On Monday, 28 September 2026, a public holiday in Czechia, all 13 of the country's operating caves will open their doors to visitors — even though some of them are normally closed on this particular day. This was announced by Pavel Hejdoš, spokesman for the Czech Caves Administration. Thanks to this, it will be possible to visit the karst underground on any day of the long weekend. The air inside the caves has a humidity of around 99%, which is beneficial for the respiratory tract.
Meanwhile, voting for the best shots from the summer photo contest continues on www.caves.cz. The jury of the Caves Administration selected ten finalists from among the entries submitted by holidaymakers — the photos come with amusing and original captions. "We are now putting them to a public vote; voting closes on 30 September," said Milan Jan Pucek, director of the administration.
The Balcarka Cave is preparing a "School for Young Speleologists" for Saturday, 26 September — a programme for children aged five and up and their parents. Due to high demand, the main date is almost fully booked, so the organisers have added another day: Saturday, 10 October. Interactive tours will run all day, from 9:00 to 16:00. "Take the course and get your young speleologist's certificate," the organisers invite. Participation requires advance booking by phone at 516 444 330.
Among the caves that attract the attention of tourists in Czechia are the Bozkov Dolomite Caves in the Podkrkonoší region, home to the country's largest underground lake; the Koněprusy Caves in the Bohemian Karst near Beroun, with a preserved medieval counterfeiters' workshop; and the unusually coloured Chýnov Cave near Tábor. In the Olomouc Region, it is worth visiting the richly decorated Javoříčko Caves, the Mladeč Caves near Litovel with traces of a Cro-Magnon settlement, or the hydrothermal Zbrašov Aragonite Caves near Přerov. In the Jeseník region are the Na Špičáku Cave, with its romantic heart-shaped corridors, and the Na Pomezí Cave, which is closed for reconstruction until November 2026. Beneath Pálava, the Na Turoldu Cave in Mikulov is notable for formations resembling coral reefs.
In the Moravian Karst, besides the best-known Punkva Caves, with their electric-boat ride along the underground river and a view into the Macocha Abyss, visitors can also explore the multicoloured Balcarka, the Kateřinská Cave with its vast halls and the dripstone formation known as the "Witch," and the Sloupsko-Šošůvské Caves with their deep chasms. The Výpustek Cave near Křtiny holds a history spanning from the Palaeolithic through the mining of phosphate clays and a Nazi fighter-plane factory to a secret Cold War-era military command post. At Výpustek and the Sloupsko-Šošůvské Caves, in addition to the regular routes, adventure tours are also offered, in which participants wear helmets and squeeze through narrower and lower natural passages.
