A very unusual sight. I have no idea whether animals or badgers live there, but the caves are now fenced off. Apparently, too many people wanted to know for sure.

I've never seen anything like this before. A bit hidden, but worth the drive.

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

Very well-done tour, with friendly guides. The small adjacent museum is included in the entrance fee. Tour possible with children. Duration approx. 45 minutes.

The caves are fascinating to look at, as they are buried in a clayey earth wall. I was able to think up nice stories about it, especially since the old Solmsbachtal railway line runs nearby.

The "caves" in the Waldsolms area are primarily historical mining tunnels, such as the Tunnel entrance of the Florentine mine, which offer a glimpse into the region's rich mining history. While these are man-made structures, some have become important habitats for wildlife. There are also a few natural rock formations and caves, like Brummbär Cave and Woolly Rhinoceros Cave, and the unique Kubach Crystal Cave, which is a natural show cave.
While most "caves" directly within Waldsolms are historical mining tunnels, the nearby Kubach Crystal Cave is a notable exception. It is Germany's highest show cave and its only calcite crystal cave, featuring impressive formations within 350 million-year-old limestone cliffs. Other natural caves like Brummbär Cave and Woolly Rhinoceros Cave are natural rock shelters, but without extensive speleological formations.
Several former mining tunnels and natural caves in the region serve as crucial wildlife habitats. The Gute Hoffnung Bat Cave is a prime example, providing a home for bats, toads, fire salamanders, and newts. The Woolly Rhinoceros Cave is barred to protect its bat inhabitants, and Brummbär Cave is known to be inhabited by badgers.
Many of the historical mining tunnels, such as the Tunnel entrance of the Florentine mine, are closed off for safety or to protect wildlife habitats. While you can often view their entrances and learn about their history, direct exploration inside is generally not permitted. The Gute Hoffnung Bat Cave, for instance, is part of a nature discovery trail where you can observe the entrance and its surroundings.
Yes, Kubach Crystal Cave is a family-friendly show cave. It offers guided tours lasting approximately 45 minutes, making it an engaging and educational experience for visitors of all ages. There is also an information center on-site with interesting facts about the region.
Kubach Crystal Cave typically opens for the season from the first weekend in April. Guided tours usually take place during the week from 3 p.m. to 5 p.m. and on weekends and public holidays from 10 a.m. to 5 p.m. The entry fee is 6 euros. It's always a good idea to check their official website for the most current schedule and pricing before your visit.
The Woolly Rhinoceros Cave is historically significant for its paleontological finds. During excavation work, bones of the woolly rhinoceros were discovered in this approximately 25-meter-deep natural cave. These remains indicate that woolly rhinos populated the area during the last ice age, about 10,000 to 30,000 years ago.
The Waldsolms region is excellent for various outdoor activities. You can explore numerous hiking trails, such as those found in the Hiking around Waldsolms guide, or enjoy cycling routes from the Cycling around Waldsolms guide. Mountain biking is also popular, with trails detailed in the MTB Trails around Waldsolms guide. Many of these routes pass by or near the cave entrances and historical sites.
Yes, several hiking trails in the region offer opportunities to see the cave entrances. For example, the Gute Hoffnung Bat Cave is located on a nature discovery trail (Widschweinroute). The Brummbär Cave is a small detour from the Lahn hiking trail. You can find more hiking options in the Hiking around Waldsolms guide.
For visits to show caves like Kubach Crystal Cave, comfortable walking shoes and a light jacket are recommended, as temperatures underground are consistently cool. If you plan to explore the areas around the historical mining tunnels or natural rock shelters, sturdy hiking shoes are advisable, as the terrain can be uneven and muddy, especially after rain.
The best time to visit depends on the specific cave. Show caves like Kubach Crystal Cave are typically open from spring (around April) through autumn. For viewing the entrances of historical mining tunnels and natural rock shelters, spring and autumn offer pleasant weather for hiking. Winter visits might be possible for some outdoor sites, but access could be limited by snow or ice, and many bat habitats are protected during hibernation periods.
While Kubach Crystal Cave is a popular show cave, you might find a more secluded experience at natural rock shelters like Brummbär Cave or the Woolly Rhinoceros Cave. These are often visited as part of a hike and offer a quieter connection with nature and history.
