Green River Gorge is a stunning, rugged canyon in Washington State known for its dramatic cliffs, diverse ecosystems, and outstanding opportunities for hiking, fishing, and rock climbing.
Green River Gorge is a notable natural area located within the Green River watershed in King County, Washington. Carved by the Green River through volcanic basalt formations, the gorge stretches approximately 3 miles and features towering cliffs, unique geological formations, and a rich variety of plant and animal life. The gorge lies within the boundaries of several protected lands including state parks and natural areas, and is part of the larger Cedar River Watershed. The area is highly valued for its pristine water quality, contributing to the drinking water supply of Seattle, which prompts careful conservation efforts. Ecologically, the Gorge hosts mixed conifer forests and riparian habitats that support species such as black bears, cougars, bald eagles, and salmon in the Green River. Recreational activities focus heavily on hiking scenic trails that traverse cliff tops and riverbanks, rock climbing on basalt walls, fishing for steelhead and trout, and birdwatching. Popular landmarks within the area include the scenic overlooks at Flaming Geyser State Park and dramatic river views at the gorge rim. The gorge’s access points provide a wild outdoor experience close to the Seattle metropolitan area, offering visitors a relatively remote wilderness feel amid a highly urban region. Preservation efforts balance recreation with protection to maintain the gorge’s ecological health and landscape integrity. Overall, Green River Gorge attracts outdoor enthusiasts looking for adventure, solitude, and natural beauty in the rugged terrain of western Washington.
