It begins in the Kolyma Highlands, Magadan Oblast, less than 100 kilometres (62 mi) from the Sea of Okhotsk, flows north, forms part of the border of Magdan and Chukotka, crosses Chukota, briefly enters the Sakha Republic and joins the Kolyma 282 kilometres (175 mi) upstream from the Arctic. Its basin is surrounded by: (west) branches of the Kolyma, (south) Penzhina and others that flow south, (east) Anadyr and (northeast) Bolshoy Anyuy. The upper Omolon is subalpine in the highlands, the middle is boreal forest and the lower part tundra. There is a Zakaznik in Chukotka to protect the forests.
Its main tributaries are the Molongda, the west-flowing Oloy (at 471 kilometres (293 mi), the largest tributary), Oloychan, Kedon and Ango.[2]
