The cave is hidden in a sheltered spot near the water, where you can easily imagine why the "cavemen" chose it as their place of residence. Today bats live there, so it is closed. But you can look inside and there is a bench and an information board about bats and the Neolithic finds.

Simply fascinating and definitely worth a visit to the eternal ice. Pleasant cooling off on hot days and you can also linger here very well. A sign explains the phenomenon of "Eternal Ice" in a way that everyone can understand. We will definitely come back here.

Shortly before the puppies are born, the pregnant she-wolf looks for a cave in which she gives birth to her offspring and houses them for protection. A wide variety of loopholes are useful for this, such as deep riverbank hollows, cavities under fallen trees or rock overhangs, hollow tree trunks, a gap between rocks and so on. Sometimes wolves also use abandoned burrows of other animals such as bear caves or beaver dams. Often caves have been used by wolves for generations. A cave in Jasper National Park was used eight times in 15 years. Another on Ellesmere Island may be even older. Bones up to 783 years old have been found in it. In an ordinary wolf cave, the birth chamber is at the end of a tunnel that can be up to 5 meters long in soft earth. The cave itself is often slightly elevated from the rest of the tunnel. The birth chamber has a diameter of about 90cm and is about 60cm high. The cave entrance has a width of about 50cm to 70cm and a height of about 38cm to 50cm. Often the cave is located near a water source and at an elevated place so that the wolf can spot approaching enemies early. The alpha male stays outside the cave for protection and often plays the decoy to lure approaching predators such as bears and eagles away from the cave, whose prey can be a very young puppy. Although wolves often defend their den against wild predators, they will usually run away when humans approach them. Over the years, wolves change their burrows and relocate with their offspring, covering a distance of more than 1.6km. This happens either due to a parasitic infection of the cave or disturbance from humans or other animals.

If the temperatures rise above 30 degrees and make us sweat a lot, then a visit to the Eternal Ice in Dornburg is recommended, where the outside temperatures are a pleasant 20 degrees and very close to the mountain even drop to 3 degrees. Everyone has probably heard of the eternal ice in Dornburg. I was also familiar with it, but unfortunately I had never been there myself in all those years. Due to a professional appointment, I was lucky enough to get to know this place for the first time. Coming from Frickhofen in the direction of Wilsenroth, there is a small car park on the right after the building yard, from which it is 300 meters to the Eternal Ice. The closer I get to the spot, the noticeably cooler it gets. Cool air from the mountain The place itself seems quite inconspicuous at first. Two large, barred openings allow a view of the mountain. You are at the end of a slope covered with basalt boulders. A clear draft can be felt in front of the openings. There is still snow in one of the openings. It was shoveled in in winter so that visitors to this place can get an idea of how cold it is in the mountain, Joachim Habel from the Frickhofen Culture and History Association explained to me. The thermometer goes down in no time and stays at 3 degrees Celsius. It was a funny coincidence, because only one day later the Hessenschau was there and reported on the coolest place in Hessen. Since the eternal ice is a unique natural phenomenon in the Westerwald, it is part of the Geopark Westerwald-Lahn-Taunus. In 1839, while demolishing basalt rock, workers discovered icing beneath the mass of rubble. Deep in the mountain, the rocks are frozen to a depth of eight meters. Now with the hot temperatures, this ice is not visible. It would also make no sense to remove stones, because then the ice would melt very quickly because of the lack of insulation. The mountain made of basalt rock has numerous cracks and crevasses that promote ice formation. Furthermore, this is favored by the large difference in height between the inlet and outlet openings for the air. These are all prerequisites for a chimney effect to occur. The rubble on the slope has a heat-insulating effect. The incoming warm air from outside penetrates the mountain and cools down. Cold air is heavier and sinks downwards - thereby drawing new air into this "chimney" from above. The cold air flows back out at the two ends of the tunnel. This cool draft can be felt very well when you stand in front of it. From there it is worth a slight climb to the Hildegardisfelsen, from which there is a wonderful view. The Hildegardis chapel and the fountain as well as the Celtic wall at the former Dornburg can also be discovered there. They are all part of the Blasiussteig. An interesting area on the doorstep and a recommended visit given the current temperatures.

The cave is a cultural monument and is among other things inhabited by bats. It is closed with a grille and is therefore not open to the public.

These sites showcase diverse geological formations, historical uses, and unique natural phenomena.
The region offers a variety of fascinating subterranean sites. You can explore the unique Eternal Ice at Dornburg, known for its perpetually cool temperatures. Other notable locations include the historical Laubach Valley Slate Mines, which serve as bat winter quarters, and the Buchenloch Cave, significant for its archaeological finds and natural protection status.
Yes, the Eternal Ice at Dornburg is considered family-friendly. It features explanatory signs that help visitors understand the geological phenomenon, making it an educational experience for all ages. The Dragon Cave & Reptile Zoo, while not a natural cave, offers both natural history and zoological exhibits that can be engaging for families.
The caves in the region offer diverse natural features. The Eternal Ice at Dornburg is famous for its unique ice formations, even in summer. The Large and Small Stone Chambers are fossilized parts of an ancient cave system, showcasing geological erosion. The Trass Caves Brohltal feature impressive rock faces formed from ancient basalt and lava flows.
Many caves in the Westerwald region have rich historical significance. The Langenaubach Basalt Quarry Tunnel is a man-made tunnel reflecting industrial history. The Laubach Valley Slate Mines were once active slate mines. The Buchenloch Cave has revealed Ice Age tools and animal bones, indicating early human habitation. The Trass Caves Brohltal were historically used for cold storage.
The difficulty varies. Some caves like the Buchenloch Cave are freely accessible. Others, such as the Bärenloch Prehistoric Karst Cave and the Bear cave, may have restricted access or require careful navigation due to their natural state. The Millstone Cave at Nerother Kopf is 18 meters deep and requires a flashlight for exploration.
Yes, several caves play a crucial role in nature conservation. The Laubach Valley Slate Mines are significant as winter quarters for various endangered bat species. The Bear cave is also home to bats and is closed to protect them, though you can look inside.
The region around Girkenroth offers numerous outdoor activities. You can find many hiking routes, such as those detailed in the Hiking around Girkenroth guide. There are also options for traffic-free bike rides and gravel biking, allowing you to combine cave visits with other adventures.
Many caves, especially those with perpetually cool temperatures like the Eternal Ice at Dornburg, offer a refreshing escape during warmer months. However, some caves, particularly those serving as bat habitats, might have restricted access during winter to protect the animals. It's always advisable to check specific opening times and access rules before your visit.
For most publicly accessible caves, standard hiking gear is sufficient. However, for deeper or less developed caves like the Millstone Cave at Nerother Kopf, a flashlight is essential.
