Stop over between other parks
I've been using this as a night over stop before going on to the Black Hills or on my way back home. The first time I stayed the night over there it was a nightmare just because of this family or group of people showed up late and didn't comprehend quiet hours. So needless to say I had little to no sleep.
The other times I've stayed there it was quiet and not too many people around. Kind of buggy but that's expected with the water and all the shade.
