It is a natural bridge, formed from travertine, located on Vorotan River in Syunik region. The length is ~30 m, the width is 50-60 m. There are number of mountain springs around the bridge, the waters of which have colored the walls of the canyon in pink, yellow and green. The Goris-Tatev highway crosses the Devil's Bridge. There are various hypotheses concerning the name "Devil's Bridge". For instance, there is a theory, that less water flows in under the bridge, than it flows out. This is due to the fact that mineral waters are dripping from above.
