The mouth of the Anna mine is not really accessible now in winter (as of February 2025). A small pond has formed in front of it. I don't know whether it will disappear in summer.

Very beautiful caves. Highly recommended. But you should really bear in mind that there are a lot of stairs that you have to climb back up. It is REALLY tiring for inexperienced stair climbers, so you should think carefully about it. Other than that, the entire area around it is very beautiful and informative. There is a good Italian restaurant nearby.

456 steps to reach a depth of 70m. An absolute highlight for young and old. I would pay the small fee for the photo permit again at any time. This is the only way to at least capture the experience for later 😊 The guide explained the history of the cave to us in a very exciting way. Even our little one was enthusiastic

In addition to the Unique Crystal Cave, there is also a rock garden with many geological descriptions. At the end you can enjoy the great view of the Weinbachtal and look at the castle ruins of Freienfels. Also a great destination for children

The Anna mine was an ironstone mine and was operated from 1836 to 1925 and from 1937 to 1945. In 1864 the mine went to the Friedrich Krupp company and in 1900 it was one of the most productive mines in the Lahn area.

For a unique natural phenomenon, visit the Eternal Ice at Dornburg. This natural monument is known for its consistent cool temperatures, often dropping to 3-10°C, even on hot days, due to a natural 'chimney effect' within its basalt rock formations. It's a fascinating example of the region's geology.
Yes, the Kubach Crystal Cave is a notable site. Located 50 to 70 meters below the surface, it is Germany's highest show cave and its only calcite crystal cave, featuring formations up to 350 million years old. Guided tours are available.
