On the afternoon of February 23, 2019, Zoltán B., a 34-year-old tourist, equipped with a headlamp, climbed into the Papp Ferenc Cave which is on the border of village Pilisborosjenő, on the side of hill named Ezüsthegy. He spent about four hours in the cave and then headed out.
He got lost in the infamous, clothesline rubble labyrinth formed in the sandstone beneath the entrance, being unable to find a way out.
This place is extremely deceptive, you can even hear his voice from the surface, there are places where you can see the light of his lamp between the stones, everything seems to be very close - but in the narrow gaps where the sound and light still come through, it is very difficult to find the only path to the surface where there is enough place to get out.
