Omg! Save your money and do this tour! We were promptly picked up at our hotel by a super nice driver. Ryan was our guide to a group of six people. The weather was perfect, they provided snacks, lunch (Ryan even gave me his lunch because I was so hungry) and as much water as we wanted. We went into caves and hot springs, and saw numerous sheep in the mountains. We learned the history of the dam from our guide and enjoyed pleasant conversation along the way. Get off the strip and kayak the hoover dam with evolution expositions
