Kalkberghöhle, Show cave in Bad Segeberg, Germany.
Kalkberghöhle is a show cave in Bad Segeberg that extends through a major gypsum cave system, one of the longest of its kind in Germany. The accessible section spans several hundred meters and displays impressive gypsum formations and chambers throughout the route.
The cave was discovered in 1913 during quarrying operations and received natural monument status in 1930. This protection led to the permanent end of mining and transformed the site into a public attraction.
The cave theater was built between 1934 and 1937 and hosts performances of Karl May adventure stories each year. These shows have become a popular seasonal tradition for both locals and visitors who gather to watch tales of frontier adventures.
Visitors are guided through approximately 600 meters of the cave system in tours lasting about 35 minutes, with well-lit and safely maintained pathways. The cave remains open year-round, though most visits occur during the warmer months.
The cave houses approximately 20,000 bats from eight different species and provides habitat for a rare beetle species found nowhere else in the region. This wildlife makes the site an important refuge for specialized cave-dwelling creatures.
