"The Hole" is an experience even without children. With children it is a must. It is pitch black at times, but with a "cell phone flashlight" it is possible in a pinch.

"The Hole" is definitely worth a visit, even if you don't have children with you. A must with children.

It is a large cave or chamber in the loess in a loess hollow way. These hollow ways in the thick loess layers in the Kaiserstuhl were created by constant use as a path (especially with heavy carts). The resulting depressions were made worse by erosion in wind and weather (especially rain). In many places, holes were dug into the loess walls for various purposes (storage of material, "cooling chamber"). Loess is a calcareous, silty sediment, i.e. rock powder with lime components. The lime structure gives loess a high level of stability. This means that stable caves can easily be dug into them. Here, two such holes are connected by a tunnel that can also be easily walked through.

The Kammergraben is the path that leads from Bleichheim up to the castle meadow and on to Kürnberg Castle. Halfway up to the castle meadow there is a tunnel mouth in the hillside in the Kammergraben in the Gewann Bergmannsloch. If you climb this slope to the west, after a few meters you will find a so-called pinge in the forest. A pinge is a funnel-shaped depression in the terrain that was created by mining operations, where the vertical entrances into the mine tunnels collapsed and the soil above slipped. The chamber moat was once owned by the Meiger von Kürnberg, vassals of the Lords of Üsenberg and bailiffs of Kürnberg Castle. They had probably already been mining here in the late Middle Ages. Further Pingen are located northwest below Kürnberg Castle on the Ölberg and along the Kammergraben. The ore deposits here were very sparse. Brown iron stone, manganese iron ore and galena were primarily mined here. But there are also numerous references to mining activities on the Kirnhalden, east of the castle on the Erzbuck.

The Lössholweg trail is worth a hike. What is particularly special is that there is a cave or tunnel in the seemingly loose loess.
