Steigelfadbalm

Steigelfadbalm is a cave on the slopes of Mt. Rigi, in the municipality of Vitznau on Lake Lucerne (canton of Lucerne, Switzerland). It ranks among the most significant archaeological and palaeontological sites in Central Switzerland, and it suits hikers who want an Ice Age story at the end of a mountain walk.

What is Steigelfadbalm?

The cave sits in Nagelfluh, the conglomerate rock that makes up much of Rigi. In Swiss German, a "Balm" is a cave or rock overhang. The site lies at roughly 47.0175° N, 8.4941° E, close to Vitznau, where the Rigi rack railway begins its climb.

Why is it important?

Excavations led by Wilhelm Amrein ran from 1913 to 1937. They yielded more than 3,000 bones and fragments, about 90 percent of them from cave bears. These animals reached around 3.5 m in length, up to 1.75 m at the shoulder and roughly 1,500 kg, and lived between 130,000 and 20,000 years ago. Researchers at the University of Vienna later studied the material, and the site is known in the literature as a fossil-bearing bear cave in the Rigi conglomerate.

The second claim to fame is human presence. Archaeologists found a small quartz point worked on both sides. Similar points belong to the Middle Palaeolithic, roughly 300,000 to 35,000 years ago. The quartz is not local and may come from the Uri Alps. It is the first evidence of Neanderthals in Central Switzerland. Later hunters used the shelter too: a flint knife and a bronze arrowhead point to the Neolithic and the Bronze Age.

How do you get there?

No road or railway reaches the cave. A mountain footpath leads to it, and you can start in Hinterbergen or at the Mittlerschwanden station of the Rigi Bahnen railway. Wear sturdy hiking boots; the slope can be slippery after rain.

What will you see?

An information board by the cave explains the archaeological finds. The cave itself is a natural rock niche, not a developed underground route, so do not expect visitor facilities. The excavated material is not displayed on site; cave bear material is shown in Lucerne, and the Lucerne cantonal archaeology service holds the archaeological collections.

When should you visit?

Late spring to autumn is best, when Rigi paths are dry and free of snow. Plan the walk for daytime, as the cave has no lighting. Rigi Guest Service in Vitznau can advise on the route and current conditions.

Frequently asked questions

Can I visit Steigelfadbalm without a guide? Yes. The cave lies by a publicly accessible mountain path, and an information board stands at the site.

Is the cave linked to Neanderthals? Yes. A quartz point found here is regarded as the first evidence of Neanderthals in Central Switzerland.

Why are there so many bear bones? Cave bears sheltered here during the Ice Age. More than 3,000 bones and fragments survive, mostly from these animals.

Where does the hike start? In Hinterbergen or at the Mittlerschwanden station of the Rigi Bahnen railway.
