Camping inside National Parks is always a treat. Cottonwood Campground makes exploring Theodore Roosevelt NP very accessible. The site is close to the river and you can easily walk to it from the campground. Very peaceful and secluded, it makes you feel like you are really in the wild. We saw bison and wild horses across the river from the campground. Some sites don’t have a lot of shade so get there early if you want a site with trees.
