On our 4th day exploring Yellowstone, we made a little traveler error. We played and explored a little too long and when it was time to settle in for the night, even though it was a midweek day we found all of the park campgrounds full.  So we made our way out the West Yellowstone entrance to look for something and lucked out and found this campground!  27 sites that sit along​ Hebgen Lake.  Sites were clean and level, but not tons of privacy.   The lake was peaceful for a single night stay and because we did not get to explore very much it just made us want to come back again someday!
