Hoover Dam Tours & TicketsStand in awe of one of mankind’s greatest accomplishments in engineering during a Hoover Dam tour! Within the arid desertscape of Black Canyon, Arizona, there stands an absolute goliath!

It became a symbol of hope for a nation gripped by the worst economic downtown ever seen: The Great Depression. And you can easily make a daytrip out of this man-made world wonder as part of a Hoover Dam tour from Las Vegas. It’s just a couple hours away from Sin City, making it one of the most popular things to do from Las Vegas. And, if you really want to go all-in, you can tack on a Colorado River rafting excursion, as well!
