The name Julius for this adit was chosen in memory of a foreman who worked here for many decades. The entrance to the Julius adit - closed for safety reasons (!) - is located here in direct proximity to a seating area and a memorial stone illustrating the legend of the mythical "Kaulenmännchen".

The region around Retterath, part of the Volcanic Eifel, offers a mix of historical mining tunnels and natural cave formations. You can find former basalt and slate mines, such as the Matthias-Josef Stollen Slate Mine and the Bergkrone Mine Tunnel, which showcase the area's industrial past. There are also natural karst caves like the Buchenlochhöhle and unique 'ice caves' formed in old basalt quarries, such as the Birresborner Eishöhlen and Mühlsteinhöhle.
Yes, the Matthias-Josef Stollen Slate Mine is noted as family-friendly. The Buchenlochhöhle in Gerolstein is also a good hiking destination for families, offering a glimpse into geological and prehistoric history. Always ensure children are supervised, and bring appropriate gear like flashlights and sturdy shoes.
Many caves in the region are best visited during specific seasons. The Birresborner Eishöhlen are accessible from April to October to protect hibernating bats. The Buchenlochhöhle is accessible year-round. For caves known for ice formations, like the Birresborner Eishöhlen and Mühlsteinhöhle, visiting in late spring or early summer might offer the best chance to see ice persist.
It is highly recommended to bring a flashlight or headlamp, as many caves are dark inside. Sturdy, non-slip shoes are essential for navigating uneven terrain. For caves like the Birresborner Eishöhlen and Mühlsteinhöhle, which maintain cool temperatures even in summer, warm clothing is advisable. A helmet might also be useful for low passages.
Absolutely. Many caves in the Volcanic Eifel region are former mining sites, offering a direct connection to historical resource extraction. The Matthias-Josef Stollen Slate Mine and the Bergkrone Mine Tunnel are examples of this. The Mühlsteinhöhle at Rother Kopf showcases medieval millstone quarrying, with unfinished millstones still visible. The Buchenlochhöhle has evidence of Neolithic inhabitants and was used as a refuge during WWII.
The caves are often nestled within scenic landscapes. For example, the Heinzelmännchen Cave offers a great view over the Mimbachtal from nearby loungers. The Rother Kopf, home to the Mühlsteinhöhle, provides fantastic views over the Oosbach valley. The Buchenlochhöhle is within the Gerolstein Dolomites nature reserve, surrounded by beech forests and scenic hiking trails.
Many of the caves in the region, including the Birresborner Eishöhlen and Buchenlochhöhle, serve as important habitats for bats. They use these cool, stable environments for hibernation during winter and as summer hunting pauses. This is why some caves have restricted access during certain months to protect these animals.
Yes, the region offers numerous outdoor activity options. A 5-kilometer Geo-circular trail around Birresborn leads to the Birresborner Eishöhlen. The Buchenlochhöhle is part of scenic hiking trails like the Gerolsteiner Felsenpfad. For cycling enthusiasts, you can find various routes, such as those listed in the MTB Trails around Retterath, Road Cycling Routes around Retterath, and Cycling around Retterath guides, some of which pass by or near cave sites like the Bergkrone Mine Tunnel.
The 'ice caves' like the Birresborner Eishöhlen and Mühlsteinhöhle are unique because they were originally basalt quarries. Their specific structure, with a single opening and downward-sloping floors, traps cold winter air. This creates a microclimate where impressive ice formations can persist well into early summer, even on hot days, with temperatures rarely rising above 7 degrees Celsius.
Access to deeper sections of historical mine tunnels is often restricted for safety and preservation. For example, at the Juliusstollen and Kaulenmännchen Sculpture, only a few meters are accessible before an iron door blocks further passage. The Bergkrone Mine Tunnel entrance is currently closed. Some former slate tunnels are also closed, though visitor mines like one in Bendisberg offer official entry to the underworld.
Yes, several caves are located near or offer access to scenic viewpoints. The Heinzelmännchen Cave has loungers on the slope above it, providing a great view over the Mimbachtal. The Rother Kopf, where the Mühlsteinhöhle is located, offers fantastic views over the Oosbach valley.
The difficulty varies depending on the specific cave. Many are accessible for general exploration, but some may require stooping in low passages or navigating narrow spaces. For instance, the Buchenlochhöhle requires climbing a narrow, steep wooden ladder. Always check specific requirements for each cave, and be prepared with appropriate gear like sturdy shoes and flashlights.
