When the Andernach geyser awoke

In the "borehole" you follow the geyser water to the eruption

After your stay in the Slate Cave you enter the next visually impressive area of the museum: the borehole. Watch out! A huge, two-metre drilling head seems to be breaking through the rock face right now. Fortunately, it is part of another breathtaking scenery. But why a borehole? And what does it have to do with the Andernach geyser?

In order to provide the carbon dioxide with a way out of the depths, a hole was drilled in the Namedyer Werth Peninsula. Normally, theCO2 would have slowly risen to the surface through small gaps and pores in the earth. But now there was a much faster way up. Now the highly pressurisedCO2 could escape all at once, and it did so with tremendous force - the Andernach geyser erupted for the first time. At that time, by the way, it was still called "Namedyer Sprudel".

But similar to the slate cave, here you will not only be amazed by the elaborate design. Various Exhibits are waiting to be tried out and examined by you. With hand drills, you find out for yourself how different types of rock behave, what density and degree of hardness they have. But your geyser expedition is not over yet, it continues!

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 thus made the excursion possible for us (help due to walking disability).

Absolutely recommendable! In an interactive tour, you can learn about the formation of a geyser in a playful way. The absolute highlight is the boat trip to the geyser, where you can see the natural spectacle live.
