This place is everything we look for when boondocking. It's quiet, open, easy to get to with our class c, flat(ish), cell service, and places to hike/walk around. There was nobody else around when we stayed here for 2 nights in May.
The road is nearby but barely visible and you can hardly hear the cars. The rocks (tufas) are really neat and fun to climb.
There's absolutely no shade so the sun makes it feel hotter than it is. And the wind comes through somewhat unpredictably so we couldn't keep our awning out.
It's surprisingly clean, I mean there's some trash which is to be expected, but not huge amounts of it.
There are a couple of little narrow roads you can take to find a more secluded spot, but I wouldn't attempt it unless your vehicle can handle it. There are a couple of random big dips to get past, and really there aren't very many camping opportunities past the big giant open area by the rocks. The big main area is huge and would easily fit several campers.
Great place to boondock!
