The Grand Coulee Dam Visitor Center was built in the late 1970s as part of the dam’s Third Power Plant expansion. It was designed by architect Marcel Breuer to resemble a generator rotor. An evening laser light show was added in 1989. The center was retrofitted in 2004 for seismic, life-safety, and accessibility standards. The original laser equipment was replaced in 2013 and a new laser light show, One River, Many Voices, premiered in 2014.

In 2006, new exhibits and displays were installed. The exhibits interpret Grand Coulee's role as one of the main irrigation, flood control, and hydroelectric dams on the Columbia River. They also address the effects the dam has had on various groups of people, including Native Americans and early settlers. The new exhibits were designed, manufactured, and installed by Formations, Inc., of Portland, Oregon.

The visitor center is fully accessible and features hands-on exhibits, an auditorium, and restrooms.
