At the beginning of the 20th century, the village priest bred trout in the maar, which was around 100,000 years old. In the 1920s the water was drained and its quickly overgrown, fertile ground was used as a viewing area. 80 years later, scientists proved that this was a silted maar. During a core drilling, 23 m of animals found tuff remains from the Laacher See eruption 13,000 years ago. In addition, the funnel lies on a geological fault line that runs from northwest to southeast. The renatured maar is around 120 meters in diameter and offers a biotope for numerous birds. When the maar was revived from 2007, the Oosbach was dammed. Source: 111 places in the Eifel that you have to see Further information: https://de.wikipedia.org/wiki/Eichholzmaar

Super nice little nature reserve with many bird observation posts. Many paths around the Maar and a small parking lot are the ideal starting point for a hike.

Magnificent rock formations to marvel at. Partly supported with thick concrete pillars so they don't fall into the city.

Well accessible cave. It is very good to see how the millstones were worked out. A good headlamp is recommended so that your hands are free to take pictures. I personally found the cell phone camera too dark

The Gerolsteiner Dolomites are incredibly beautiful and definitely worth a visit. They bear their name with full justification.

"With an area of approx. 102 hectares, the area around the Gerolsteiner Dolomites has been a nature reserve since 1990. + occurring animal species: bat + occurring plant species: juniper, orchids, character plants calcareous grassland, grove rush-beech forest, woodruff-beech forest, orchid-limestone-beech forest Around 380 million years ago there was a warm, subtropical shallow sea here, in which mighty reefs of stromatopores - relatives of sponges - and corals formed. After the dolomitization, sinking and folding of the rocks, the Devonian deposits were lifted out again. Today's Gerolsteiner Dolomites were formed, which rise steeply above the Kylltal north of the center of Gerolstein. The rocks "Hustley", "Munterley", "Drohende Ley", "Große Kanzel" and "Auberg" characterize the cityscape from afar and form the landmark of Gerolstein. The most famous summit of the Gerolsteiner Dolomites is the "Munterley" - with a height of 482 meters - and offers a breathtaking view over Gerolstein, the Kylltal and far into the Vulkaneifel. Stone Age people, who settled here 30,000 years ago, obviously enjoyed this view, as evidenced by stone tools and bones found at the nearby Buchenloch Cave. Visiting the Gerolsteiner Dolomites can be perfectly combined with hiking the Felsenpfad - the northern part of the "Gerolsteiner Dolomiten Acht". The almost eight-kilometer round tour offers many magical places and geological traces." https://www.eifel.info/a-gerolsteiner-dolomites

I found our short hike through the Gerolstein Dolomites interesting and varied. If you park near the Kasselburg, you save a bit of the ascent, which may be good for a hike with children.
