Good spot, easy access to Tucson area. The pinpoint and some reviews have it off snyner hill road, I'm not sure that area is legal to camp but I would not recommend it at all, a lot of trash dumped there and clearly used for target practice. The actual blm camping area is marked on Google maps as blm camp and in the triangle of San juaquin, old ajo hwy and ajo hwy. You will see cars/campers and signs with the camping rules noted, its clearly marked. Many low shrubs and trees so while sites are close they can feel separated. There is a gun range nearby that you can hear and pretty sure we also heard gun fire in that area off snyder hill road that I mentioned above.
Would stay here again, you may hear other campers (we had people playing music loudly but they stopped at 10pm) traffic noice isn't bad over night but there is a traffic light so you might was ear plugs and a sleep mask
