Cottonwood Campground is a fantastic spot, with shaded sites beneath mature cottonwoods and sweeping views of the surrounding badlands near the South Unit entrance of Theodore Roosevelt National Park. It offers 76 sites—some reservable, others first-come, first-served—with flush toilets, potable water (seasonal), and a group site. During peak season (May 1–Sept 30), the nightly rate is $20; in the off-season (Oct 1–Apr 30), first-come, first-served sites are available for $10, making it a scenic and affordable overnight for Maah Daah Hey Trail hikers looking to regroup or explore nearby park highlights.
