コップの湖・トップ7

Lake Müllenborn – often called Müllenborner Weiher – is picturesquely located in the Müllenborn district north of Gerolstein and is a real insider tip for Komoot tours. The idyllic expanse of water, surrounded by cool forests, invites you to stroll, picnic, and enjoy mindful moments by the water. A beautiful, approximately 6km circular trail leads around the lake, past the historic millstone ruins and along the Oosbach stream – ideal for quiet explorations away from the hustle and bustle. Around Müllenborn, you'll learn firsthand about the region's volcanic history: Oversized basalt blocks from the former Rother Kopf dominate the forest landscape, and you'll repeatedly encounter springs, small bridges, and the remains of old mills – hence the name "Mühlenborn" (Millsborn). The village itself, with its chapel and baroque houses on the shore, provides a charming, historic setting for the lake. The lake is not open for swimming, but in summer, you'll often find locals cooling off or fishing here; provided you have a valid license. A visit to the Müllenborn Lake Festival in July is particularly atmospheric – with brass bands, a festival tent, and a convivial village atmosphere. Just a few hundred meters away is the comfortable Landhaus Müllenborn, a 4-star country hotel with a spa, sauna, and sauna terrace – perfect for relaxing after the circular hike. The Eifelsteig trail runs nearby, and cyclists can also find connections to regional routes such as the Eifel-Ardennes Cycle Route.

The view is just as good a little further along the Maar bank.

From here you have a beautiful view over the idyllic Eichholzmaar.

Simply climb up the few steps and enjoy the beautiful view of the Eichholzmaar.

The Eichholzmaar is one of the smaller maars. This maar is round and has a diameter of about 120 m. Its maximum depth is 3 m. It was drained at the beginning of the last century and in 2007/2008 it was renaturalized and filled with water. Now water birds and reptiles live on this maar again.

On the meadow path you come across the small pond. When we were there, there were lots of tadpoles swimming in it.

According to the book "111 places in the Eifel that you have to see", the Eifel Association documents from here which birds visit the biotope - including great shrikes, red-backed shrikes and turtle doves. We were able to observe a cormorant here.

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
