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.

At the Ramsflue above the sleepy hamlet of Hard, there is a small cave between high limestone towers. A beautifully laid out forest walkway leads past it. According to legend, dwarves used to hide there. Anyone who dares can enter the cave. Happy, colorful little fellows and dangerous tigers await the visitor ;-)

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.
