The show cave Heimkehle, located in the picturesque landscape of the Südharz, is one of the about 200 well-known caves in the karst landscape of the Südharz. The cave has a length of about 2km, whereas the way that is open to the public for guided tours has a length of 600m. Guided tours start and end in the exhibition area in the gallery next to the cash point. This gallery has artificially been created and it hosts two exhibitions and it is the meeting point for visitors. Beginning with the little Dom, the guided tour continues through the so-called Riegelgang to the Großer Dom, passing through the big tunnel into the Thyra hall and to the Thyra lake and back. A music presentation with lightning effects awaits the visitors in the Große Dom, before the guided tours end in the little Dom at the memorial site. From there visitors will be guided back to the starting point within the exhibition hall.
