The Green River cuts through sandstone and shale to form a deep, rugged canyon with numerous “kettles” and other grotesque formations carved by the water. Small falls gush down the rocky walls. A bridge from which there is an excellent view of the Gorge spans the river, but vehicles are not permitted to stop on it. Catwalks are provided at lower levels. Heavy forest growths creep to the brink of the five-mile canyon. Tourist resorts have commercialized the gorge to some extent, and motorists are usually charged a parking fee of 25 cents, which permits the inspection of the canyon at close range. Cabins, provisions, and meals are also available. Confusingly, this is also called Hanging Gardens State Park.
Green River Gorge
Points of Interest 
Green River Gorge Historic District
This scenic gorge was the center of much of the early coal mining in western Washington. Three towns, Black Diamond, Kummel, and Franklin, sprung up in the 1880s to support the mines and miners. Kummel, the smallest mine, closed in 1916. Franklin, whose mine all but closed in 1953, has disappeared. It is notable for bringing in African-Americans to break a strike in 1891. Only Black Diamond survives.
