Vorotan
As one of the longest rivers in Azerbaijan, the Vorotan (Armenian: Որոտան; Azerbaijani: Bərgüşad or "Bargushad"; or "Bazarchay") is the main right tributary of the Hakari river in Transcaucasia. The river begins in the northern section of the Republic of Armenia's province of Syunik. It then flows into Armenia for 119 kilometers (74 miles) in a mainly south-easterly direction. The river then enters Azerbaijan, running for 43 kilometers (27 miles) through the rayons (districts) of Qubadli and Zangilan. From its confluence with the Vorotan to its confluence with the Aras River, the lower segment of the Hakari is sometimes believed to be part of the Vorotan.
The river generally runs across steep terrain, forming deep gorges in various locations. Along its path are the cities of Sisian and Qubadli. Six kilometers from Sisian, the river generates an 18-meter-high waterfall known as the "Shaki Waterfall" (Armenian: Շաքիի ջրվեժ). Near Tatev Monastery, the river forms a natural landmark known as the "Devil's Bridge." Mineral ponds may be found at the base of the travertine arch.
