We go to Las Vegas many times but this is the first time we decided to set out on this 40 miles trip to see Hoover Dam. It about a 45 minutes drive. There are multiple parking in the area and we were lucky enough to score one that was nearby so we didn't have to walk too far. For such an attraction, I am surprise that they didn't make the sidewalk larger, we went during a low season so can you imagine what the busy season would be like?. We walked all the way to the end of the dam and walked back.
