Genoveva Cave

Highlight • Cave

When you look at the Genoveva Cave, you can easily imagine how people used to seek shelter there. In the ARD fairy tale adaptation of Rumpelstiltskin, the Genoveva Cave was one of the filming locations, along with Bürresheim Castle. Above the Genoveva Cave, there is a small viewing platform. You have a beautiful view of Lake Laach.

The Sandkaul near Ettringen in the Volcanic Eifel.🖤
This former volcanic rock mining area is located on the edge of the Hochstein volcano, north of Ettringen on the L 82 highway, about 500 meters past the end of the village.🖤
Sad background:
🪖During World War II, the Ettringen caves were drilled into the rock...to protect against attacks🧨...

In addition to the official trass caves, there are also the low cave shafts. But these are really low and dark, so a flashlight is a must. In spring 2020 we were able to visit the corridors, but in June 2020 the entrance was blocked by a fallen tree.

Anyone who thinks that an approx. 1m hole in the slate rock (of which there are some on the route of the dream path "Nette-Schieferpfad") is a highlight worth seeing, the detour will be worthwhile for you - but really only for you ...

July 30, 2025, Trasshöhlen im Brohltal – Tiefe Höhlengänge

The Trass Caves in the Brohl Valley are deep, branching cave passages made of volcanic trass rock – formed around 13,000 years ago by the eruption of the Laacher See volcano.

The small cave was once part of a mine, used during the First World War due to a shortage of raw materials. Today, the entrance is a mysterious spot at the edge of the hiking trail, surrounded by trass rocks and jungle-like vegetation. ⚠️ Caution: The cave is not accessible – there is a risk of collapse.

On the 🧡Dream Trail, dotted with many highlights, this is a real outdoor highlight, practically an adventure playground for adults: Impressive large trass caves...- Endless photo opportunities beckon here📸🎨🖌. Pleasantly cool & refreshing, especially in the warmer summer season🌞🌡. There are also numerous free parking spaces, some of them shaded, next to the large 🚂viaduct🌞🌡

The freely accessible trass caves in the Brohltal are located below Bad Tönisstein on the Brohltalstraße (Federal Highway 412) at the height of the "Jägerheim" inn. The caves were formerly used by the trass millers: they had the raw material, the freshly cut trass "arks", dried there.[1] There are parking spaces for cars near the caves. The Kell Cave and Gorge Trail, a circular hiking trail, leads past the trass caves. Source: https://www.aw-wiki.de/index.php/Trassh%C3%B6hlen_im_Brohltal

It is hard to imagine the working conditions of the miners who went into the mountain to laboriously mine the slate.

Frequently Asked Questions

What makes the caves in Landkreis Mayen-Koblenz unique?

The caves in Landkreis Mayen-Koblenz are primarily shaped by the region's volcanic history and extensive historical mining activities. You'll find a mix of man-made underground labyrinths, such as the vast Trass Caves Brohltal and the Sandkaul Caves near Ettringen, alongside sites like the Mendig Lava Cellars and the Roman Mine Meurin, which offer deep insights into geology, ancient engineering, and industrial heritage.

Are there natural caves or are they mostly man-made?

Many of the prominent 'caves' in the region are actually extensive underground structures created by human activity, primarily basalt and tuff mining. Examples include the Mendig Lava Cellars, the Millstone Caves, and the Roman Mine Meurin. However, natural formations and rock shelters, like the Genoveva Cave, also exist, often with historical significance.

What historical significance do the underground sites in Mayen-Koblenz have?

The underground sites hold significant historical value. The Roman Mine Meurin, for instance, is the largest underground tuff mining area from Roman times north of the Alps.

Some, like the Sieben Stuben Lava Caves, even served as air raid shelters during World War II.

Can I visit any ice caves in the wider Vulkaneifel region?

Yes, while not strictly within Landkreis Mayen-Koblenz, the Birresborn Ice Caves in the wider Vulkaneifel area are a notable example. These former basalt millstone mines are famous for maintaining consistently cold temperatures, often below 7 degrees Celsius, allowing icicles to persist well into warmer months.

What should I wear or bring when visiting the caves?

For many underground explorations, especially in less developed sites like the Birresborn Ice Caves or some millstone caves, sturdy shoes are highly recommended. A torch or headlamp is often essential due to the darkness, and a helmet might be advisable for certain areas. Even in summer, temperatures underground can be cool, so a light jacket is a good idea.

When is the best time to visit the caves in the region?

Many caves and underground attractions, especially those integrated into the Volcano Park, are accessible year-round. However, some sites, like the Birresborn Ice Caves, are typically open from April to October to protect bat populations during their winter hibernation. It's always a good idea to check specific opening times for the site you plan to visit.
