Just above Überkingen, at the rim of the Swabian Jura plateau, is a rock called Kahlenstein (bald rock). This rock provides a beautiful view on Überkingen and the Bluna plant (Bluna is a famous German beverage, which is made here). The rock is formed by the hard limestones of the Malm. Locally this rock is called Weißer Jura (White Jurassic) because of its white colour. Its layers are locally numbered with greek letters, and this layer is numbered δ.
The Kahlensteinhöhle is named after the Kahlenstein, as it is located on top of the rock, only a few meters from the outlook. It is the biggest of more than 50 small caves know in this rock. The cave belongs to the city limits of two towns, Bad Überkingen and Geislingen. At the entrance of the cave a nice terrace with an outlook was built.
The entrance is 1.5 meters wide and 2.2 meters high, and closed by an iron bar gate. From here a passage of about the same size leads horizontally into the rock. Then the visitor reaches a small chamber, only a bit bigger than the passage. The walls are stained black by torches and fireplaces. Now the passage continues to the northeast. It splits in to two passages, which join again after only three meters.
The cave is known for hundreds of years. Unfortunately this led to numerous destruction, people vandalized the cave and made fires inside. In the year 1892 the local tourist club developed the cave with trails and opened it as a show cave the same year. The tours were continued until around 1900. It seems the cave was never closed, so people were able the cave without a tour, and the destruction continued. As it is located at an outlook many walkers came along and visited the cave.
In 1971, the Arbeitsgemeinschaft der Höhlenfreunde Kahlenstein e.V. Geislingen was founded - later to become the Kahlensteiner Höhlenverein (Kahlenstein Caving Club). They took over the care and protection of the cave and closed it with a massive gate for the first time in 1972. For a few decades, it was opened as a show cave at weekends, then only by appointment for groups. In the 1990s, however, the ceiling became so unstable that guided tours could no longer be made for safety reasons. The cave is very close to the earth's surface and the ceiling is becoming increasingly unstable due to weathering. It is therefore no longer possible to visit the cave, even though various websites claim otherwise. Those pages are outdated.
