Spur of the moment, my wife and I have decided to travel this coming weekend to Phoenix, Arizona for nature photography and hiking. We will have 3 full days and a car, and we can stay in any motel or hotel, but we must fly into and out of Phoenix. I think anything within a 5 hour driving radius of Phoenix is fair game. The question is, with 3 precious days, what national parks, state parks or other areas should we see? There are so many great places nearby and it is hard to know which ones to choose. I have been previously to Organ Pipe NM and Saguaro NP so was thinking of heading east and/or north from Phoenix. Any input is much appreciated. Thank you!
