The ridge is extended from northwest to southeast. It is located on the Yugorsky Peninsula, in the eastern part of the Nenets Autonomous Okrug. The ridge continues to the Vaygach Island, thus separating the Barents Sea and the Kara Sea. The highest point of Pay-Khoy is the mountain of Moreiz (467 metres (1,532 ft)). The ridge separates the drainage basins of the Korotaikha River (west, Barents Sea) and the Kara River (east, Kara Sea).
The Pay-Khoy ridge forms a curved orogen together with the Ural Mountains, the Vaygach Island and the Novaya Zemlya archipelago. The Pay-Khoy and Novaya Zemlya are younger than the orogeny that formed the Ural mountains. They were formed during the Cimmerian Orogeny between the Late Triassic and Early Jurassic.
