The world’s largest limestone mine. An endless maze of galleries with caves as large as cathedrals and narrow paths where an adult man cannot walk upright.
An enormous 60 km labyrinth of passageways with caverns as large as a cathedral, and narrow tunnels where you have to walk doubled up. 2 km of the passageways are lit. A multi-media presentation shows the history of the mines. Exhibitions and films tell about bats, geology and mining.
Groups are granted admission all the year round with prior reservation.
Guided tours in Danish, English and German can be arranged.
