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.

The steep path to the quarry has been washed out and is very rocky due to the heavy rain in recent months. Each biker has to decide for themselves whether the stairs at the end of the trail are rideable.

Very very steep trail, not for beginners, descending steeply is the only right option for me

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