If you only have a few hours and can only take one tour you have to take Gray Line's Original Mini Hoover Dam Tour.

As you stand on top of this great structure that spans Black Canyon, you will understand why Hoover Dam is rated one of America's Seven Modern Civil Engineering Wonders.

Completed in 1935, it remains the number one sightseeing attraction in Nevada.

With two hours at Hoover Dam, you will have the opportunity to take the optional Bureau of Reclamation Discovery Tour for only $11.00, which includes: Entrance to the multi-million dollar Tour Center and a movie of the Dam's construction. Informative talks by Bureau of Reclamation guide staff are presented at a number of separate strategic locations. Be sure to also visit the museum and exhibit areas.
