The Hoelloch cave is growing and growing – speleologists discover a new spectacular connection, wich results in a an explored length of about 207 kilometres !
Between the deepest (551 m) and the highest (1584 m) point of the world-famous cave system there are now 1033 metres of altitude difference – a new world record!
There are a few longer caves in the world, but they are all less than 1000 meters deep. Therefore the dimensions of the Hölloch are unique like nowhere else in the world.
