Hoover Dam, about 45 minutes from Las Vegas, remains one of the great engineering achievements of the 20th century, holding back the Colorado River to form Lake Mead.

Standard Tour

A standard visit includes the visitor center exhibits and views from the dam’s top, with the option to walk across to the Arizona side.

Powerplant Tour

A powerplant tour adds a guided descent into the dam’s interior, walking through the generator room and learning about the hydroelectric process firsthand.

Is the Powerplant Tour Worth It?

The interior tour offers a much more tangible sense of the dam’s scale and engineering than viewing from the top alone, worth it for most visitors genuinely interested in how it works.

Practical Tips

  • Combine with a stop at Lake Mead, the reservoir created by the dam, for additional scenery.
  • Security screening is required, similar to airport-style checks, given the site’s infrastructure significance.
  • Visit early to avoid both crowds and the intense desert heat, especially in summer.
