There are several books available at Jeep dealerships and on Amazon. The one I have is "Guide to Arizona Backwoods & 4-Wheel-Drive Trails" by Wells & Peterson. Great book covers the entire state.
In the two weeks I've had my Trailhawk I've done both Schnebly Hill (from I-17 to Sedona) and Smiley Rock (from SR-89A near Jerome through Martin Canyon to Perkinsville). Both trails had been severely impacted by the recent monsoons and were a lot more rugged than the book describes. Lots of rock damage to my TH's plastic trim, rocker panel and fascias.
For the writer who did the back way to Crown King, I ask which back way? There is a route south from Prescott on Senator Hwy (an old stagecoach route), a jeep trail up from Lake Pleasant, both rough routes, and the "front way" from I-17 that you could drive in a Porsche. I've done the Senator Hwy in a Grand Cherokee and the front entrance in a Subaru Forester.
So many trails and not enough time.
