Upon arrival at the Hoover Dam, head to the Theater Level, where there are murals, maps, photos and other displays that provide an introduction to the Hoover Dam. Watch a short presentation, "How the West was Won," that showcases the part that the Bureau of Reclamation played in taming the rivers, settling the West and growing the country’s food.
Next, you’ll visit the power plant generators on the guided Discovery Tour. To get there, you'll take the large elevators 500 feet down into the walls of the Black Canyon to walk through a 250-foot-long tunnel and view the 650-foot-long Nevada wing of the power plant and its eight huge generators. Stand on top of it at the Penstock Viewing Platform, where you can view one of the four 30-foot-diameter pipes that transport nearly 90,000 gallons of water each second from Lake Mead to the hydroelectric generators in the powerhouse.
After the Discovery Tour, visit the Exhibit Gallery, which highlights some of the natural history of the region and presents a picture of how the Hoover Dam was constructed and how it presently operates. From the Dam Overlook, you can soak in the beautiful panoramic view of the Dam, Lake Mead and the Colorado River.
