This is a good spot if you just need to stop for the night. It's a great alternative to a truck stop or a Walmart because a) apparently there's an ordinance and Vegas Walmarts don't allow overnight parking and b) it's so quiet here / no idling trucks all night.
This appears to be a popular spot for dirt bikers to come and play as well. There was a small group that parked here and went off to ride, then zoomed back and zipped around the hills and jumps in this spot before packing up and going home.
One other camper stayed the night here when we stayed here. Plenty of space for people to spread out and there's room for many campers and for large rigs.
This spot is ideal because it's easy access from the freeway and yet it's far away enough and blocked by a little hill, so you don't get the loud freeway noise (you do hear it, but it's not at all bothersome). Access from the freeway is doable for most rigs, just take it slow as there are some ruts and dips. It's .4 miles from the freeway to this spot.
Google maps doesn't seem to recognize the dirt road that will lead you straight from the freeway to this spot and will try and take you along a more roundabout path. Check satellite view and you will see where to get off the freeway.
Good cell service here as well.
