The tour was a great experience. Our driver/tour guide, John, made the trip special. He had plenty of water on board which was appreciated. John was very knowledgeable about everything Hoover Dam and Lake Mead. With all his facts and figures about construction, etc., he truly made this a learning experience as to understanding the impact the Hoover Dam has on so many. We especially enjoyed the walk on the bridge that gave us such great views of the Dam. This tour is definitely worth taking.
