Snoqualmie Falls is 1.5 mi. n.w. on SR 202. Plunging 268 feet over a basalt cliff, this is one of Washington's most popular natural attractions. Volume varies depending on the flow of the same-named river, and is at its most impressive after heavy rains that occur periodically from November through March. When the river is at flood stage it flows across the entire precipice and is an awesome sight.
Much of the river's flow is diverted into two power plants. A 1,215-foot tunnel channels water into a power plant located 270 feet beneath the surface; built in 1898, it was the world's first completely underground facility of its kind. A second plant a quarter of a mile downstream was built in 1910 and enlarged in 1957.
There's a landscaped park on the north side of the falls, and a covered gazebo—perched at the edge of the cliff 300 feet above the river—overlooks the plunge. The half-mile River Trail follows a steep descending course down to the river and the base of the falls.
