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
Sully Creek State Park Campground takes rigs up to 40 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.
