Dechenhöhle: The Natural Wonder Among the Sights

The Dechenhöhle is regarded as the absolute number one among the town's sights. This stalactite cave was discovered in 1868 during railway works and is now one of the most beautiful show caves in Germany.

What Makes the Dechenhöhle So Special?

The Dechenhöhle impresses visitors with its unique limestone formations:

• Imposing stalactites and stalagmites in various shapes
• A constant temperature of 10°C all year round
• Professional lighting that sets the formations off to perfection
• Step-free access for wheelchair users
• Open all year round - an experience that does not depend on the weather

The 360-metre guided tour through the cave takes about 30 minutes and offers insights into the history of the Earth that a school textbook can hardly convey. Because of the constant coolness, a light jacket is a good idea even in high summer.

Deutsches Höhlenmuseum

Right next to the Dechenhöhle is the Deutsches Höhlenmuseum, the German Cave Museum, which complements a visit to the town's sights well. Here you can learn everything about speleology, geology and the history of the discovery of the Dechenhöhle.

💡 Tip: Combine your visit to the Dechenhöhle with the cave museum for a complete experience.
