simply wonderful

The Grundlose Grube > a geotope The Grundlose Grube is less of a sinkhole than a shaft cave. It is an approximately 35 m deep shaft with a 3-4 m wide opening. The funnel-shaped opening lies in the green sandstone; after 6 m, the boundary with the Jurassic limestone is reached. Here, the shaft widens to 7-9 m. From this depth, it narrows increasingly. The floor is filled with loose material. The Grundlose Grube belongs to the karst features of a younger (Quaternary) age. The Grundlose Grube is a bat roost of European importance. To preserve the cave as a year-round habitat, there is a YEAR-ROUND ENTRY BAN! Speleological exploration is possible in individual cases, but requires a special permit. The contact person is the Lower Nature Conservation Authority at the Kelheim District Office. Bavarian State Office for the Environment (LfU). https://www.umweltatlas.bayern.de/standortauskunft/rest/reporting/sb_geotope/generate?additionallayerfieldvalue=273H002 Further information and images can be found on the website below. https://www.lochstein.de/hoehlen/D/fralb/sfralb/H-Hemau/Grundlose%20Grube/grundlose.htm

The tour through the cave is really interesting and entertaining. When the lights are turned off in the cave, it is completely dark 😃.

Beautiful stalactite cave, unfortunately you are not allowed to take photos. At the end of the tour there is a multimedia show which is very well done.

The small and large cow troughs are not natural ponds, but rather a clay pit from the 18th century. Because this soil does not allow water to pass through, a pond was created that used to provide water for people and especially animals. Since settlers used the forest as pasture, they called the watering hole “cow trough”.

Kind of impressive. But be careful, if you fall into this you won't have to order any new shoes

Very nice place with a magnificent rocky background

Reaching the Blautopf is not easy, a narrow path leads down. The view from the hiking trail is quite overgrown and you don't get to see the full beauty of the Blautopf.
