After a bad experience of trying to get in at one of the more primitive sites in northeast Yellowstone, we were extremely lucky to find out that this campground opened early this year. They usually arent open until July. Our experience here was wonderful. Very quiet, peaceful, and the host is a great guy. This is definitely bear country here so hard sided units only. There was a brutal bear attack here around 10 years ago leaving one dead and two severely injured, so just a heads up! There is a day use only area that is for that reason. Mosquitoes are were pretty bad here when we stayed.
