This recreation area is part of Lake Oahe
Sprawling, well-appointed campground on the outskirts of Bismarck, run by the park and rec district. Lightly forested with large campsites for tents and RVs. The park has showers, bathrooms, an amphitheater, disc golf, a playground, and a group area. It is very popular with locals. It is also incredibly cheap and was an easy stop-over campground.
We visited the Natural History Museum at the capitol which was free and nearby, and had lots of fun dinosaur bones and displays.
Nice tent area and plenty of camper pads. Day use areas available with shelters and playgrounds. Disc golf course. Vault toilets. Close to Bismarck and all it has to offer.
We were passing through on our way between Minnesota and Glacier and needed a place to stay. Pulled in at 8pm in the summer and there were lots of places open. The tent side ($12/night) is one large green grassy area with tables here and there with nice tall trees. There's a gross pit toilet on the tent side, or if you walk on a pathway just a little bit you'll make it to the nicer bathroom on the RV side that has showers and flush toilets. Nice playground. Lots of bees.
