History and present
The cave was discovered by A. Král with the help of A. Mišura and other surveyors through the dry lowest ponor of Demänovka River in 1921. The Commission for Publicizing of the Demänovské Caves was established in 1922 and began the development works for opening for the public. An interim electrical lighting was installed in 1923. A part of the cave, leading from the entrance gallery through the Marble Riverbed and Great Dome up to the Golden Lake, was opened for the public in 1924.
The Cooperative of the Demänovské Caves originated in 1925 and continued in the work of the Commission. An expedition headed by A. Král discovered in 1926 the Jánošík’s Dome, Virgin Passage, Passage of Suffering and the Red Gallery. V. Benický and A. Lutonský discovered the Magical Passage and Violet Dome in 1927, Svantovít’s Halls in 1929, and one year later the Miraculous Halls. A new entrance to the cave was dug out in 1928 in the Točište Valley, which was opened to public in 1930. A new permanent electric lighting was installed in 1931 and the show path was prolonged as far as the Pink Hall with a fork into the Hviezdoslav’s Dome. The same year J. Zelinka discovered the Bear’s Passage and found out its communication with the surface. A new exit from the cave was dug out in 1933 from the Bear’s Passage, which changed the show path. The upper parts of the Hviezdoslav’s Dome were opened to public in 1931 – 1933. During 1948 – 1955 were the caves of the Demänovská Valley surveyed and measured by A. Droppa. Under his leadership in 1951 the Demänovská Cave of Liberty was connected with the Pustá Cave, and in 1983 the speleodivers V. Žikeš and Ľ. Kokavec found its connection with the Vyvieranie Cave. Several unsuccessful attempts in 1952, 1968, 1974 and 1983 were altered with a successful one on the turn of 1986 and 1987 when its natural connection with the Demänovská Cave of Peace was reached. The cavers from the group of the Demänovská Valley found its connection with the Cave Under the Cliff and Valley Cave in 1989, and the connection with the Cave of Ruins in 1992.
The length of path open to public is 1,800 m. Vertical difference between entrance and Ground Floor is -66 m, and between the Ground Floor and exit +85 m.
