You'll want to have clear directions on this network of trails as there are many different side roads and washes that branch off of it. Interesting mines and ruins make it a fun route, but make sure you come prepared with water and supplies, as it gets very little use.
From Phoenix, head northwest about 35 miles on Highway 60. Before Morristown, turn left on Gates Road at mile marker 121 and head west. Bear right at large fork at 1.4 miles. Start of trail is on left next to river at 2.3 miles.
