The source of the Cheryokha is Lake Chereshno, located in a swampy area southeast of the town of Ostrov. The river flows northwest, enters Porkhovsky District, and close to the border with Pskovsky District sharply turns west. On a short stretch it makes the border between Porkhovsky and Pskovsky Districts. In 8.7 kilometres (5.4 mi) upstream from the mouth the Cheryokha accepts the Keb, its biggest tributary, from the right. The last stretch of Cheryokha constitutes the border between the city of Pskov (north) and Pskovsky District (south). The Cheryokha joins the Velikaya in the southern end of the city of Pskov.
The drainage basin of the Cheryokha includes the eastern part of Ostrovsky District, the western part of Porkhovsky District, the southwestern part of Strugo-Krasnensky District, as well as the eastern part of Pskovsky District.
The last 2 kilometres (1.2 mi) of the course of the river are listed in the State Water Register of Russia as navigable.[2]
