The Wonderful Bridges are rock phenomenon also known by the name of the Rock Bridges. It is located in karst Erkyupria River valley in the Western Rhodopes at 1,450 meters altitude, at the foot of Golyam Persenk peak. The bridges were formed by the erosive activity of the highest-water river of the past, which has formed the marble cracks and turned them into a deep cave river, over the years ceiling of the cave has grown thinner and even at places started to crash. Most probably the debris was eventually carried away by the river waters. There were left only two marble bridge-shaped boulders. The large one (situated upstream) is 15 metres at its widest and 100 metres long, and shaped by three vault arches, the largest of which is 45 metres high and 40 metres wide. The Erkyupriya River flows under the middle-sized arch. The smaller bridge is located 200 metres downstream. It is unpassable, 60 metres in length, with a total height of 50 metres, 30 metres at the highest place of the arch. A third, very little and hardly reachable bridge-like formation follows, constituting the entrance of a pothole cave where the river waters disappear underground, and show back up after 3 km.
