ケルバーグの天然記念物・トップ20

The karstified limestone cliffs are the first highlight on the path from the parking lot to the waterfall. Here, the stream has carved its way through the limestone, creating the rock face. The limestone originated as a deposit of dead marine organisms on the seabed of a shallow ocean that covered this area millions of years ago. Later, the ground was uplifted by tectonic processes. Limestone reacts with acid and is therefore dissolved by rainwater and surface water, which is slightly carbonated due to the CO2 in the air. This process creates weathered formations and caves. The formation of the Dreimühlen Waterfall is also related to this process.

Beautiful rock face to see.

Imposing limestone wall behind the Nohner Mill

The Ulmen Maar lies 420 meters above sea level today, covers an area of 5.5 hectares, and is 36 meters deep. The bubbles at the maar's edge demonstrate that volcanism is still active. They bear witness to a turbulent past—but rest assured, there's no eruption in sight! A wall of various rocks and ash, up to 20 meters thick, surrounds the cone. For those interested, these testimonies to this explosive past are beautifully displayed in St. Matthias Church. This unique wall, with its different colored layers and rounded inclusions, is worth seeing for more than just geologists. The slopes of the maar basin are covered with a beautiful forest, which can be explored on a circular walk. A detour to the medieval castle ruins, from which the Crusaders once launched their campaigns, is recommended. The view from the crater rim over the maar and the Eifel beyond will take your breath away. Whether after a sweaty hike or a long drive, the blue of the Ulmer Eifel lake is all too tempting in summer. However, bathing in the maar is prohibited because it is designated as a nature and water protection area.

The so-called Dreimühlen waterfall is also known as the Nohn waterfall. The name Nohn waterfall comes from the waterfall's proximity to the town of Nohn. The houses on the outskirts of Nohn are only a few hundred meters above the waterfall. Most people talk about the Dreimühlen waterfall, however. The name Dreimühlen comes from a former castle called Dreimühlen. Today, however, only the remains of the walls are said to remain. We looked for the former castle on our trip, but couldn't find anything of it. The waterfall in the Eifel is located between the towns of Üxheim, Kerpen and Nohn. Although the other large towns in the Eifel are not located here, many visitors come here. Some of them travel especially to visit the waterfall. The Dreimühlen waterfall is one of the most visited Eifel attractions. Almost every holidaymaker in the area comes to the waterfall at least once during their Eifel vacation. In addition, many day tourists travel from outside, making it the most visited waterfall in the Eifel. They all want to see the unique natural wonder.

Nice entrance to hiking tours to the waterfall

The Ulmener Maar is small but beautiful. Located in the middle of the Eifel and in the middle of the city, it is a wonderful destination. You can easily combine a walk around the maar with a walk around the neighboring Jungferweiher. Both have recently been connected by the Ulmener Maar tunnel, which runs under the A 48 motorway.
