Vishera (Perm Krai)

The Vishera (Вишера) is a river in Perm Krai, Russia, a left bank tributary of the Kama. It is 415 km long, and its drainage basin covers 31200 km2. The Vishera freezes in late October or early November and stays under the ice until the end of April. There are diamond deposits in the basin of the Vishera.

The Vishera used to be part of the Cherdyn Route and is still considered one of the most picturesque rivers of the Urals. It starts on the extreme northeast of Perm Krai, near the border with the Komi Republic and Sverdlovsk Oblast. It flows on the west foothills of Ural Mountains and is a mountain river for most of its length. There are many rapids and shoals in the channel and many rocks along its banks.

The Vishera Nature Reserve is along the upper reaches of the river.
