The Siyoma River runs through the upper reaches of the Varzob Gorge in the Tajikistan mountains

The Siyoma River Gorge is situated 54 kilometers along the Varzob highway, almost directly opposite the Varzob Climbing Camp. It is a popular destination for mountain hikers and on weekends, both local residents of Dushanbe and visitors from other cities and countries can often be found here. The Siyoma River starts at an elevation of 1782 meters above sea level, at its confluence with the Varzob River near the road, and rises to 3000-3200 meters in its upper reaches.
