You climb down a staircase to the karst gypsum cave, whose water grotto currently has a wonderfully Turkish shimmer. A wonderful natural monument, this place seems almost mystical

The karst lake is struggling with the heat and falling water levels. But it is still a beautiful biotope. The paths to the lake are fantastically beautiful.

Appenrode is the corresponding town, I think. But it doesn't matter, a visit to the Kelle is an absolute must.

The Tanzteich is located northwest of Niedersachswerfen at the foot of the Mühlberg near the road to Appenrode. It is an unusual karst phenomenon, as it is an ancient and originally very deep sinkhole. The body of water, which is around 200 meters long and a maximum of 40 meters wide, is now heavily silted up and is only a few meters deep. On the south bank, the gypsum rock of the Mühlberg rises several dozen meters almost vertically into the air. Numerous legends surround the Tanzteich and try to explain its origin, which was once a mystery to people. Old reports show that the pond had an outlet that was also below the water surface in addition to its underground inflows. If a fisherman came too close to the whirlpool created by this with his boat, the whirlpool would start to dance. The dangerous current of the water threatened to swallow man and boat in a kind of dance of death. For this reason, the body of water was called the Tanzteich. The presumed whirlpool and the underground drain no longer exist today. Today, the Tanzteich is a quiet body of water in the middle of the nature reserve around the Mühlberg. It is also a valuable wetland biotope and a refuge for numerous rare animal and plant species. There was also once a cave in the rock of the Mühlberg directly next to the pond, which was called the Ziegenloch. During the Thirty Years' War, the people of the area hid their small livestock in it from the marauding hordes of mercenaries. Nothing can be seen of this cave today either.
