The tunnel is about 100 meters away from the vitality tour, but is signposted

The Schielenberg roof slate pit in the Breitenthal district near Herrstein is the site of several dozen different fossils. https://www.mineralienatlas.de/?l=57751 The slope is criss-crossed by several farm roads that lead to the tunnels above the huge slate rubble heaps. Most are fenced off as bat roosts, but some are also accessible. The rubble heap must not and should not be entered, as the loose layering tends to quickly fall off and everything ends up directly on the street! So stay on the economic routes.

But there is “No drinking water” coming from the source

The copper ore mine on Schloßberg dates back to the middle of the 16th century. It took 20 years to work on the search tunnel. After about 28 meters the copper core was exhausted. Behind the gated entrance stands a statue of St. Barbara, the patron saint of miners.

The Schloßberg spring rises approx. 12 m inside the Schloßberg. It was set in a stone basin and ensured the Naumburg's drinking water supply, including the stately wine house, until the 18th century. From then on, for unknown reasons, the yield of the spring decreased so much that the residents of Naumburg had to rely on the water from the Bärenbach flowing in the valley. The spring still runs as a constant trickle all year round. Source: http://www.baerenbach.de/Freizeit/Baerenroute/Schlossbergquelle/

It is actually surprising that the topic of "dry wall" is the subject of an information board, while a little off the hiking trail at the end of a path a tunnel opens up that leads to a widely branched mine. In addition to protecting the bats, this may also be the reason why a grid prevents further access after about 10 meters. From here, however, you can already see numerous tunnels leading downwards, upwards and to the side, which are only poorly secured or not secured at all, so that one can quickly sink into the bottomless holes filled with water. Exploration would be exciting but potentially very dangerous. The wood found in the Bierfinckgraben mine allows the mining activity to be dated to three periods around 1500, around 1700 and 1750.

In fact, you have to look for the mouth hole of the studs. The only clue is a gold mine symbol on a single tree. There you have to climb the slope on the right, come to a small level and stand in front of the tunnels that meet in the mouth hole. You can follow the one on the left for a good 30 meters into the mountain, the one on the right is wall-high with water, so that you need rubber boots. In a good 20 meters the water seems to end and the tunnel continues. Incidentally, the tunnel opens up the same copper ore layer "Yellow Gang" as the opposite copper mine "Hosenberg".

The region around Mittelreidenbach, particularly within the Saar-Hunsrück Nature Park and near Idar-Oberstein, offers a variety of subterranean experiences. You can find historical mining tunnels, natural rock formations, and even a unique gemstone mine. These sites provide insights into geology, local history, and serve as important habitats for wildlife.
Yes, the Bierfincksgraben Mine is a historical site with widely branched tunnels dating back to periods around 1500, 1700, and 1750. While access is restricted to protect bat habitats, you can still observe the entrance and learn about its past. Another significant historical site is the Schlossberg Spring, which includes a 16th-century copper ore mine.
The Steinkaulenberg Gemstone Mine in Idar-Oberstein, about 9.9 km from Mittelreidenbach, is Europe's only gemstone mine open to visitors. You can take an hour-long underground tour through 400 meters of tunnels, seeing crystals like agates and amethysts still embedded in the rock. The mine is well-lit, and guides explain gemstone formation and mining history. You can also participate in a 'gem camp' to search for your own gemstones. Reservations are strongly recommended or mandatory. More information can be found at museumsportal-rlp.de.
Yes, the Wildfrauenloch (Wild Women's Cave) is a rock cave steeped in local stories and legends. Tales speak of a wild woman who lived there, and it's also associated with ancient Celtic goddesses as a sacred site. Its appeal lies in its mythical and historical significance, offering a unique cultural experience for those interested in folklore. You can find more details at rlp-tourismus.com.
The Descent to Fischbach Cave is a popular cave and trail offering a flowing descent. It features small rocks, roots, and a stream crossing, providing a wonderful view of nature. It's appreciated by the komoot community for its enjoyable route.
Yes, the Slate Mine Tunnels within the Saar-Hunsrück Nature Park are crucial habitats for various bat species, serving as winter quarters and rendezvous sites. While usually barred to protect the bats, some tunnels can be lit for visitors outside of hibernation periods, offering a glimpse into this important ecological site. The Bierfincksgraben Mine also serves as a bat habitat.
The Altlayenkaul Mine Tunnel at Steinbach is an unslated tunnel a few meters from the Soonwaldsteig. It leads into the mountain for about 40 meters, opening into a mining dome. Another interesting site is the Yellow gallery, a copper ore mine where you need to look for the entrance, marked by a gold mine symbol on a tree. These offer a more adventurous exploration for those seeking less crowded spots.
The region around Mittelreidenbach offers various outdoor activities. You can find numerous MTB Trails, Gravel Biking routes, and Running Trails. Many of these routes pass by natural features and historical sites, allowing you to combine your cave exploration with hiking, cycling, or running through the scenic Saar-Hunsrück Nature Park.
The Steinkaulenberg Gemstone Mine is particularly family-friendly, offering guided tours and a 'gem camp' where children and adults can search for their own gemstones. The well-lit tunnels and educational aspect make it an engaging experience for all ages. While other sites might be more rugged, the gemstone mine provides a safe and interactive underground adventure.
The best time to visit depends on the specific cave. For mines that serve as bat habitats, like the Slate Mine Tunnels, visits are typically outside of bat hibernation periods (usually spring to early autumn). The Steinkaulenberg Gemstone Mine is generally open during warmer months, but it's always best to check their specific operating hours and make reservations. The consistent temperature inside mines (around 9-10 degrees Celsius) makes them a cool escape in summer and a sheltered option in cooler weather, though access might be limited in winter for some sites.
The Steinkaulenberg Gemstone Mine is noted for being barrier-free within its tunnels, making it accessible for many visitors. However, the walk from the parking lot to the entrance involves some inclines. For other historical mines and natural caves, access can be more challenging, often involving uneven terrain, narrow passages, or steps. It's advisable to check specific accessibility details for each site if you have mobility concerns.
