The 300 m long course of a former underground river has been a show cave since 1906. After its renovation in 2005, it is regarded as one of the most modern show caves in Germany and impresses with lighting technology which emphasises the character of the cave. Very navigable, with extraordinary dripstone formations and mineral deposits.
