The Chiwawa River originates in the Glacier Peak Wilderness of the North Cascades, on the southern slopes of Chiwawa Mountain and Fortress Mountain. It flows south through the Wenatchee National Forest, between Chiwawa Ridge to the west and the Entiat Mountains to the east.
The Chiwawa River empties into the Wenatchee River several miles east of Lake Wenatchee.
