Secluded, ominously so
This camp ground had about three established campsites I believe, and they were all pretty private from one another. A creek runs through camp and it's heavily forested. Even during the busiest seasons this free campground is vacant but there is good reason for this.
The drive up was rough, take your vehicle at your own risk. If it's not AWD or 4WD you likely will not make it and trust me, you don't want to get stuck on the narrow road on the edge of a cliff. There's also a couple grave yards about a mile from the camp site which is pretty ominous.
There was a grouse preforming it's drumbing mating performance in the camp at all hours of the day and off and on through the night that got pretty annoying, but I doubt you'll have the same experience.
It is about 7 miles from Gardiner and there was some distressed screaming coming from the woods that cause me to decide to pack up camp and leave, so be weary. I'm certain it wasn't an animal (I'm a wildlife ecology student and am very familiar with animal calls in the area) but I have no idea what had went on.
Other than that, this camp site was pretty and probably the only quiet option near Yellowstone.
