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.


Through early 2013 a major redevelopment project prevents us from offering public tours of our hydropower operations. During the construction, however, you may still view the beauty of the falls from the observation platforms at our newly enhanced Snoqualmie Falls Park. Watch the video below for a virtual tour of the historic Snoqualmie Falls Hydroelectric Project.


The two-acre upper area of Snoqualmie Falls Park is open during the redevelopment project; in 2013 the park's lower trails and Snoqualmie River access areas will reopen to the public.

A Virtual Tour of Snoqualmie Falls Hydroelectric Project

Take a virtual tour of the world's first hydropower plant built completely underground, the Snoqualmie Falls Hydroelectric Project. Constructed in 1898-99 in the Cascade Mountains east of Seattle, the project's original Plant 1 powerhouse -- still operational today -- lies inside a bedrock cavity 260 feet below ground along the edge of Snoqualmie Falls. The Puget Sound Energy project's public park and trails are one of the Northwest's most-visited tourist destinations.
