Discover the Grand Coulee Dam Tour in Washington
Experience one of the most impressive engineering achievements in the United States at Grand Coulee Dam, a massive hydroelectric and irrigation powerhouse on the Columbia River. Guided tours introduce visitors to how the dam was built, how it generates electricity, and how it transformed agriculture and development across the Columbia Basin. The visit combines indoor exhibits with sweeping outdoor viewpoints for a memorable, educational experience.
Why it’s special:
Grand Coulee Dam is one of the largest dams in the world and the largest hydroelectric power producer in the U.S. Its sheer scale, historic significance, and ongoing role in renewable energy make it a must-see industrial landmark.
History / Story of Grand Coulee Dam
Construction of Grand Coulee Dam began during the Great Depression as part of a bold federal effort to bring irrigation and electricity to the Pacific Northwest. Built to harness the Columbia River, the dam enabled large-scale farming in arid regions while supplying power to cities, industries, and wartime manufacturing. Over time, it became both a symbol of American engineering ambition and a reminder of the complex environmental and cultural impacts of large dams.
