Not sure how the roads are during or after rain, as it didn't rain significantly while we were there. But the roads are dirt and seemed fairly substantial. Our biggest concern was clearance because of some ruts, etc., but we navigated it ok. There is also Old Ajo Highway BLM Dispersed right next to Snyder Hill, which looked to have very easy in and out and big open flat space. Lots of big Class As were parked there.
