The Marvelous Bridges or Wonderful Bridges (Bulgarian: Chudnite mostove) are natural arches in the Rhodope Mountains of southern Bulgaria. The bridges were formed by the erosive activity of the once larger Erkyupryia River. It transformed the marble clefts into a deep-water cave, the ceiling of which eroded through time and collapsed. The Bridges are covered with vegetation like grass, bushes and pine trees.
