Phoenix to Las Vegas by car
It's only 300 miles from Phoenix to Vegas, and the distance between the two along the shortest line could easily be covered in a day. However, the number of sights and the sheer variety of scenery along and around this route is simply staggering, and a leisurely drive gives an excellent introduction to America's Southwest.
Both Phoenix and Las Vegas are major transport hubs accessible by plane from all over the United States. Cars can easily be rented at either, and you can usually negotiate a free drop-off at the other end.
Day 1: Phoenix to Flagstaff

Day 3: Grand Canyon
