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.


Watch the videos below for a virtual tour of the historic Snoqualmie Falls Hydroelectric Project.


Above the falls is the two acre Snoqualmie Falls Park with observation areas and signboards about the history and operations of the facility. A new boardwalk connects the upper area to a lower level observation platforms allowing visitors to view the falls from the bottom. Parking is available at both levels of the park.


Through early 2013 a major redevelopment project overhauled the hyrdrofacility and surrounding parklands. More
