Secluded spot if you can make it here
I did not stay here, but I wanted to check out the area.
First off, I wouldn't recommend any kind of camper come to this area. The road is narrow, and there are trees and scrubs that will scratch your vehicle (my vehicle already has a bunch of scratches). You definitely need a high clearance and maybe 4X4 as the road crosses washes and sand. There are 2 or 3 sites at the beginning of the dispersed area that a small camper could get to, but after .3 miles, the road gets rough and narrow.
Overall, it's a pretty great spot for some tent camping, and I imagine not many people make it out here. I only saw 2 vehicles at the very entrance of the area. So you could get a great secluded spot in the middle of a ton of Saguros if you make the trek out here.
No services. Pack in, pack out. 1 pr 2 bars of Verizon service.
