There are lots of different designated sites along the whole main road. The spur road to sites 20-35 and then the fork to 26-35 is what I took, I stayed at site 33. My Nissan Versa handled the roads fine, just took it slow. No amenities except the bathroom at the trailhead a mile away. A good spot overall, some traffic down this road as I think the Virgin Dam Trailhead is towards the end of this spur road.
