Wonderful geological and botanical feature. With a detour from the hiking trail you can make a spectacular loop under the rocks and in the special flora. You can then climb up again on a stairway to the hiking trail in the direction of Hochwacht.

Not much to see here, as the cave has an extremely narrow opening. You have to go a bit off the path to find it; it's adjacent to a camping site.

Geologically remarkable spring that rises directly from the sandstone rock in a cave. The name has been documented since 1327 and commemorates the Irish monk Pirmin († 753), founder of the Reichenau monastery and patron saint of the old Pfungen parish church. According to tradition, he stayed in the area and is said to have settled temporarily at this or a neighboring spring. Support for the cave ceiling and access rebuilt in 1975 by the city of Winterthur.

The tunnel can only be entered on your stomach at first, after a few meters you can crawl through dead wood and water on your knees. You can stand further back, but you have to reckon with 5-10cm of clay water and dripping walls even in good weather. The right tunnel arm ends after a good 20m in a dead end, the left one earlier in deep water.

Here is the entrance to a former tunnel that served the Russian troops in 1799 as an escape tunnel from the French troops. Was forgotten and was rediscovered some time ago.
