The Quackenschloss is a passage cave about 18 meters long. It is the remains of a very old and high-lying cave system. The rock wall has a patchy appearance due to the weathering of individual shells. The cave probably gets its name from this rock composition. The type of stone with holes in it (smokewacke) is called quacke here. The oblique oval shape of the cave is determined by two longitudinal fissures and two diagonally sloping bank joints. Two larger fissures cross the passage. One portal is about 7 meters wide and 2.5 meters high, the other, divided by a rock pillar, is about 9 meters wide and 5 meters high. The cave is registered as C 4 in the Franconian Alb Cave Register (HFA). It has been designated by the Bavarian State Office for the Environment as an important geotope (474R060)[1] and as a natural monument (ND-04580). The cave, which is easily accessible via hiking trails, is one of the most frequently visited destinations in the Franconian Jura, also because of its scenic location. There is a sport climbing area next to the cave. Source: Wikipedia

The Quackenschloss is a cave ruin, the remains of which belong to a very high (505 meters) and therefore very old cave system. The rock grotto, which is about three meters high and six meters wide, is open on two sides and can be safely entered from the east side. In the gallery cave, which takes its name from the enclosed fossils, the so-called Quacken, the remains of a 17-meter-long cave system can be explored.

If you want to illuminate them with tea lights, you should take a whole bag with you. And a rubbish bag: for the burned-out little lights. Attention, it is slightly slippery on the greasy stones... Have fun!!

A must-see, large "cave" and not for nothing one of the 100 most beautiful geotopes in Bavaria. The extensive karst cave was created by the collapse (collapse) of the former cave ceiling. The steep climb is worth it.
