Sol Duc Valley region of Olympic National Park, Washington

The source of the Sol Duc River lies within Olympic National Park on the Olympic Peninsula of Washington State. Coursing down from the Olympic mountain range, it twists and turns through the old-growth forest of the park, creating tranquil scenes like this one, as the Sol Duc makes its way toward the Pacific Ocean. And as National Park Week comes to a close, we encourage you to get out and visit some of the amazing spaces our national parks have to offer. Maybe soon you’ll find yourself in the Sol Duc Valley, enjoying this moss-covered landscape and listening to the river’s song in person.

The Sol Duc River is a river in the U.S. state of Washington. About 78 miles long, it flows west through the northwest part of the Olympic Peninsula, from the Olympic Mountains of Olympic National Park and Olympic National Forest, then through the broad Sol Duc Valley. Near the Pacific Ocean the Sol Duc River joins the Bogachiel River, forming the Quillayute River, which flows about 4 miles to the Pacific Ocean at La Push. Although the Quillayute River is short, its large tributary rivers—the Sol Duc, Bogachiel, Calawah, and Dickey Rivers—drain the largest watershed of the northern Olympic Peninsula, 629 square miles. The Sol Duc’s watershed is the largest of the Quillayute’s tributaries, at 219 square miles.
