1 million years of geology. Worth putting your bike aside for a moment.

It's called the Ulmen Maar Tunnel and connects the Jungferweiher pond and the Ulmen Maar. The tunnel is finished and has been open to the public since April 25, 2023. It's turned out simply fantastic. A visit is definitely worthwhile. It's open in the summer months from 6 a.m. to 8 p.m. In winter, it's also open during the day. The circular and hiking trail around the Jungferweiher pond and the Ulmen Maar is wheelchair accessible. Cycling through the tunnel is prohibited, as the tunnel is only 70 centimeters wide at its narrowest point. You don't need to be claustrophobic. A visit to the Ulmen Castle ruins, with its fantastic view over the town of Ulmen and the Ulmen Maar, is also highly recommended.

The tunnel is popularly known as the Roman tunnel. However, research by the University of Trier has shown that the tunnel is younger and "almost certainly" dates back to the High Middle Ages, according to a university publication. It was likely created during one of the expansion phases of Ulmen Castle. There is a second, similar tunnel near the castle.
