Green River Gorge State Park offers a rugged canyon landscape with dramatic cliffs, a scenic river corridor, and opportunities for hiking, fishing, and wildlife observation just outside Seattle.
Green River Gorge State Park is located in King County, Washington, encompassing a deep volcanic basalt canyon carved by the Green River. The park stretches along the Green River valley and features steep cliffs, old-growth forest fragments, and unique geological formations created by past lava flows and river erosion. It provides a rich habitat for various wildlife species, including bald eagles, black bears, and salmon that spawn in the river. Historically, the gorge area was inhabited by the Duwamish people and later became a site of limited logging and mining activity. Today, the park is focused on preserving its natural environment while offering outdoor recreation to visitors. Activities such as hiking on rugged trails along the canyon rim, fishing for cutthroat trout and steelhead, and kayaking or paddleboarding on the calmer sections of the river are popular pursuits. Rock climbing opportunities are present on some of the basalt cliffs, but the area remains less developed than other nearby parks, appealing to visitors seeking a quieter natural experience. The park is accessible by road but maintains a relatively undeveloped character, balancing public use with ecological preservation. Its proximity to the Seattle metropolitan area makes it a valued green space for residents and visitors looking for outdoor adventure within a short drive.
