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.

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.

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.

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

A photogenic relic of an old mill is this water wheel on a tributary of the Nette.

It's a shame that the Sandkaul Caves are used by some people as a dumping ground for their garbage.

These sites showcase the region's volcanic history and industrial heritage.

Are there any family-friendly cave experiences near Nickenich?

Yes, several cave-like attractions are suitable for families. The Trass Caves Brohltal are known for their mighty rock faces and a 'jungle atmosphere,' with an visible exit that can be reassuring for those with claustrophobia. The Sandkaul Caves near Ettringen and the Sieben Stuben Lava Caves also offer engaging exploration for all ages. Additionally, the Mendig Lava Cellars provide guided tours that are educational and accessible, with an elevator available.

What is the historical significance of the caves in this region?

The caves around Nickenich are rich in history. The Mendig Lava Cellars, for instance, are an extensive network of man-made tunnels created by basalt mining dating back to the late Middle Ages. These cellars were later used by breweries for beer storage due to their consistently cool temperatures. Other sites like the Genoveva Cave and the Sandkaul Caves near Ettringen also have historical ties, with the latter being drilled for protection during World War II.

What are the Mendig Lava Cellars and how can I visit them?

The Mendig Lava Cellars are a unique network of man-made underground tunnels and chambers, created by the mining of basalt lava. They are located 32 meters below the town of Mendig and were historically used for basalt mining and beer storage. Access is only possible through guided tours organized by the nearby Lava Dome volcanic museum. An elevator is available for easier access. You can find more information about the museum and tours at museumsportal-rlp.de.

Are there any natural caves or lava tubes to explore?

While the region is volcanically active, most 'caves' are man-made or significantly altered by human activity. The Mendig Lava Cellars are formed within cooled lava flows, offering a direct experience of the region's volcanic geology. The Sieben Stuben Lava Caves are also situated in volcanic rock, providing a glimpse into the natural formations shaped by ancient eruptions.

What should I wear or bring when visiting the caves?

The Mendig Lava Cellars maintain a consistent cool temperature (6-9 degrees Celsius) and a damp atmosphere year-round, so bringing a jacket or warm layers is advisable. For exploring sites like the Trass Caves in the Brohl Valley – Deep Cave Passages or the Sieben Stuben Lava Caves, a headlamp or flashlight is highly recommended due to the low light conditions in some sections.

Can I bring my dog to the caves or nearby trails?

Specific dog policies for individual cave sites can vary. For outdoor activities, many trails around the Laacher See and in the Volcanic Eifel region are dog-friendly. It's always best to check specific regulations for each attraction or trail before your visit. For example, the Trass Caves Brohltal are generally accessible with dogs, but always keep them on a leash.

The Mendig Lava Cellars maintain a constant cool temperature year-round, making them a refreshing escape during hot summer months and a unique experience in cooler seasons. For other cave-like attractions and outdoor trails, spring and autumn often offer pleasant weather for exploration.
