The insider read
Bison herd grazes the campground regularly — wake to muzzles 10 ft from your tent. Loop B has the prairie-dog town next door. The 36-mile loop drive starts here.

Every fact above is sourced from the managing agency's canonical page. Cross-check fee, season, and size limit before you depend on them.
Match the campground's size limit and hookup level to a vehicle category, then plan the rest of the trip.

Near Watford City
NPSInsider tip · North Unit is the less-visited side. Bighorn sheep regularly on the Caprock Coulee Trail. 90% chance of solitude midweek even in summer.
Near Bottineau
StateInsider tip · Glacial lake in the Turtle Mountains. International Peace Garden 30 min for unique Canada-cross-over photo. Closest state-park camp to Canadian border.
Near Cavalier
StateInsider tip · Named for Icelandic settlers — Pioneer Heritage Center is the unique-fish ND immigrant history museum. Lake Renwick boat-friendly.
Near Medora
StateInsider tip · Closer to Medora than Cottonwood (TR NP). Maah Daah Hey Trail trailhead — 144-mile backcountry single-track. Medora Musical season (June-Sept) campers fill it.
Your next step
Cottonwood Campground (Theodore Roosevelt NP · South Unit) takes rigs up to 35 ft, so what you arrive in decides whether the loop works at all. If you don't own one, the same trip runs on a motorhome rented in North Dakota.
Nothing in North Dakota is bookable today. Dated requests are what we take to owners, so give us the window you actually want — you get one email the day a rig covers it, and nothing else.
