Olallie State Park, Natural state park in North Bend, Washington, US
Olallie State Park is a nature park in King County, Washington, running along the South Fork of the Snoqualmie River through old-growth forest and past several waterfalls. The park also includes six climbing zones at different difficulty levels, along with trails open to mountain bikers and spots used for fishing.
The land was acquired by Washington State Parks in 1950 and was first known as Twin Falls State Park, a name taken from one of its most visible natural features. The park later received its current name and grew as additional land was added over the years.
The name Olallie comes from the Chinook trade language and means berries, which points to the wild shrubs that line the trails here. In summer and early fall, these low bushes carry small, dark fruit that hikers pass close enough to touch.
The park is open throughout the year, but paths can become slippery in winter and sturdy footwear is a good idea at any time of year. Trails and climbing areas are most accessible from late spring through early fall, when conditions tend to be dry and manageable.
A hydroelectric facility sits roughly 330 feet (about 100 meters) underground beneath the park, generating power for the surrounding region without any surface signs. Visitors walking past the waterfalls are moving directly above an active power system that runs quietly out of sight.
