All the campgrounds in the area are just plain campgrounds. Not destination places where there are tons of things to do. Just a place to sleep eat and enjoy the outside.
That being said Medora campground is the best bet. Easy in and out, decent size sites, trees and full hook ups. The other full hook up campground in town, Red Trail, is small and tight.
Be sure to take in the musical it is OUTSTANDING. If you are a veteran check the times for the vet discount. The Pitchfork Fondue is very good. Eat under the awnings with great views. If they have two shows a day again this year my recommendations would the early show. They run on mountain time an hour later then central. You can see the countryside much better. The show is outdoors in a natural Ampitheater, the scenery is unbelievable.
Before, or after, your trip to Medora a couple of nights in Fort Lincoln State Park is well worth the time. The campground is on the confluence of the Heart and Missouri rivers, very nice campgrounds with full hook-ups. They have rebuilt General Custers home and several of the fort's buildings, the Mandan Indian Village (On-A-SLANT village) has rebuilt earth dome homes really interesting. Up on the hill they have rebuilt the 3 corner block guard towers. Well worth the day. Next day go 50 miles north to Washburn to the Lewis and Clark Center and Fort Mandan. The Fort Lewis and Clark spent the winter in. It is an extremely well done restoration. It is well worth the trip.
On your way back to Fort Lincoln take in the Heritage Musuem on the State Capital grounds and go to the top of the Capital Building, tallest building in ND. Take an evening ride on the river boat in Bismarck.
Just a little of the history in North Dakota but well worth the time.
