The Hoover Dam Classic Tour offers ample time for exploring this National Historic Landmark and engineering wonder of the world. See live presentations, a fascinating film on the dam’s construction and history, an exhibit gallery and observation deck. Venture down to the observation room in the power plant to view the massive generators. You’ll also encounter dramatic views of both the Colorado River and Lake Mead, the largest man-made body of water in the Western Hemisphere. This tour uses a 10-passenger Tour Trekker, a vehicle specifically designed for sightseeing and off-road adventures.
