West of the state park, there are two federal camps with electricity and water. Wapiti campground and Rex Hale campground.
Or you can go through yellowstone to West Yellowstone and choose from several rv parks.
We stayed at Grizzly RV in West Yellowstone...very nice. Just a few miles to Yellowstone Park entrance. Just before the entrance is a great information center with lots of maps, etc. and Rangers to answer any questions.
The town of West Yellowstone has lots of neat little shops if you're into souvenirs...and the Grizzly and Wolf Discovery Center where you can see grizzlies and wolves up close.
