Payson Az- KPAN
I see the last review for Payson was over a decade ago, so update.
They have signs on taxi ways for each ramp including the camping parking. They offer a courtesy car that allows you to go local as well as Horton trail, a good 25 minute drive, or the national bridge, etc.. basically a car for the day. ( Be sure to call airport manager to reserve the car- basically they leave the keys in car for you.) The campground remains one of, if not the, best sites for camping with your plane near California area ( yes better than oceano, Columbia and kern valley) You park and walk to site 50 feet away, they offer free wood, chairs, short walk to restaurant ( be sure to leave room for their famous pies). Town is 5 minute drive for supermarkets, food, gas, etc. A flight to Sedona is about 20 minutes away.
We were there during Labor Day weekend, all camping and RV sites around area full, 3 planes had 9 people sharing the whole airport campsite. No loud music, just piece and the sounds of planes flying in and out in the morning.
