Unfortunately, the path there is completely overgrown and impassable. As of June 25, the descent isn't worth it.

The Nerother Kopf is an extinct volcano of recent date. It was formed about 15,000 years ago when the earth broke up here and glowing magma welled up from the depths of the earth. At that time, a fracture zone formed in the earth rock, which formed the origin of the volcanic chain "West Eifel". https://www.neroth.de/tourismus/nerother-kopf

The Millstone Cave is located at the summit of the Neroth Head, a wooded hill of volcanic origin east of Neroth. The entrance is just below the Freudenkoppe castle ruins at an altitude of about 640 m and can be reached via a hiking trail. The cave is 18 meters deep and its vault up to 10 meters high. It is walkable, but unlit (torch required). Wikipedia

Millstones were mined in the 18 meter deep cave at the top of the Nerother Kopf until the 18th century. The lava stone was not only mined for the production of millstones, but was also used to build the immediately adjacent Freudenkoppe Castle.

A grotto in honor of the Holy Mother of God has been built from lava at the church entrance, with an altar table in the largest grotto.

Iron ore search tunnel in the Grundwies district of Niederscheidweiler. When the last ironworks in Eisenschmitter closed in 1868, the ore search continued. Around 1890, a 35m long walk-in tunnel was driven horizontally into the mountain here in the Alfbachtal near Grundwies. Also in the valley of the Sammetbach, in front of the confluence with the Alf, an ore exploration tunnel about 10 meters deep from this period has been preserved and other tunnels that have been forgotten are located on the south side of the Manderscheider saddle and the north side of the Moselle basin. According to Section 39 of the Federal Nature Conservation Act, the bat protection period begins on October 1st and ends on March 31st. During this period, bats are legally prohibited from entering caves, grottos, bunkers, tunnels and other potential hibernation dwellings. Source: Kulturdb.de

Former mine Goldglück Niederstadtfeld, Niederstadtfeld municipality description [...] The mine that was operated in the previous century should not go unmentioned. The field names "Am Bleiofen" and "An der Bleireinigung" are still reminiscent of this former mine. In 1858 it employed 12 to 15 miners who came from Niederstadtfeld and Üdersdorf. The mine, which was located on a mountain east of the valley of the Kleine Kyll in the direction of Schutz, was probably of Roman origin, because there was already a tunnel when the work in the mine began. A tunnel still exists today, but the three shafts on the top of the Bleiberg were filled in for safety reasons after the Second World War. In the mine, which was called "Goldglück", silver, lead and copper were extracted. The ore, which was melted into blocks, was transported to the large works in Mechernich and Bleialf with the help of ox carts. There is still a registered water right to discharge the waste water from the mine into the "Kerlsbach", which flows into the Kleine Kyll. Work in the mine was temporarily suspended, for example in the years 1858 to 1907, for reasons that were not known. After a long interruption, production in the mine was resumed in 1907 and again it was Niederstadtfelder and Üdersdorfer who found work there. However, in order to get to the ore in the deeper regions, a transverse shaft had to be built from the deep "guy". In 1915 the work in the mine "Goldglück" was finally stopped due to the strong effects of the war. During the war, some families from Niederstadtfeld still used these tunnels as bunkers.

The Vulkaneifel region offers a diverse range of subterranean sites. You can explore natural caves formed by geological processes, historical mining tunnels for lead and iron, and artificial millstone quarries that have become cave systems. These include sites like the natural Buchenloch Cave, the historical Goldglück Former Lead Mine, and the unique millstone caves.
Yes, the region features several 'ice caves' such as the Millstone Cave at Rother Kopf and the Birresborn Ice Caves. These are special because cold winter air gets trapped inside, maintaining consistently low temperatures (often between -1°C and +6°C) that allow ice and icicles to persist well into the summer months. They were historically used as natural refrigerators and are now important bat habitats.
Several caves provide a glimpse into the Vulkaneifel's past. The Buchenloch Cave in Gerolstein shows evidence of early human habitation, including Neanderthals, dating back 30,000 years. The Millstone Cave at Nerother Kopf and the Millstone Cave at Rother Kopf showcase historical craftsmanship from millstone quarrying. The Goldglück Former Lead Mine and the Iron Ore Prospecting Tunnel Grundwies highlight the region's mining heritage.
For most cave explorations in the Vulkaneifel, it's highly recommended to bring a flashlight or headlamp, as many are unlit. Sturdy footwear is essential for uneven terrain, and warm clothing is advisable, especially for the 'ice caves' where temperatures remain cool even in summer. For some sites like the Birresborn Ice Caves, a helmet might also be recommended.
While specific 'family-friendly tours' aren't detailed for all caves, many are accessible for families who are prepared. Natural caves like Buchenloch Cave and the artificial millstone caves offer engaging experiences for children interested in history and geology. Always check specific accessibility for younger children, as some paths might be uneven or require ladders.
Many caves, especially the natural ones and millstone quarries, are accessible year-round. However, for nature conservation reasons, some caves like the Birresborn Ice Caves are typically open from April 15th to October 15th to protect hibernating bats. The bat protection period, usually from October 1st to March 31st, prohibits entry to certain tunnels and grottos. Visiting during warmer months allows for comfortable exploration of the cooler 'ice caves'.
The Vulkaneifel region offers excellent opportunities for outdoor activities. You can find numerous cycling routes, including easy and moderate options like the 'Cycle path on a railroad line – Sangweiher Bird Sanctuary loop' or more challenging rides. There are also many hiking trails, such as the 'Holzmaar Viewing Platform – View of the Holzmaar loop' or the 'Mürmes Nature Reserve – Mürmes Bog loop'. For more options, explore the cycling, hiking, and road cycling guides around Udler.
Yes, several caves serve as important habitats for wildlife. The Buchenloch Cave, for instance, is a known hibernation spot for bats. The Birresborn Ice Caves are particularly significant as winter quarters for numerous bat species, which is why they have seasonal closures to protect these animals.
The caves in the Vulkaneifel region are strongly influenced by its volcanic past. You'll find formations carved out by groundwater in natural caves, and the artificial millstone caves are often excavated from porous volcanic rock like lava boards, which was ideal for millstone production. The region's volcanic activity has shaped the landscape, creating unique subterranean environments.
Visitors appreciate the unique combination of natural beauty and historical significance. The impressive geological formations, the tangible evidence of historical craftsmanship in the millstone caves, and the insights into prehistoric human history at sites like Buchenloch Cave are frequently highlighted. The cool temperatures in the 'ice caves' are also a popular feature, especially during warmer months.
The Mauseloch Cave is a natural monument, approximately 10 meters long. However, visitors have noted that the path leading to it can sometimes be completely overgrown and impassable, making access challenging. It's advisable to check recent visitor tips or local conditions before planning a visit.
Yes, the Millstone Cave at Nerother Kopf is located just below the Freudenkoppe castle ruins, adding a layer of historical and cultural interest to your visit. The Nerother Kopf itself is an extinct volcanic cinder cone, and the cave is historically significant as the founding place of the Nerother Wandervogel youth club.
