Snoqualmie Falls Hydroelectric Project 

Visit Snoqualmie Falls

Puget Sound Energy's Snoqualmie Falls Hydroelectric Project, built in the late 1890s about 30 miles east of Seattle, is one of the Pacific Northwest's oldest hydropower facilities and home to the world's first hydroelectric plant built completely underground.

The energy project's Snoqualmie Falls Park and its trails are open for day use year-round. The park is one of the region's most-visited tourist destinations. Map it.


The 12-acre Snoqualmie Falls park contains picnic areas, rest rooms, education kiosks and signs, and cliffside observation areas for viewing Snoqualmie Falls. The lower park area offers a trail through forested wildlife habitat, an education kiosk and restrooms, a kayak/canoe launching area, historic interpretive displays, and a riverside boardwalk and observation platform for viewing Snoqualmie Falls.

Parking in the main park area can accommodate tour buses and approximately 450 cars, and the parking lot in the lower park has 3 bus stalls and space for 41 cars.
