Old Tunnels as Homes for Bats

Underground cavities are of great importance to our native bats. Of the 20 bat species recorded in Rhineland-Palatinate, 14 regularly use old tunnels, caves, or cellars.

Hibernation - 5 Months on Low Energy

As pure insectivores, bats find little food in winter. To escape food shortages and the cold, they hibernate. All bodily functions are severely reduced, with their body temperature dropping from 37 to as low as 3°C. Their heart beats only about 10-20 times per minute, compared to the over 400 beats per minute when awake. The fat stores they accumulate in the fall must last until spring. If the animals are disturbed and awakened, they are often doomed to death. Therefore, the tunnels and holes are often barred to protect the animals sleeping there.

Late Summer Activity

But the old mining relics don't just serve as winter quarters: In late summer and autumn, many bats use old tunnels as courtship and rendezvous sites. Several hundred individuals can be observed swarming in front of the tunnels every evening. This swarming also serves to establish and maintain traditions. Therefore, old tunnels are particularly important for the conservation of endangered species.

The Hunsrück and its bats

The following species have been recorded in the old mines of the Hunsrück by the Rhineland-Palatinate Bat Conservation Working Group:

Greater Whiskered Bat
Lesser Whiskered Bat
Lace-Eared Bat
Natterjack Bat
Daubenton's Bat
Bechstein's Bat
Brown Long-eared Bat
Gray Long-eared Bat
Northern Bat
Barbastelle Bat
Pygmy Bat
Greater Hoofed Bat
Pontivated Pond Bat


The large number of abandoned slate mines, in particular, makes the Hunsrück an important habitat for bats in Germany.

Just a short detour from the Traumschleife, is the Bärenloch. There is also a bench to rest on.

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

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.

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.
