Ulmener Maar Tunnel

Highlight • Structure

The Ulmener Maarstollen was completed in 2023 and connects the Jungferweiher with the Ulmener Maar. Hopefully it stays as clean and beautiful as it was when I visited yesterday.

Juliusstollen and Kaulenmännchen Sculpture

Highlight • Historical Site

A few meters you can go here in the tunnels before an iron door blocks the further passage. With a good flashlight you illuminate the interior and will be amazed …

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

The Ulmener Maar tunnel connects the Ulmener Maar with the Jungferweiher Maar and is 120 meters long and 70 cm wide at its narrowest point. Different rock layers from the volcanic history can be seen. Display boards and paintings on the tunnel make the history very interesting. The tunnel was used to channel water from the two maars into the Ulmener Bach to the mills. Next to the tunnel, two drains and bulkheads are used to regulate the water level.

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.
