The Iron King starts in Prescott Valley and follows an old railroad bed from Glassford Hill Road into Granite Dells. The trail is 4 miles (one way) which connects with the Peavine Trail of Prescott.
The Iron King trail is a wide smooth trail that makes a slow accent from Prescott Valley to Prescott. During the heavy monsoon season the lower elevation parts of the trail can be muddy or washed out as the water collects toward the river bead near Glassford Hill Road. As you start the run you will be greeted by grazing antelope and cows as the trail cuts though open grasslands.

Beautiful.
Yep, I am truly amazed at all the beautiful places to trail run up here. I still have about 200+ miles of trail left to explore :-)
