Great BLM dispersed
KOFA WILDLIFE REFUGE AND ADJACENT BLM.
Good free Dispersed camping on roads (gravel dusty and washboard also) heading into the KOFA mtns. BLM lands first couple miles off hwy 95. 14d camping limit, no water, no toilets, no dumpsters, no designated sites, just pure boondocking. On hwy 95 south of Q. Cell signal good on TMobile for me.
The Palm cny road is most popular due to the Palm cyn hike to see rare native palms, but day use is busy (7+ mi of gravel road access to TH).
Lots of campers spread out with lots of room mostly on BLM lands the first 3.0 miles from hwy 95. A refuge host is present at refuge boundary but not sure of their role. The Refuge rules notes 14d camping limit in a calendar year (but BLM rules note 14d in one area then have to move 25mi to another..). Note the dispersed campsites in the refuge are restricted to 100ft from the road, a restriction the BLM does not have.
