If you head South out of Moab, there is a small town called Bluff. It has a nice little park with a great lady that runs it. We were only going to stay their over night and ended up staying several days. She can tell you many things to see in the area including Gooseneck State Park and also you are close to Monument Valley so we just took a day trip there. If you stay in Flagstaff the KOA is nice, but if you want a cheaper deal with no frills, Black Barts is fine and make sure you go have dinner and watch the melodrama that the college kids put on there in the summer....really fun! Flagstaff has a lot to see too. You can ride the ski lift up to snow bowl or just walk around downtown and visit the quaint shops. The weather in Flagstaff in the summer is amazing!
