From there, it flows north and east, taking in two small tributaries and continuing to a point 20 kilometres southwest of the Ishpatina Ridge, where it turns south.

After approximately 60 kilometres, the river flows into Lake Wanapitei in the northeastern portion of Greater Sudbury.

The river is approximately 120 kilometres (70 mi) in length and is a popular wilderness canoeing route.

On June 2, 2013, a rail bridge crossing the Wanapitei River at Wanup collapsed, causing a train derailment.
