One of the most beautiful passages in the "Green Hell." You have the choice of continuing on the left or going right. We went back again to do both routes.

The region around Mettendorf, within the Southern Eifel Nature Park, is renowned for its unique geological formations. Key sites include the Teufelsschlucht (Devil's Gorge), characterized by narrow gorges, impressive rock towers, and massive stone blocks formed by Ice Age rockfalls. The area was once an ancient seabed 190 million years ago. Another significant feature is the Irreler Wasserfälle (Irrel Waterfalls), which are actually powerful rapids of the Prüm River, also shaped by large boulders from Ice Age events.
You can explore several natural monuments known for their dramatic rock formations and gorges. The Grüne Hölle Gorge (Bollendorfer Schweiz) features narrow rock passages with 15-meter high vertical and mossy rock walls, offering bizarre formations and views of the Sauer Valley. The Eulenhorst Rock Labyrinth is another remarkable site with steep walls and narrow, moss-covered crevices up to 15 meters high.
Yes, the Predigtstuhl Rock Formation is a particularly towering rock structure that offers panoramic views of the Sauer Valley from its elevated position. Additionally, the new 110-meter long suspension bridge at the Irreler Wasserfälle provides spectacular views of the Prüm Valley and the rapids below.
The natural monuments around Mettendorf are well-integrated into a network of hiking trails. For instance, the Teufelsschlucht area offers various marked trails, including the 'Little' and 'Great Rundweg Teufelsschlucht' (circular trails), and the 'Teuflische Acht' (Devil's Eight) which connects the gorge with the Irreler Wasserfälle. You can find more hiking routes in the region by exploring the Mettendorf hiking guide.
The Teufelsschlucht area is family-friendly, especially with the nearby Dinosaurierpark Teufelsschlucht, which offers an additional attraction for learning about Earth's history in an engaging way. The geological formations themselves, like the narrow passages and rock labyrinths, can be exciting for children to explore. The suspension bridge at Irreler Wasserfälle is also a fun and accessible experience for families.
The natural monuments around Mettendorf are beautiful year-round. Spring and autumn offer pleasant temperatures for hiking and vibrant foliage. Summer is ideal for longer days of exploration, while winter can transform the landscape into a serene, frosty wonderland, though some paths might be slippery.

Many hiking trails in the Southern Eifel Nature Park, including those around the natural monuments, are generally dog-friendly. However, it's always recommended to keep dogs on a leash, especially in ecologically sensitive areas like the Irreler Wasserfälle, and to respect local regulations regarding pets in nature reserves. Always carry water for your dog and clean up after them.
Given the varied terrain, including gorges and rock formations, sturdy hiking shoes with good grip are essential. Layered clothing is advisable to adapt to changing weather conditions. Depending on the season, rain gear, sun protection, and sufficient water are also recommended for a comfortable and safe visit.
