Our Guides

What the heck is a bear guide?

50 years of tunnelling have already brought forth some unusual stories. Nobody knows exactly how long the term "bear guide" has been around in the tunnel.

According to the legend, the term comes from: A tunnel leads into the mountain like a cave for the bear, who then safely protects his "pack" there and also leads it out again.

The catch? In the animal kingdom, bears are usually solitary animals and when in a group they are officially called detectives or sloths. But our Stollen Guides or "bear guides" are anything but lazy.
