The river flows south for about west of the Yudoma Range and then flows southwest about (straight-line distance) to its mouth on the Maya. It starts about south of Mus-Khaya Mountain, the highest point in the Suntar-Khayata Range. It is formed from the junction of two rivers, one of which flows from a glacier. At the 'corner' began the long Okhotsk Portage which ran east-southeast to the Okhota River. About further was Yudoma Cross from which the Yudoma Portage led southeast to the Urak River and a longer horse track led to Urak Landing. North of Yudoma Cross a horse track led to Yakutsk. Near here the border between the Sakha Republic and Khabarovsk Krai joins the Yudoma and follows it to its mouth. About west of Yudoma Cross (straight-line distance) is the gold-extracting town of Yugorenok which is reached by a dirt road running south from Eldikan on the Aldan River.
