This is a nice park that is worth an overnight to learn about expedition history, native Mandan culture, and more. The park is a stop of. the Lewis and Clark Historic Trail , which was the draw for us. The park has a nice campground, with RV sites set back jn the trees and large tent sites right in the Missouri River! There are also camper cabins to rent. The park has a nice visitor center with terrific displays, moany aboutLewis and Clark, also a reconstructed Mandan encampment, plus the home and barracks of Custer and his cavalry. Running through the park is a cool trolley that takes you to historic points within the park, then on into the town of Mandan 6 miles away. The campgrounds have nice bath houses, plus a playground for kids and naturalist programs with an enthusiastic staff. Nice experience!
