Visiting the Little Bighorn Battlefield puts Hardin KOA in a useful geographic position: the site sits roughly 15 minutes from the monument, making it a functional base for travelers working through southeastern Montana's history corridor. The campground runs from April through mid-October, with nightly rates ranging from $30 to $75 depending on site type. Full hookups are available, including 50-amp electric, water, and sewer connections, and reservations can be made in advance.
Sites run close together. Several reviewers note that neighboring rigs can be as little as five feet away, so campers who prioritize separation may want to request a spot on the outer edge or ask about tree-shaded positions when booking. On the upside, some sites border a grassy area with a picnic table, and the grounds sit adjacent to alfalfa fields, so mosquito repellent is worth packing. The campground is also exposed enough to catch wind regularly.
Cleanliness comes up consistently across reviews spanning multiple years. Cannon W. describes "very clean facilities and pool area," and more recent visitors under new ownership report the same standard holding. The laundry room is large, includes vending machines, and connects to a dedicated dog wash station. Two dog parks are on site. A small pool provides afternoon relief in summer, and a pizza and wings counter operates out of the office building.
The sewer hookup setup has drawn a few practical complaints: at least two reviewers mention the connection sits elevated or lacks a standard screw-in fitting, which can complicate dumping with certain hose configurations. Staff reception has been mixed in older reviews, though more recent visitors report friendly and helpful camp hosts, suggesting a shift in management tone since new owners took over.
Travelers wanting a different setup can look at Hardin KOA Journey or check camping near Hardin for additional options in the area, including Loves Travel Stop roughly a mile south along the interstate corridor.
