    Mountaineering

    The Hölloch is the 77 m deep entrance shaft into a 12,900 m long karst cave. It is not developed for tourism. From above, you can look a few meters into the shaft, but no more.
    The Hölloch is located in the Bavarian part of the Mahdtal valley, in the municipality of Oberstdorf.
