Heidewybliloch Cave

The legend of the Heidewybliloch

In ancient times, goblins and forest shrubs lived on the Oberehrendinger Steinbuck, called "s’chlyne Volch" or "Heidevolch" by the locals. People told each other that inside the rock the goblins kept an immense treasure.
Treasure hunters often came from all over the world and tried to find these treasures. Equipped with the latest technical achievements of their time, they set off on the road and thought that it couldn't be so difficult to hunt down a few forest scratches.
An old female hen guarded the entrance to the treasure cave. They sat by the fire and cooked a soup that smelled seductively of fresh wild garlic. Anyone who got this smell immediately forgot why he had come here and went instead to pick wild garlic and carry it home as soon as possible.
But one day a treasure hunter came along who had a terrible cold. So the smell of wild garlic could not bewitch him, he made a determined search and found the treasure happy after a short while. Then the Heidewybli became very angry, stamped his foot angrily on the floor and hurled the soup kettle against the rock face. The mountain opened with a huge crash and the Heidewybli disappeared into it. But the treasure hunter was a generous person, he took something small out of the treasure, put something else in it and left a note with his name on it.
Only on rare days, when the wild garlic makes the slopes of the Steinbuck glow emerald green in spring, does the Heidewybli still come out of its hole and cook a soup over the fire.

Heidenstube

Highlight • Cave

At the top on the northern slope of the Laubberg is a cave in the Nagelfluhwand, which can be reached via a narrow path and stairs. The "Sage of the Heidenstube" found its way into Gottfried Keller's novel "The Green Heinrich".

The Erdmannliloch in the Bachsertal is not just a small cave in an impressive Nagelfluhwand.
Because the remains of the wall come from the Grottenburg Hohfluh, which is the only known cave castle in the canton of Zurich.

Small cave (dug out) with a table and fireplace. Access from the north via ladders.

The route from the bottom is incorrectly navigated; ignore the left turn sign. There's simply a point where there's no way back and the climb is extremely dangerous. There's no solid ground and hardly any way to hold on. We almost called the REGA (Rega Rescue Service).

Arriving at the foot of the Erdmanndliloch is already exhausting enough, climbing the Erdmanndliloch with your biker boots is also a breathtaking effort. Once you've done it😃😀😃
