Freezout Lake - Dispersed Camping
Beautiful. No other campers, pit toilet perfectly clean. Bird hunters come and go. Stunning sunset. Can be windy at times.
Several RV campgrounds serve the Ulm area with varying levels of amenities. Great Falls RV Park offers big-rig friendly electric, sewer, and water hookups on level sites, though fires are not permitted on the premises. Prewett Creek RV Park provides full hookup sites with 50-amp service, while Brady RV Park accommodates both 30 and 50-amp connections for smaller rigs. Great Falls KOA remains open year-round with pull-through sites featuring concrete pads bordered by railroad ties, offering separation between camping spots. "The camper pads are gravel, not paved, and there are quite a few trees that provide decent separation/privacy between the sites."
For travel planning, many RV parks in the region require reservations, particularly during summer months when baseball tournaments and other events can fill available spaces. Military Park Malmstrom AFB Gateway FamCamp restricts access to those with military connections, providing concrete pads that are "mostly level...nothing is absolutely level." Cell service varies significantly throughout the area—Prewett Creek reports limited connectivity with just 1-2 bars on major carriers, while campgrounds closer to Great Falls typically offer better coverage. Dump stations are available at several locations, including the entrance to White Sandy Recreation Site when not closed for winter. Most RV parks around Ulm welcome pets, though some enforce restrictions regarding where animals can be walked.
"The bath house has clean toilet areas and clean showers. It is a good place to stop when you need electricity for air conditioning."
"It was convenient. The campsites are plentiful and not as close to eachother as others. Bathrooms spotless. After hours check-in was a breeze! Will use again."
"Since our rig stands tall at 13’ 6”, we played it safe and took the Hardy exit instead. Smooth sailing right to the park!"
from $56 / night
"We were the only nomads all the other campers were local seasonal fishing guides so it was very quiet. The lodge and rooms are nice."
"We found this campsite on our way to Glacier National Park when we needed a tent site for the evening. The staff was extremely helpful and friendly."
"We didn't have reservations and fit onto a site (#22) with a nice view of the distant mountains. Restrooms were always clean, even very early in the morning. We stayed two times."

"This is a cute spot if your feeling like camping but want to stay in cell service and have electricity and water access. Down by the river. Bring bug spray."
"Set on the edge of Historic Fort Benton, this is a great place to land for a night or a week or more. Lots to see, explore and experience in the area."
from $15 - $45 / night
"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.""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"












Beautiful. No other campers, pit toilet perfectly clean. Bird hunters come and go. Stunning sunset. Can be windy at times.
For a KOA, this is a comfortable spot. There are trees and places to walk with our dog. Clean restrooms. We booked a patio spot to enjoy the fall evening with a little more room, so splurging a bit. Spent last night a Benewah Campground in Heyburn State Park, and that was amazing, but KOA is a good choice when traveling x-country. Walmart very close, so a good opportunity to restock.
Stopped in overnight. Nice quiet spot on the lake. Toilets were very clean. Enjoyed the hike to the overlook. Hard to find what the off season prices were.
This is a town park that has a few camping sites that you back into. They all say trailer sites so not sure if you can have tents. It’s a first-come basis, free camping but not a lot of info or details available. There’s a very basic flushing toilet with a sink and electric outlets but no lights. It’s also very near the highway, separated by some shrubbery which is nice, but expect road noise. Very quiet little town.
Pulled in for an overnight. Few picnic table and bathrooms. Places to park or set up tent. Bugs we to the point I had to sleep in my car instead of tent.
After 3 days crossing the high plains, this nice campground with clean bathrooms and hot showers was just the ticket. I didn’t hear any traffic, very peaceful. All kinds of services a short distance into town: food, fuel, auto repair, dinosaurs.
We’re in a 30 TT and the sites a very easy back in. We stayed in site 15 on the lake side. Would certainly recommend the area. They have water spigots but it’s turned off got the season. But there is dump and fresh water at the black water park for $5.00 a self serve kiosk.
We happened up this cozy city park while passing through from Glacier to Yellowstone NP and decided to take a chance for a night. We were glad that we did. $10/night (3 nights max) sites were level on hard pack gravel, no hook ups, but there is a common water spigot, bathroom (no showers) & a dump station ($5). Payment is on the honor system by either drop box or QR code. There are two loops (east/west) with ~6 sites on either side of the creek. We were the only ones on our side of the park and stayed in site 8 which is a pull through as we have a 27’ travel trailer; it could easily handle 40’. Great walking path, disc golf course, grassy picnic area w/ pavilion & a dog park down the street. Bathrooms were dated and well used but were stocked with soap & paper products. All basic services within walking distance including Rex’s grocery store across the street. 4 bars 5G on T-mobile.
Nice spot, clean bathrooms… $32 per night for the night…
