A few years ago, I stayed overnight at Hackle Rd near Safford. It's BLM land. It's east of Safford along US-191. It was quiet there. Safford is not far from I-10 to the south.
To get to Hackle Rd. one makes a turn off of US-191 heading south onto Haekel Rd., then going straight where Haekel veers left.
Google Maps:
Turn right onto Haekel Rd
1.1 mi
Continue onto Hackle Rd
At the end of Hackle is an area which is a seasonal water reservoir, there is an interesting grouping of dragon's teeth to break up any overflow. That area near the end is used for shooting practice. There are sites along Hackle well before that area.
