The tour of Europe's only gemstone mine was very interesting. Even the dogs were allowed along.

Before and after relatively wet trails, narrow and overgrown.

The old tunnels in the Hunsrück make the region an important habitat for various species of bats. Here you'll find one of these tunnels, which can be lit outside of hibernation times so you can take a look inside.

As of April 2023: Great and interesting tour. Prior registration is currently mandatory, so don't just drive there and hope that you can go into the tunnels. Toilets, a small kiosk and a sale of gemstone products are available at the entrance. It is also great for hiking around the tunnel.

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 Steinkaulenberg Gemstone Mine is the only mineral mine in Europe that is open to visitors. I was surprised at the amount of gemstones to be seen in the mine's galleries, so I highly recommend a visit; However, you have to register online or by phone in advance. The path through the mine takes about 1 hour and is barrier-free and therefore easy to walk on. It takes about 15 minutes to walk from the parking lot to the mine.

The Gemstone Mine is the only open-to-visit visitor mine in Europe. Expert guides explain how the gemstones are formed. Opening times are from March to November daily from 10:00 a.m. to 5:00 p.m. You should register beforehand. We found it very interesting. The temperature is 9 to 10 degrees.
