One of the three stalactite caves in the Bitburg-Prüm district is located on the Holsthum/Peffingen border. It is a high calcareous sinter cliff through which a small stream flows. A staircase leads up the Huwelslay stream. At the bottom of the path, a little to the side, you can climb up the rock to a bench in the rock. Access: - Over the hiking bridge from the L4, Schankweiler junction (signposted Holsthumer Rundweg HR) - From Holsthum, take the Oberdorf road - From Pfeffingen, take the Huwelslay road https://kulturdb.de/einobjekt.php?id=3603 https://www.naturpark-suedeifel.de/a-huwelslay-bei-holsthum https://kulturdb.de/einobjekt.php?id=8368

Hello @TS, your puzzle inspired us. Good thing we always have a headlamp with us! So we went through the gap and around the corner. There is no cave opening up here, but with a bit of goodwill a few people can stand or crouch here. But that certainly wouldn't have been possible for several days or weeks. On the other hand, there are enough hiding places in the rocks...

Although there is so much to wonder about, this one is very cool!! The nice thing is that you have to get in between them to continue your path

Lime sinter rocks on the western slope of the heath ridge between Holsthum and Peffingen. The name stands for Eulenfelsen (huwel => owl, lay => rock).

Very refreshing in summer! The tear lay is a lime sinter grotto worth seeing, in which lime deposits have given rise to unusual rock shapes. The explanation for this phenomenon: When rainwater seeps through the thick layer of sandstone on the plateau, it dissolves the calcareous binder that holds the quartz grains of the rock together. Where spring water emerges on slopes and valleys, but also on the banks of streams or rivers, the carbonic acid escapes from the soluble lime compound, the water evaporates and what remains is almost pure limestone. It is called lime sinter or lime tuff. The lime sinter settles along the flow paths of the water and covers mosses and plant parts with a stone crust. This is how fascinating rock shapes are created. The process of tufa formation continues steadily, the rocks "grow" like stalactites. (Source: www.naturpark-suedeifel.de)

a stone overgrown with plants from which water continuously drips.

I have not yet found any useful "historical" information about the Celtic cave, but the following youtube video of two hikers shows how blatantly interesting this section of the trail is! Listen too! Depending on your own level of fitness, the route with stone up and stone down can also be quite challenging! The video is not mine and I don't know the gentlemen. But it fits right here. https://youtu.be/9CS-s1d8YFU

The Mettendorf area, situated in the Eifel region, is known for diverse geological formations. You'll find lime sinter grottos like the Tränenlay Tufa Cave and the Huwelslay Tufa Cave and Waterfall, where limestone deposits create unique rock shapes. There are also impressive sandstone erosion landscapes with cave-like features, such as the Celtic Cave and the challenging Derborg Escape Crevice. Additionally, the region features spectacular gorges like Teufelsschlucht and Grüne Hölle, which contain numerous narrow passages and rock tunnels.
Yes, several options are suitable for families. The Cave at Märchenpfad Station 2 is a small, accessible cave that leads a few meters into the rock, ideal for younger explorers. The Teufelsschlucht (Devil's Gorge) also offers an engaging experience for families, with its mystical atmosphere and the nearby Naturparkzentrum Teufelsschlucht providing educational information.
The caves and rock formations around Mettendorf hold interesting historical connections. The Derborg Escape Crevice is historically associated as a potential hiding place during the Thirty Years' War. The Celtic Cave is part of a landscape where Celts once lived. Further afield, the Huel Lee in nearby Luxembourg showcases centuries of millstone quarrying dating back to Roman times, with visible chisel marks and robust pillars.
Most caves and gorges are accessible year-round, but spring and autumn offer pleasant temperatures for hiking. Be aware that the Hohl-Ley Cave, known as a bat shelter, is prohibited for entry between October 1st and March 31st to protect hibernating bats. The gorges like Teufelsschlucht and Grüne Hölle are particularly beautiful when the foliage is lush or displaying autumn colors.
Absolutely. Many of the cave-like formations are integrated into scenic hiking routes. The Teufelsschlucht features several trails, including the 17-kilometer 'Felsenweg 6' and shorter circular routes. The Grüne Hölle is a highlight of the 'Grüne Hölle Tour Bollendorf' circular hiking trail. The Celtic Cave is located on Teufelspfad 8 and Felsenweg 6, while the Tränenlay Tufa Cave is passed by the Felsenweg 2.
Given the nature of the terrain, it's advisable to wear sturdy, comfortable hiking shoes with good grip. Layers of clothing are recommended, as temperatures inside rock formations and gorges can be cooler than outside, even in summer. A headlamp or flashlight can be useful for exploring darker passages, especially in places like the Derborg Escape Crevice.
Yes, the Huel Lee (Hohllay Cave) in Berdorf, Luxembourg, is very close to the German Eifel region and Mettendorf. It's a unique site blending natural sandstone formations with historical man-made features from centuries of millstone quarrying. It offers an impressive, almost architectural, underground space and is a prominent feature on the Mullerthal Trail (Route 2).
Generally, no special permits are required for public access to the gorges and most cave-like formations. However, as mentioned, entry to the Hohl-Ley Cave is prohibited between October 1st and March 31st for bat protection. Always respect local signage and conservation efforts.
The region around Mettendorf offers a wide range of outdoor activities. You can explore extensive MTB trails, enjoy gravel biking routes, or go cycling on various paths. The natural landscape is ideal for hiking, with many trails connecting different natural landmarks and viewpoints.
While some locations might be reachable by local buses, a car is generally recommended for exploring the caves and gorges around Mettendorf. This provides the most flexibility to visit multiple sites, many of which are located in more remote natural areas. Parking is usually available near popular trailheads and attractions.
The Teufelsschlucht, located between Irrel and Ernzen, is a spectacular gorge formed by massive rockfalls around 12,000 years ago. It's a geological wonder, offering dramatic insights into the region's history with formations carved from a 190-million-year-old seabed. Its narrow crevices, towering rock formations, and moss-covered sandstone walls create a mystical atmosphere, making it a popular hiking destination.
The Grüne Hölle near Bollendorf is known for its unique microclimate. The cool, damp conditions and minimal sunlight in its narrow rock passages create a distinct ecosystem with vibrant green mosses, algae, and lichens. It features impressive rock formations and is a highlight of the 'Grüne Hölle Tour Bollendorf' circular hiking trail, recognized as one of Germany's most beautiful.
