For anyone planning to visit Arizona, this is definitely the best guide you can bring with you. Although I wish it had more photos give a clue as to what you'll be seeing, the excellent maps, detailed descriptions, and sheer volume of information provided more than makes up for it. I had only a few days in Arizona and didn't have time to waste, so it was important that I find the best places to see while I was there. This book proved to be absolutely vital for my trip. Without it I would never have found many of the interesting sights that I visited. In short, don't go to Arizona without this book.
