Come to AZ and ride some sweet desert single track. Fly into PHX and get yourself to Picket Post Trail Head the end of the AZT 300. Do a loopish ride that JoeyDurango and I came up with for his fall trip

After completing the AZT Old Pueblo Loop get yourself back to PHX for a motel refresh and then head north on the Flagstone course to the Black Canyon Trail. Ride the BCT as an out and back also a stunning newish trail. The farther north the newer, mostly a BLM project some of the Gila is similar in terms of BLM trail standards. These two rides will give you a great sampling of AZ bikepacking and depending on how you route yourself you can make things harder or easier in a few key places.
