Best way to see Lake Mead and Hoover Dam. Three decks. Two are air conditioned. Food available on the boat. Reasonable priced hamburgers. Not fine dining but good food. Book ahead as they do fill up. Lots of tour buses come from Las Vegas. Air conditioned place to wait for boarding. Recorded tour. The boat Captain turns boat around so both sides get a great view of the power plant area. Plenty of time for pictures. Boat does run on time.
