Best RV Parks & Resorts near Belt, MT

KOA 8/24: The area we stayed in is for medium sized rigs or smaller. It was wooded and very nice for a KOA. The larger spaces are in a newer and less shady portion of the campground.
FUN POOL PARK, PLAYGROUND, PETTING ZOO, SHORT TRAIL. GREAT ICE CREAM

Overall Rating: 4 Security: No locked gate Usage during visit: pretty full on weekends Visual Privacy Between Adjacent Sites: no Site Spacing: close Pad surface: blacktop Reservations: yes Campground Noise: Fairly quiet Outside Road Noise: no Through Traffic in campground: no Electric Hookup: yes Sewer Hookup: yes Dump Station: yes Potable Water Available: At site Bathroom: very nice Showers: yes / nice Pull Throughs: most all Cell Service (AT&T): fine Recent Weather: very hot Insects: none Host: staff Rig Size: large

General: Just about every option you could ask for (except for tents): 50-amp FHU pull-thru, 30/20-amp with w/e(back-in and pull-thru), FHU with patio, glamping tent, one and two-room cabins and cottages. 

Site Quality: Different from many KOAs we have stayed in is that the camper pads are gravel, not paved, and there are quite a few trees that provide decent separation/privacy between the sites. The sites are bordered by railroad ties, and some are a tighter fit than others. A few of the sites at the end of the row before the glamping site appeared a little overgrown. As is usual for a KOA, our site was assigned upon check-in. The first site we were assigned didn’t work out for us since our electric cord could not reach the pedestal. Be aware that electric connections are shared between two sites so if you do not have an extension cord, you may have a problem (or need to be reassigned which was easily done for us). 

Bath/Shower House: Accessed by code. All-in-one units with soap and paper towels. They were clean. 

Activities/Amenities: Many and varied including a water playground (guests can join you here by paying a fee), petting zoo, train, dog park, yard games, bike rentals, propane fill, dump station, laundry, ice, ice cream, and free pancakes. There was even live entertainment! 

We don’t typically stay in KOAs or RV parks (mainly because of cost and lack of privacy between sites) but they are good for us when we need showers, laundry, and a dump station. Although still more than we like to spend for camping, this one was a pleasant surprise with the number of trees on the property. The staff was exceedingly friendly!

We booked online and got a super helpful email with everything we needed—directions, campground info, Wi-Fi password, rules, and even a bridge clearance warning at Exit 244(“Canyon Access”). Since our rig stands tall at 13’ 6”, we played it safe and took the Hardy exit instead. Smooth sailing right to the park! Camp hosts Jesse and Ronnie gave us a warm welcome and guided us into FHU Site 8. We did a bit of the ol’ RV shuffle to back in our 40’ 5th wheel(thanks to a small drop-off across the road), but with a few adjustments, we were in and leveled. The site was nice and long, with room to park across, and hookups were well placed—electric toward the back, water and sewer mid-site. Connectivity check: Verizon gave us 1 bar, T-Mobile 2 bars, and the campground Wi-Fi wasn’t too shabby(6.03 Mbps down/ 1.05 up). But for streaming, our T-Mobile home internet saved the day with blazing 59.4 down. The bath house and laundry area were clean and convenient, with 2 washers and 2 dryers($2 each). There’s a fenced dog area too, great for traveling pups. The real magic here is the setting—nestled in a peaceful valley that muffles I-15, this place is a nature-lover’s dream. We spotted deer casually strolling through the campground and bighorn sheep doing their thing up on the rocks. The park is spacious, beautifully laid out, and refreshingly quiet—most folks are out fishing during the day and resting easy at night. No playground means fewer kids, so if you’re looking for tranquility, this is your spot. The Missouri Inn Restaurant and Bar, right next to the campground, served one of the best cheeseburgers we've had on our travels. Just up the road in Cascade, the 486 Market was surprisingly well-stocked with reasonable prices. It also has a gas station with diesel, offers 20 lb propane cylinder exchanges, and fills propane tanks. After over 300 campgrounds in the past 7 years, Prewett Creek easily lands in our top 10. And Jesse and Ronnie? Top-tier hosts—friendly, helpful, and genuinely great people. We’ll definitely be back, and next time, we’re staying longer!

Dearborn Fishing access site has one campsite tucked away in the corner of the fishing access area next to the ADA Vault Toilet. Site has a picnic table and metal fire ring. The area has very little room to park so those camping their will likely have the site to them selves. The river access is a step set of stairs dropping down to the river so you not be having fishing boats or canoes using the site to access the river, but you can access the site from the river. A private residence is next to the fishing access site but the placement of the campsite does not make it feel like your in someones yard. The advantage of the one campsite is once you have your vehicle parked your site including the picnic table and fire ring can't be seen by others visiting the area. The site has no water or trash service.
