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.

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/

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.
