On the evening of April 7, 2019, the Hungarian Cave Rescue Organization rescued a lost group from the Mátyáshegyi cave. Three young people started the cave-tour with an old caver guide at noon.
The tour began on the easy and popular “Great Circle” cave section, later they aimed at the underground lake that forms the deepest point of the cave. However they got lost in the labyrinth part of the way to the lake, and they could not find the passage neither down to the lake or up that could be got through safely by this group.
According to Hungarian caving customs, all hiking groups have a surface watch, which alerts the cave rescuers if the group fails to reach the surface.
