The "Slate Cave" as an atmospheric world of knowledge

You are now at a depth of 500 metres. As soon as you step out of the mine lift after your exciting descent, you can't help but be amazed. In front of you is the slate cave, elaborately designed by a group of freelance artists and stage designers. The large, dark vault looks so realistic that you have the feeling it is real.

Huge slate pillars seem just able to support the massive ceiling. Above them lie thousands of tonnes of rock and earth. Light installations strongly set the stage for the artificial stone formations. Let the fascinating atmosphere take effect on you.

The slate cave is one of the highlights of your visit to the museum. But it is not only visually impressive. The multimedia exhibits also arouse your interest. At numerous vertical water columns you can test for yourself howCO2 dissolves in water. You are welcome to try it out!

Nice excursion with a nice explanation. We had a very nice trip to the geyser. The geyser was very impressive to see. Special thanks to the staff, who were very friendly and helpful and made the trip possible for us (assistance due to walking difficulties).

Highly recommended! An interactive tour explains the formation of a geyser in a fun way. The absolute highlight is the boat trip to the geyser, where you can see the natural spectacle live.

It is a wonderful hands-on museum. Even small children can try out and explore here. Older children and adults can learn lots of new things. The accompanying boat trip is a highlight. The geyser experience at the end is just great. The staff are polite and friendly. Very helpful. The museum is also suitable for baby carriages. The parking spaces are scarce, but with a bit of luck you ...

The boat trip to the geyser was informative and we were told about the formation of the geyser. There was a lot of staff on site who were keen to pass on their knowledge. A conversation with the staff was very helpful and informative.
