RV travel guide
Yellowstone County
County seat Billings, 2,632 sq mi across Montana. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on Yellowstone County
Billings is Montana's largest city (population 117,116) and the only metro east of Bozeman where any RV rental, propane refill, or full-service grocery routes within a single 4-block grid — the practical reentry point for any rig coming off the Beartooth Highway from Yellowstone's Northeast Entrance. Yellowstone County wraps the Yellowstone River's eastern descent from Park County to the North Dakota border, with the Rims Sandstone bluffs at Pictograph Cave State Park holding 2,000-year-old hunter-gatherer rock art that anchors the county's archaeological tourism.
Pompeys Pillar National Monument 28 miles east of Billings preserves Captain William Clark's 1806 carved signature — the only physical surface evidence of the Lewis & Clark expedition's outbound journey, and a BLM-managed unit with no RV-friendly campground onsite (nearest at Tongue River Reservoir SP).
