The Rissloch waterfall and gorge are definitely worth a visit. You can reach it from the (busy) Wanderparkplatz-Risslochfalle via a steep path through the gorge or you can go to the waterfall via the walk below. The climb will be much quieter, less steep and you will encounter a small waterfall along the way.
This hike in the Bavarian Forest National Park goes from the spa town of Bischofsmais to the Teufelstisch, a special rock formation at 901 meters high, to which a beautiful legend has been attributed. On the ridge you have a nice view of the castle ruins of Weißenstein and the provincial town of Regen.
