Built during the depression-era between 1933 and 1942, Grand Coulee Dam is the largest concrete structure ever built and remains one of the engineering marvels of the modern world. A 50-minute guided tour is free of charge to the public and available only on a first-come, first-served basis.

The visitor center is open daily and Grand Coulee's laser light show "One River, Many Voices" is held nightly at Grand Coulee Dam starting the Saturday of Memorial Day Weekend through September 30.
