There are actually many viewpoints along the tour, including a skywalk balcony overlooking Dornheckensee lake, Bonn, and the Rhine. Today, everything was slightly misty. There was a surprisingly large amount of snow on the paths and trees. There were an astonishing number of people out and about. We were able to walk safely and easily.
