I visited this campground for 1 night while driving across North Dakota. It's super easy to access from I-94, but you feel like you're a million miles away from the interstate. Arriving at the Teddy Roosevelt NP main entrance late in the day, the booth was closed and the "Campground Full" sign was up. I decided to check for myself and I'm glad I did. They sometimes put the campground full site up when the ranger leaves for the night- always check for yourself.

The campsites were basic- picnic table, fire ring, and close proximity to some basic bathrooms. My site was grassy and easy for a tent. The campground didn't allow hammocks or anything attached to trees. The rangers were very friendly and actively patroling the campground. There were NP events at the campground each night.

The cost for a site was $16 (and 20$ to enter the park if you don't have a pass). You cannot get change from the ranger and you cannot use a credit card to register. The closest place to get change, firewood, gas, etc. is Medora which is about 7 miles away. The convenience store there has anything you might want.

There are lots of great hikes accessible in the park, but the park is not crowded like other National Parks, so be sure to get a trail map and directions for hiking as all trails are not well marked.
