While the area in total only has about 6 miles of trail, if you do them all it will be a workout.
Park at Phippen Museum just of off Hwy 89 north of Prescott. The trail heads under the highway and you come out in an area where a Lockheed C-121G Super Constellation crashed on February 28, 1959.
Once past the memorial which has actual debris from the crash, you can take the trail in any direction. Be ready for flowy singletrack with plenty of rocks thrown in to play on. You'll encounter steep short climbs, drops and be on the look out for the "B Lines" that are more technically challenging.
