There are just moments in life where something is just so awe inspiring that you really are looking for words! Hoover Dam is one of those things that leaves you in silence as you marvel at the sight and inspired by the hard work! I've been to Hoover Dam probably 6-8 times as when visitors come to Vegas with us that have never been need to see it! I've never left uninspired! The massiveness of the structure, the time in which it was built, the circumstances for which it was built, the people who built it, and the archaic tools for which they used is simply amazing! It is absolutely worth your time and money to do the tour down inside the dam. The tour is so informative, and informs you of myths and truths of the construction of the dam. Once the only way to Arizona was to cross the dam, but now the equally impressive Pat Tillman bridge is that avenue which offers a walk out to see a aerial view of the dam. You owe it to yourself to take a tour bus from the strip, or rent a car for the short 45 minute ride out to Hoover Dam!
