Kateřinská Cave is one of the most impressive underground spaces in the Czech Republic — home to the largest publicly accessible cave dome in the country and a place where silence, cool air and ancient rock formations create an unforgettable atmosphere. Step through the Gothic portal entrance and prepare to be amazed.

Unlike many caves, Kateřinská is not famous for an abundance of stalactites — its true character lies in its extraordinary scale and unique formations. The Main Dome stretches 97 m in length, 44 m in width and rises 20 m high, and its exceptional acoustics make it a venue for music and choral concerts. Deeper inside you will find the 'Witch' speleothem, the 'Bamboo Grove' of rare, several-metre-tall stick-like stalagmites, and formations known as the 'Sheep', 'Pagoda' and 'Sinter Waterfall'. The cave maintains a steady temperature of around 7°C year-round, so bring a warm layer even in summer.
