After rock shedding was discovered near the Column Grotto in the fall of 2022, the municipality carried out various investigation and remediation work. During this time, the sandstone cave was closed. The investigation and remediation work has since been completed. Thus, there is essentially no longer any safety risk while in and around the Column Grotto. Every effort has been made to prevent any further rock shedding. However, a residual risk of natural hazards cannot be completely ruled out.

Sandstone was mined here for a long time. Be careful when visiting, the area is on the edge of the shooting range. The caves are not accessible when shooting is on! Here is some useful information about sandstone mining in Staffelbach. https://sandsteinmuseum.ch/

The area was cordoned off when we visited, so it was really just for pictures, sadly.

In the 20m deep Nagelfluh cave, you can still stand comfortably at the beginning, but further back you can only continue on your knees.
