Situated in the Demanovska valley northerly to the Demanovska Cave of Liberty, in the National Nature Reserve Demanovska Valley, in the territory of the Low Tatras National Park. The cave was created in the Middle Triassic limestones by the former ponor flow of Demanovka, at three developmental levels. It is 1,975 m long. Ice filling occurs in the lower parts of the cave. Ground ice, ice columns, stalactites and stalagmites are present.

A finding place of bones of various vertebrates including speleal bear (Ursus spelaeus), that were erroneously taken for dragon bones in the 18th century. The cave has been known since the time immemorial. The cave was surveyed by G. Buchholtz Jr in 1719-1723. Numerous inscriptions on its walls and a lot of preserved rich literary resources evidence a great interest about this cave. The cave was open to the public in the eighties of the last century, and reopen in 1950-1952. Currently, publicly accessible are 650 m.

The show path goes through mighty river passages interconnected by steep sections. The first part of the tour leads through cave spaces with flowstone decoration and the second part is in the iced spaces of the cave.

The combination of flowstone and ice decoration offers a very interesting tour for visitors, where they can learn on forming cave spaces, cave decoration and conditions for glaciation and also on the influence of ice on original calcite fill. The cave spaces consist of oval, river modelled passages and domes reshaped by collapses and frost weathering.
