Campgrounds and RV parks near Roundup, MT

Roundup sits in central Montana along the Musselshell River, about 50 miles north of Billings on U.S. Highway 87. The town is small and services are limited, so most RV travelers use it as a base for hunting, fishing, and prairie touring, or as a quiet stop between Billings and central Montana destinations. In-town RV options are modest: Ideal Motel and RV Park offers a compact, year-round lot on Main Street suited to shorter rigs, and a free donation-based city campground on the east edge of town provides additional overnight parking with water but no hookups. Most travelers who want full amenities drive south to the Billings area, where Billings Village RV Park, Yellowstone River Campgrounds, and Billings KOA Holiday cluster near the Interstate 90 corridor with full hookups and pull-through sites. Mountain Range RV Park extends the options west of the city. The surrounding landscape is high plains and Bull Mountain foothills, with the Musselshell River cutting through Roundup itself. Expect ranchland, sandstone rims, and long sightlines rather than forested mountain scenery.

Private RV parks in and around Roundup and Billings, including Ideal Motel and RV Park, Billings Village RV Park, Yellowstone River Campgrounds, Billings KOA Holiday, and Mountain Range RV Park, are booked directly through the campground by phone or their own websites. Call ahead for larger rigs, since some in-town lots cap RV length around 36 feet. Montana state parks and Fish, Wildlife and Parks fishing access sites are reserved through the state's system at recreation.mt.gov, and federal campgrounds on Custer Gallatin National Forest or BLM lands use Recreation.gov, typically opening a rolling six-month reservation window. For summer weekends and hunting season, book as early as the window opens.
