Hoover Dam

About Hoover Dam

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between Nevada and Arizona. Constructed between 1931 and 1936 during the Great Depression, it was dedicated by President Franklin D. Roosevelt in 1935. The dam impounds Lake Mead, the largest reservoir in the United States by volume when full. Named after President Herbert Hoover, it remains a National Historic Landmark and a major engineering achievement of the twentieth century, drawing millions of visitors annually.

What's inside

Visitors to Hoover Dam can explore the power plant, where generators produce hydroelectric power. The dam features observation areas on both the Nevada and Arizona sides, offering views of the structure, Lake Mead, and the Colorado River below. The Visitor Center contains exhibits about the dam's construction, history, and operational functions. Interior tours may include access to tunnels, the generator room, and other operational spaces. The Mike O'Callaghan–Pat Tillman Memorial Bridge, opened in 2010, provides an additional vantage point from above the dam.

How long to spend

A typical visit to Hoover Dam lasts between one and three hours, depending on the depth of exploration. Self-guided tours of the exterior observation areas and Visitor Center require less time. Guided tours that include interior access to the power plant and additional operational areas extend the visit. Travel time from Las Vegas adds approximately forty-five minutes each way. Visitors should account for potential delays at security screening points. Combined visits with Lake Mead or the memorial bridge may require a half-day or longer excursion from the city.

Summer months bring extreme heat in the desert environment, with temperatures frequently exceeding one hundred degrees Fahrenheit. Spring and fall offer milder conditions. Winter visits may encounter cooler temperatures and occasional precipitation.

What to watch out for

Security screening is mandatory for all visitors entering interior facilities; prohibited items include weapons and certain electronic devices. The desert environment presents risks including extreme heat, limited shade, and dehydration; adequate water and sun protection are essential. Elevated surfaces and steep drops near exterior observation points require caution, particularly for children. The memorial bridge walkway exposes visitors to traffic noise and wind conditions. Altitude at the dam site exceeds one thousand feet above Las Vegas, which may affect sensitive individuals. Cell phone service is unreliable in portions of the approach corridor.
