Demanding and very beautiful ascent to the Teufelsloch! The views from the Waderweg and Teufelsloch into the Ahr Valley are beautiful! Sure-footedness and good footwear are required for the rather stony and rocky path.
There are two "main roads" leading to the Devil's Hole. Then a short, short climb (with a tether) leads up to the Devil's Hole. From the top you have a wonderful view of the "Black Cross" and the "Castle Are".
