Skirting the boundary of the Olympic National Forest, the river turns northwest, passing through its namesake Bogachiel State Park.

[7] Below the Calawah confluence the Bogachiel River widens considerably and takes a meandering course westward through a broad valley.

The Quillayute River, formed by their confluence, flows west for only about five miles more before reaching the Pacific Ocean at La Push.

The river also supports large runs of Chinook and coho salmon and holds resident populations of coastal cutthroat trout and Dolly Varden.

Although the annual snowpack in these headwaters is considerable, they do not experience the heavy summer-melt sediment loads of rivers to the south (Hoh, Queets, Quinault).
