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.

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.

Always be prepared for uneven terrain and low light conditions in underground areas.
The Vulkaneifel region offers a variety of outdoor activities. You can find numerous hiking trails, such as the 'View of the Jungferweiher – Ulmener Maar Tunnel loop' or 'Panorama Bench Sarmerzbach – Afelskreuz and Chapel loop'. For cyclists, there are MTB trails like the 'Dronke Tower on the Mäuseberg – View of the Weinfelder Maar loop' and road cycling routes such as the 'Bergkrone Mine Tunnel – Johannes Bridge in Monreal loop'. You can find more details on these activities in the hiking guide, MTB trails guide, and road cycling guide for Hörschhausen.
The caves in this area are often linked to the region's volcanic history and mining. The Bergkrone Mine Tunnel, for example, was a site for barite mining. The broader Vulkaneifel region is known for its volcanic landscapes and maars (volcanic lakes). The Tunnel in the Natur- und Geopark Vulkaneifel is a natural formation within this unique geological setting.
Visitors appreciate the historical insights and the well-preserved nature of these sites. For instance, the Julius-Stollen Slate Mine is described as a 'beautiful, well-kept area' with 'very informative information on signs and slates,' offering 'a lot to discover and marvel at.' The Tunnel in the Natur- und Geopark Vulkaneifel is highlighted as a 'great experience to walk through the tunnel.'
While Hörschhausen itself is more known for its volcanic landscapes and maars, the broader Eifel region does feature significant natural caves. However, the specific highlights around Hörschhausen tend to be historical mine tunnels or man-made structures, such as the Tunnel in the Natur- und Geopark Vulkaneifel, which is a natural monument.
The historical mine tunnels and the natural tunnel can generally be visited year-round, though accessibility might vary with weather conditions. For outdoor activities like hiking or cycling near the caves, spring to autumn offers the most pleasant weather. Some highlights, like the Matthias-Josef Stollen Slate Mine, are noted as 'worth a trip in every season'.
When exploring caves or mine tunnels, it's advisable to wear sturdy, closed-toe shoes with good grip, as surfaces can be uneven or damp. Dress in layers, as temperatures underground can be cooler than outside. A headlamp or flashlight is also recommended, even for well-lit areas, to fully appreciate the details and ensure safety.
The listed highlights, such as the Bergkrone Mine Tunnel and the Juliusstollen, offer unique historical insights into the region's mining heritage. While not 'hidden' in the sense of being unknown, they provide a less conventional caving experience focused on industrial history rather than vast natural caverns, often making them less crowded than major tourist attractions.
