Hohler Fels (Happurg) is the name of a karst cave near Happurg on the Franconian Alb. In addition to the cave, the neighboring rock face also bears this name. The cave, which opens to the south, is 546 meters above sea level, below the former Celtic fortification called Houbirg (617 meters). The 16 meter long and six meter high cave on the southern slope of the summit was registered as a ground monument in the Bavarian list of monuments because of finds from the Stone Age and the Urnfield Age. There is a natural bridge with two openings in front of the cave.

The hollow rock is one of the "must-see" highlights in the Nuremberg region. In all seasons, the rock with its various caves, rock formations and viewpoints has its charm, even in the evening. However, this highlight is placed a bit too far north and not directly on the hollow rock.
