Discover the Namedyer Werth nature reserve

Dividing line

The Geysir Andernach is located on the Namedyer Werth. This is a forested peninsula in the Rhine, west of Andernach. In order to extract the carbon dioxide produced by volcanic processes deep below the peninsula, a 343-metre-deep hole was drilled there in 1903. The extractedCO2 was to be used to produce a mineral water, the "Namedyer Sprudel".

Through the borehole, the gas dissolved in the groundwater suddenly had a direct path to the surface. It escaped and shot out of the borehole together with the groundwater. This is how the Andernach geyser awoke for the first time. At that time, the fountain was still almost 40 metres high, 20 metres smaller than today. The phenomenon was called "Namedyer Sprudel", just like the bottled mineral water.

But the Andernach geyser was not always the attraction it is today. It was only opened up to tourists in 2006, and two years later it was entered in the Guinness Book of World Records as the highest cold-water geyser on the planet. Since then, thousands of visitors have come to see it every year. The geyser erupts every two hours. An eruption lasts about eight minutes.

The Namedyer Werth is a nature reserve. Here you will discover not only undisturbed nature, but also rare plants and even endangered animal species. Nine different species of bats alone call the Namedyer Werth home.

Rare or endangered bird species also inhabit the nature reserve. It serves as a breeding ground for the black kite and as a habitat for the oriole and the colourful kingfisher. The alluvial forest and the Old Rhine arm are also worth protecting.

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.
