As long as the L170 is closed, the caves can be viewed in peace.

Recently a lot of green was removed so that you can see even more entrances to caves. There are a few holes in the chain link fence so that you can also get in. However, inside the entrances to the "hall" or possibly other rooms are unfortunately bricked up. I guess because of the risk of collapse, because there have been landslides in this area.
