He entfließt located on the 1952 m height Iltschirsee, fed, among others, by the mountain Iltschir ( 2352 m) coming and about 10 km long Iltschir.

In Sayan Irkut a bit to the west and a little to the south and southeast flows only. He passed through the massif of Munku Sardyk immediately southwest of the river location ( 3492 m ), after which he turns to the east and flows into the Tunkinskaya National Park.
