In summer it is difficult to identify the 'driveway' in the uppermost part of a freshly mown meadow. After a few meters along the edge of the forest, however, the trail increasingly peels out of the green. The trail can actually be 'speeded', with a very steep end.

The Huppenweiher pond has an interesting history. It is not actually natural, but rather arose from the mining pit where the so-called Huppererde was mined from the 17th century onwards. Huppererde is a white fireproof clay that was suitable as a melting pot and was used in furnace construction. At that time, most of the earth was exported to France, Germany and Genoa/Venice, where chimney stones were made to line fireboxes. These were used in blast furnaces, glass furnaces and cannon foundries, for example. The mining continued until the end of the 1940s.
