Cow Belles Corral Campground (Musselshell County Fairgrounds)
There is a donation post at the west entrance. Use it. That is the whole deal here: Musselshell County leaves the gate open at the county fairgrounds on the east edge of Roundup and asks travellers to chip in what the stop was worth, and the Roundup Chamber prints the posted rules plainly -- 'Donations for maintenance are accepted in the donation post on the west entrance. Donations are greatly appreciated.' No fee is charged, but this is a donation site, not a freebie, and a county that trusts you with fourteen days deserves the cash. What you get is a big, flat, unfussy piece of ground: open grass between mature cottonwoods with no marked or numbered sites, so you pick your spot and park -- travellers report room there for the largest rigs, which is rarer than it sounds on this route. The Musselshell River runs alongside and Roundup itself is a couple of minutes west for fuel, groceries and a meal. It is a genuinely good overnight on US-12 between Billings and Lewistown, and one of very few free municipal or county stops left in a state where most towns now price their camping. The rules, straight from the posted list: camping longer than 14 days is prohibited unless you arrange it with Musselshell County; trailers, tents and vehicles cannot be left unattended over 48 hours; quiet hours 10 p.m. to 7 a.m.; and hold it to 15 mph through the grounds. Restrooms are SEASONAL -- roughly mid-to-late May through early-to-mid September, weather depending -- so outside that window assume there is nothing open and be self-contained. We are NOT claiming drinking water: several listings say water is available, but no official source confirms it, so haul your own. One reviewer flags a posted warning about falling branches -- look up before you park under a big cottonwood, especially in wind. TWO THINGS TO KNOW BEFORE YOU TRUST THIS ENTRY. First, this is NOT Roundup City Park -- they are two different places, and the chamber lists them separately, so do not follow a map pin that says 'city park'. Ours points at the 4-H Road access to the county fairgrounds, about three quarters of a mile from the city park. Second, the sources disagree on price: the chamber, The Dyrt and Campendium all describe it as free with a donation post, and one traveller wrote 'the campsite is free, but there is a sign asking for donations, which we did' -- but Good Sam lists it 'From $11 / night' with no detail. We have graded this MED and are telling you about the disagreement rather than hiding it. Arrive with cash either way. The fairgrounds also hosts fairs and rodeos, so expect the place to be busy or closed to campers around events. Call Musselshell County at 406-323-2804 to confirm current rules and whether anything is on before you count on a bed here. Buy your dinner and your fuel in Roundup, pack out everything you brought, and leave it better than you found it. We have not visited this site.
