Caves in the Harz

In the Harz, you can explore caves where rock formations from millions of years ago have been preserved. Stalactites and stalagmites show how water and limestone have created new structures over long periods of time. On a guided tour, you’ll find out how these caves were formed and which geological processes continue to shape them today.
The paths lead you deep into the underworld of the mountains. Light, temperature and silence are quite different from the world above ground. This gives you a direct impression of the interplay between stone, water and time.

These tours are aimed at people who want to observe natural phenomena and learn more about the history of the Harz.

The compiled overview shows known and accessible caves in the Harz region. It’s aimed at everyone who’s interested in nature, geology, or former mining. You can use the individual entries to check information about location, opening hours, and special features of each cave.
Be aware that in some caves sturdy footwear and a jacket are useful – the temperatures usually remain cool all year round. Some places are only open seasonally or can be visited as part of guided tours.
The list is especially helpful when you’re planning your stay or looking for a weather‑independent destination. This way, you can quickly find places where you can experience the Harz from a completely different perspective – underground.
