Hoover Dam

If you're in to structures the Hoover Dam is really a must but even if you're not really into structures, it's a nice sight. When you drive from Las Vegas to The Grand Canyon you can choose to drive by the Hoover Dam. You can park your car very close to it and have a walk on the Dam. When you're standing on it, you'll have a better view than from the car. You can see better how deep is actually is and you have a great view from the building of the bridge next to it. If you like, there is an information point of the Hoover Dam. I don't think that's free (i didn't go here) but it suppost it won't be that expensive. So if you're in the neighbourhood, just take half an hour to stop here.
