Feldhof Cave

Highlight • Cave

The Feldhof Cave awaits you after a bend. It is very large and you should take a flashlight with you to explore so that you don't end up standing in the dark. A very interesting historical place.

Felsenmeer (Hemer)

Highlight • Natural Monument

The Felsenmeer in the Sauerland of Hemer is a protected area since 1968, whose rugged subsoil originates from the Tertiary. This area of ​​the sea of ​​rocks is about 600 meters long, 200 meters wide and is 45 meters above the valley floor. It is divided into three areas, the Big Rock Sea in the northwest, the Small Rock Sea in the south and the paradise in the southeast.
The nearby Heinrichshöhle is a stalactite cave, which is open to visitors.

The Felsenmeer itself is freely accessible around the clock. Leaving the marked trails is prohibited and very dangerous, as crevices are often hidden under leaves and branches. This has already resulted in several deaths.

The Balver Kulturhöhle impresses right from the first step: a gigantic natural dome, up to eleven meters high, which has been used since the Old Stone Age and is today considered an extraordinary event venue. Where Neanderthals and cave bears once found shelter, you can now experience concerts, theater, and the traditional Schützenfest (marksmen's festival) in an acoustics that is second to none. The cave is only accessible as part of events or guided tours, but a glance at the mighty entrance is enough to reveal why it fascinates as Europe's largest open hall cave. https://www.sauerland.com/de/neusta-pois/balver-hoehle-europas-groesste-kulturhoehle

The Balver Cave is the largest open cultural cave in Europe with an entrance portal that is 11 meters high and 18 meters wide. In the huge hall, which is almost 90 meters deep and splits into two arms after 54 meters, around 2,000 people can celebrate or experience the unique acoustics and atmosphere at concerts. Caves only exist in limestone. This grew from dead corals in a warm sea around 360 million years ago. The enormous forces of the earth's interior fold, raise and lower the originally crack-free mass limestone. Penetrating water dissolves the lime, widens the cracks into crevices and cavities - this is how our cave was formed over tens of millions of years. During the ice ages 100,000 to 20,000 years ago, mud was deposited in the Balver Cave. The cave clay filled the cave almost to the ceiling. The farmers recognized the high fertilizer value of the phosphate-containing clay and brought it to their fields. This is how the impressive cave space was uncovered - a rock dome. During later excavations, skeletons of local animals, such as mammoths and cave bears, and around 40,000 artifacts were found.
