There is a beautiful legend about this rock, which is translated as 'The Weeping Rock'. It tells of a forbidden love between a nobleman and a young peasant girl. The nobleman's father did not want to allow this love affair, but a fairy allowed the couple to meet in the forest. When the father saw them in the forest, he said that it must rain from this rock, then his son would be allowed to marry his beloved. At that moment, the rock began to drip, and so they became a happy couple.

I confirm, access to the trail is closed until ..... given the inventory, reopening does not seem to be a priority.

Before mid-July there is usually too much snow at the lower entrance to the cave so that one cannot get into the cave. Inside, cat eyes help with orientation.
