    Mountaineering

    The Hölloch is the 77-meter-deep entrance shaft into a 12,900-meter-long karst cave. It is not open to tourists. From the top, you can see a few meters into the shaft, but nothing more.
    The Hölloch is located in the Bavarian part of the Mahdtal valley, in the municipality of Oberstdorf.

    The entrance to the second longest cave in Germany after the huge dumping pit. However, you do not see much except the first meters of the entrance shaft.
