We selected this $49 tour because we didn't want to commit a full day to Hoover Dam. IMO, this is the way to go. I called the day before to book the tour - easily done with their staff. The next day Bill picked us up at our hotel at 7:40AM. Given this is off season in Vegas there was only one other couple to pick up. So the five of us had a little travel party in the executive (16 pax) bus. Bill was just the right amount of "tour guide" - and all of it was informative and humorously presented. We enjoyed him. He provided good advice at each of our four stops (Boulder City downtown, the HD overlook, the HD visitor center and Dam walk and again in Boulder City on the return ride to observe long horn sheep grazing. The HD is absolutely amazing! And the visitor center/reclamation center was first class. Museum quality presentations, dioramas, video clips and artifacts that told the HD story from idea to design to construction to operation highlighting the key aspects of how our nation achieved this "wonder of the modern world" creation. Don't miss this experience. If you can, visit in the off season and regardless of season, visit early in the day. The crowds build by lunchtime.
