I was looking for a safe place to solo car camp on my way to Colorado. On a Tuesday night it was just myself, an RV and the host RV. LOTS of mosquitoes until the rain started. I had put up my Clam Popup using lag bolts and an impsct drill into the hard ground. I was surprised to see it gone when I got up at 430 am. Once it was light out, I went searching and found it crumpled, but undamaged, near the lake. The rain softened the ground and the winds must have come up.
Anyway, i didn't see trash that others mentioned. If I hadn't had mosquito repellant I would have been miserable, but otherwise it was a nice campground with a pretty view. Very faint train noise, nothing that woke me (than again, i guess i slept through some decent winds).
I didn't use their restrooms due to other reviews (I travel with a potty bucket), so unable to comment on them.
The coordinates take you exactly to the gate (I mention this because I found myself worried about locating the access gate). I took my Subaru Forester to the left, and agree that you don't want to try that direction with anything lowered. That being said, a regular sedan going VERY slow over the bumpy parts could navigate it in it's current condition. I would have been hesitant if I had been towing my tiny trailer just because it would have put a lot of sideways tweaking on the hitch.
Don't take the 1st few campsites. Keep going to the edge of the canyon! There were at least 3-4 good sites with campfire rings before the road dipped waaaay down (to where I turned arouns as I wasn't sure if my AWD would make it back up). A couple of them directly on the canyon side.
I arrived around 5pm, and the winds kicked up shortly thereafter. Even with the wind I felt comfortable building a campfire as there as the vegetation is sparse. It was quiet, with no highway noise, and although I could see a few others in the other camping areas, they were far enough away to enjoy the quiet and take pictures without other vehicles in the background. I did take a pic of my neighbor and his rig, and he seemed appreciative of my offer to email it to him.
