Mordloch, Cave system in Baden-Württemberg, Germany.
Mordloch is a cave system in the limestone of the Swabian Jura with tunnels, chambers, and underground lakes that extend deep underground. The public walking section covers only the entrance portion, while the full passages continue much deeper into the mountain.
The cave has been explored over many decades, but a major incident in 1977 brought it into public focus. This event led to changes in how people understood the dangers and safety needs within such cave systems.
The name comes from a local legend about someone who hid a secret in these caves long ago, and the story became part of how people in the region understood this place. Such tales shaped how visitors and locals think about caves in the Swabian landscape.
Waterproof shoes and a good light source are essential, as the passages can be slippery and lighting helps you see the formations and navigate safely. Keep in mind that heavy rainfall causes water levels to rise quickly, which can make parts of the cave inaccessible.
Deep inside the cave is a large chamber called Gammahalle that rises vertically through several layers of limestone. This chamber reveals how different rock layers formed over long periods and tells the geological story of the area.
