The length of the cave is 3,829 m with a height difference of 168 m. Chimney spaces leading from the upper, original entrance, situated 82 m above the current entrance, open into the entrance parts, accessible through a pierced tunnel. The ascent and descending parts of the tour route, conditioned by the interlayer areas of limestone, rise from the Crossroads and in some places are widened by routing into the dome-shaped and hall-like areas (Ruined Dome, Dome of the Ruins). Oval shapes of water modeling have been preserved in several sections (Tubular Dome, Long Corridor, Abyss Corridor). The considerable vertical fragmentation of the cave is completed by abysses (Hunger Abyss, Hell) and chimneys.
They are attracted by sinter waterfalls (High Dome, SNP Dome, Waterfall Dome, Music Hall) and pagoda-shaped stalagmites (Palm Hall). Other forms of sinter filling (Gallery, Jewelery, White Hall) are also richly represented. The air temperature is 5.0 to 6.3 ° C, relative humidity 90 to 97%.
7 species of bats were found in the cave. The dominant is the common bat (Myotis myotis). Rare are the bearded bat (Myotis mystacinus), the Brandt bat (Myotis brandtii) and the ciliate bat (Myotis emarginatus). Bathynella natans lives among the small invertebrates in the lakes.
