Klutert Cave

Klutert Cave, also known as the Kluterthöhle, is Germany's longest cave, stretching over 5 kilometers (3 miles). The cave has approximately 300 courses and is lined with a series of underground streams, lakes, and fossils that have been present for the last 350 billion years. The cave is an adventure land with fascinating animals and a fascinating history; it was used as a raid shelter during WWII. Kluterthöhle also provides Speleotherapy to patients suffering from asthma, bronchitis, hayfever, and a variety of allergies and skin disorders.

The Kluterhöhle cave system features underground lakes, strange rock formations, and a maze of 380 tunnels. The fossilized remains of shells, corals, and sponges cover the rocky walls and bear witness to a time when the region near Dortmund was covered by a reef. Themed tours focus on different aspects of the cave. The 'XX-Treme tour,' which takes visitors through narrow passageways and pitch-black caverns, is recommended for thrill-seekers.
