We made reservations for a trailer 6 months in advance since we read campgrounds full early and we brought our dogs so needed hookups in case of hot weather. This campground is PERFECT if you want to see both the Grand Tetons AND Yellowstone. It’s literally 3 minutes from the south entrance to Yellowstone. Very large pull through spaces. Firepits, picnic tables, and bear lockers at every spot. Laundry available. Clean bathrooms and free showers. Store, gas station, and restaurant/bar. Super quiet and empty during the day cause everyone is out exploring. Fills up at 6pm but never loud.
