Quackenschloss Cave, Passage cave in Wiesenttal, Germany.
Quackenschloss is a passage cave in Wiesenttal with two natural openings that let you walk straight through the rock. The formation sits at about 1,670 feet elevation and was created by water carving through limestone-like layers over time.
The cave was carved over millions of years as water passed through porous rock layers, slowly opening passages. This natural erosion process created the two openings that exist today.
Local stories tell of a hunter entering the cave and encountering supernatural beings, reflecting regional folklore passed through generations in Upper Franconia.
The cave is reached via marked hiking paths that vary in length and difficulty from the starting town. You can choose a short walk or combine it with a longer route depending on your time and fitness level.
The two entrances formed along natural rock fractures that merge into a single passage, creating a rare geological layout. This arrangement lets you enter on one side and exit on the other, making it feel like walking through the mountain.
