The Wenatchee River runs roughly 53 miles through the heart of Washington. It is one of the most popular rafting locations in the state. In addition to the rafting, the river has both a Chinook salmon and steelhead population. Both populations thrived before the series of dams were placed along the Columbia River but have since diminished such that you will need to check the regulations regarding the steelhead season for this river. The summer Chinook run can be good in the late summer and early fall.
