Your next step
Swallow Falls 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 Maryland.
Nothing in Maryland 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.
