire underground factory to 17–20 °C. The route continues into Jindřich's Hall, whose dark walls and ceiling are covered with young stalactite formations – drinking straw stalactites and cave curtains. The hall also has excellent acoustics. The exit passes through three natural, unmodified passages (opened in 2010 and 2013), where you can see the original cave floor level before the excavation of clay, and look into two abysses up to 20 metres deep.
When visiting Výpustek Cave, we recommend stopping in Křtiny to see its magnificent baroque church, designed by Jan Blažej Santini. Afterwards, you might take a swim at the outdoor pool in Jedovnice, or visit the speleology museum in the windmill at Rudice. More information is available at the Rudice information centre.
