[1] The Kuoyka flows north of the Arctic Circle across a lonely, desolate area of the Olenyoksky District devoid of settlements.

In its last stretch the Kuoika turns in a SSE direction entering the Central Siberian Plateau area.

It meanders strongly in its southernmost section within a wide gorge until it meets the left bank of the Olenyok 473 km (294 mi) from its mouth.

[1] The last, tortuous stretch of the river was described in such terms by Yuri Tsenin in Vokrug sveta: Its channel bends so whimsically in a wide canyon that sometimes one can't understand in which direction it flows.
