Match the campground's size limit and hookup level to a vehicle category, then plan the rest of the trip.

Near Lovell
NPSInsider tip · Bighorn Lake — 71-mile reservoir. Wild horse range overlooks. Quieter than Yellowstone area; locals fish carp + walleye.
Near Cody
StateInsider tip · Closest state-park camp to Yellowstone east entrance (50 min). Buffalo Bill Center of the West museum 5 min. Sailing-windy reservoir.
Near Hoback
USFSInsider tip · Granite Hot Springs at the end of the road — pair the camp with a soak. Hoback River fly-fishing. Cooler-priced alternative to Tetons NP camps.
Near Alpine
BLMInsider tip · Free dispersed sites along Greys River south of Alpine. Pack out everything. Moose + elk common. Quieter than the Tetons area but only 45 min away.
Your next step
Belle Fourche River Campground (Devils Tower NM) 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 Wyoming.
Nothing in Wyoming is bookable today — PickRV opens for bookings on October 25. 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.
