I had to go on the tour, especially because I also coordinated the route. The weather reported wasn't great either, but the hailstorm was still on the way there. I was lucky and was able to leave my rain gear in my backpack. It was a nice tour and my need to see rocks was satisfied. I love these rocky …

October 5, 2024,Grüne Hölle – Eulen-Horst Runde von Campingplatz Alteschmiede

Yesterday evening we arrived at the Alteschmiede campsite, which is outside the town. It would be very idyllic if there wasn't a main road on the other side of the "Sauer", as the river is called here. Before sunrise there was already noise from tractors driving corn.

June 27, 2025,Audiotour "Grüne Hölle" Bollendorf

The tour is challenging, so sturdy footwear is strongly recommended. The elevation profile is deceptive; it's constantly up and down, sometimes on difficult paths. All in all, it's a very nice hike with a great audio guide, but it shouldn't be underestimated. Four hours is a realistic (at a leisurely pace).
