"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.

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