Campgrounds and RV parks near Mandan, ND

History drives most itineraries here. Ft Abraham Lincoln State Park anchors the historic sites with the Custer House, reconstructed infantry post, blockhouses on the ridge above the river, and the earthlodges at On-A-Slant Village. Living history tours of the Custer House run every half-hour and last about thirty minutes, taking visitors back to 1875 when Custer and his wife lived at the fort. Tour passes can be purchased at the Visitor Center or Commissary. Outdoor activity centers on the Missouri and Heart Rivers. Trails inside Ft Abraham Lincoln State Park serve hikers, bikers, and horseback riders through the surrounding hills. Kimball Bottoms Recreational Area ORV adds off-road vehicle trails across a 400-acre area, a boat ramp, shoreline fishing, a sandbar, and beach access along the river.

The main camping season runs late April through mid-October. North Dakota state park campgrounds are open year-round, however comfort stations and water may not be available prior to May 16 when facilities are fully open. Reservations tighten quickly between Memorial Day and Labor Day, and summer weekends fill first, with sites often clearing out on Sunday afternoons. June has the highest number of rainy days in the Bismarck area, and thunderstorm activity peaks along with the mosquito load in the river bottoms. July and August deliver the warmest, driest camping conditions and the busiest bookings. September is a strong shoulder month with cooler nights, lower humidity, and easier reservations, though interpretive tours at the Custer House and On-A-Slant Village wind down after the summer season. Winter camping is possible but harsh. The coldest month is January, with an average high near 21 degrees Fahrenheit and average lows around minus 1 degree Fahrenheit. Snow accumulates across the plains, and most private RV parks reduce services or close. Travelers visiting October through March should confirm hookup availability directly with the campground.

Access is straightforward. Interstate 94 crosses the Missouri between Bismarck and Mandan, and Highway 1806 runs south along the river to the state park and county sites. Fort Abraham Lincoln offers a mix of mostly pull-through RV sites with hookups, modern sites, primitive sites, group sites, and cabins, including an accessible cabin. The state park campground provides water and electric hookups, picnic tables, fire rings, restrooms, showers, and a dump station, with a maximum RV length around 39 feet. Private parks in the Bismarck-Mandan area add full sewer hookups and laundry. Kimball Bottoms is primitive, with vault toilets and no hookups, and daytime OHV traffic near the boat ramp. Bring layers regardless of month, insect repellent for summer visits, and a plan for shade. Prairie wind is a constant factor, and severe thunderstorms can move through quickly between May and August.
