The primary metropolitan area to visit in Arizona is also one of the more fun road trip destinations you can find in the state. Phoenix is not only the capital, but it's where to take your Arizona rental car to discover more urban attractions. Many travelers visit in the winter months when the temperatures are perfect because the summer temperatures can be consistently over 100 degrees. While Phoenix has plenty to occupy your time with during a vacation, it is also centrally located to many other cities in Arizona. Phoenix includes neighboring cities such as Scottsdale, Tempe, Glendale, Peoria, Mesa, and Chandler. If you're visiting one of the neighboring cities, you'll need a rental car to get around quickly.
