From large stone blocks, a barrier has been erected around the area - for good reason - signs indicate a prohibition of entry, which should absolutely be observed for your own safety. Partially, fossil inclusions are recognizable in the stone blocks from the hiking trail.

On the way to the Dreimühlen waterfall, which is well-known beyond the Vulkaneifel region and a popular excursion destination, the hiker sees the limestone rock formation towering over the water a little beforehand. It's a bit reminiscent of the Swabian Jura, as someone told me on the way today.

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.

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.
