Best map resource for Prescott area. Between that and Google earth your covered.
Lots of trail options that are bike pack friendly ie. ride-able with a load.
For roads use Wolf Creek to Senator Hwy (FR52), then choose either Walker Rd/Black Canyon Hwy ( some pavement miles ), or the Goodwin/Mayer Rd depending on how you want to exit. There are so many variations on those themes you could go crazy.
Have fun with the research. Let us know what you pick.
