Numerous tunnels in the Hahnenbachtal valley bear witness to the mining past of this region... these tunnels even have tracks that were previously used for lorries

The path leads through two consecutive rock breakthroughs. But be careful, the headroom is very limited.

Old mine tunnel that I don't want to enter because of the risk of collapse.

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.

The Historisches Kupferbergwerk Fischbach is one of western Germany's oldest copper mines, dating back over 600 years.

Yes, the Herrenberg Show Mine is noted as being suitable for people in wheelchairs, offering an inclusive experience for visitors.
The Herrenberg Show Mine is open seasonally from Easter to October. During school holidays in Rhineland-Palatinate, it's open daily. Mines and tunnels can offer a cool escape on hot days, but always check specific opening hours for each attraction before planning your visit.

However, many of the surrounding hiking trails in the Bollenbach region are dog-friendly, allowing you to enjoy the outdoors with your pet.
Historical mines like Bierfincksgraben Mine and Altlayenkaul Mine Tunnel Entrance often have restricted access due to safety concerns, such as the risk of collapse or to protect bat habitats.

Always respect safety barriers and signage.
