RV campgrounds near Lewis and Clark National Forest range from full-hookup parks with 50-amp service to year-round facilities suited for big rigs. Great Falls RV Park offers big-rig friendly sites with electric, sewer, and water hookups, though spaces tend to be tightly arranged with minimal separation between units. Prewett Creek RV Park provides full-hookup sites with 50-amp electrical service in a more spacious setting along the Missouri River. "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," noted one camper about Prewett Creek. Helena Campground & RV Park includes market access alongside full hookup capabilities, making it convenient for resupply while traveling, though the gravel pads can require leveling blocks during wet weather.
Seasonal considerations significantly impact RV camping in this region, with many facilities operating from May through October. Great Falls KOA remains open year-round, offering all-season access to full hookup sites with both 30 and 50-amp service — making it one of the more reliable RV campgrounds for shoulder-season travel in Montana. Cell reception varies dramatically throughout the area, with Prewett Creek reporting limited connectivity (1-2 bars) while parks closer to Great Falls maintain stronger signals. Dump stations are available at most established RV parks, including Conestoga Campground in White Sulphur Springs, though some like Fort Harrison RV Park lack this service. For RVs requiring propane, options are limited near the forest - a camper noted that 486 Market in Cascade "fills propane tanks" alongside offering diesel fuel. Navigation to some RV campgrounds requires attention to clearance limits, particularly when approaching from I-15 where bridge heights may restrict larger motorhomes.
"Since our rig stands tall at 13’ 6”, we played it safe and took the Hardy exit instead. Smooth sailing right to the park!"

"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."

"Good, level, graveled sites. Full hookup pull-thrus that have a decent amount of space between sites. Bathrooms and showers very clean. Friendly staff."
"Only spent one night, but level sites, full hook ups, showers and laundry clean. An area to play games and we didn’t have our dogs this time but the dog zone looked good and clean."
ScoutFor 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.
TravelerStopped 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.
ScoutCamping late September in a truck camper, found it quite comfortable and adequate. Post-logging, (reportedly due to tree disease) the new growth is up to around 12' tall. There a nice brook babbling and some of the sites are along it. Sites are well separated and clean, as is the toilet. Parking sites are mostly quite level. There is a $15 camping fee. Only one other site was occupied. Road noises are fairly distant and tolerable. No T-Mobile coverage.
GuideThis 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.
TravelerWe’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.
LegendThis clean and neat KOA is just outside of Helena. We were arriving late so I spoke with a super friendly man in the office about after hours check-in (which was very smooth). Super clean and modern bathrooms. Quiet campground. Would stay again if passing through
LegendNot a ton of privacy between campsites but very well maintained with clean toilets and showers and garbage facilities but no water
RangerThis is a nice park for an inner city park. It is set down off the main road. Surprisingly I didn’t hear much road noise and I am awake a lot at night. It does have trees but most won’t help against the sun but I think it does help against road noise. The bath house has clean toilet areas and clean showers. It is a good place to stop when you need electricity for air conditioning.
RangerSUMMARY
We booked Grey Sandy on Hauser Lake and pulled our fifth wheel into a site directly across from the office. Shared water, shared fire pit, and enough dust to season a steak. The site was nowhere near level and tight enough that backing in felt like a timed event. Bathrooms were average. The camp store was average. The park itself is run down. Older long-term rigs, no visible upkeep, and the clear impression that nobody has invested a dollar here in a long time. We don't lock camper doors at a campground. We locked them here. We left a night early and did not ask for a refund.
**WHAT I LIKED
**The hosts. Genuinely kind people who seemed to actually care about the guests, which is more than the property can say for itself. The male host walked over and fired up the fire pit for the kids and us, and that was hands down the best part of the stay. The fire pit itself, once it was lit. The only nice feature in the park. Bathrooms and the store were average. At this campground, average counts as a win.
**WHAT I DISLIKED:
**Extremely tight site. Not level. Dirt and dust everywhere. Shared water and a shared fire pit. Dirt road in with steady traffic, so the dust never had a chance to settle. The lake is a long way off. If you are booking this for Hauser Lake access, look elsewhere. Overall condition of the park. Rough-looking campers parked long-term and no sign of maintenance or pride of ownership. The photos on the website do not match what you pull into. Go in with your expectations adjusted. We canceled a reservation in June when our camper broke down and never received our refund.
**WILL I STAY HERE AGAIN?
**Not the way it sits today. We left a night early and walked away from the money, which tells you exactly where we landed. That said, the campground has changed hands, and I know the new owner. There is real potential here. Level the sites, control the dust, clean up the long-term rigs, and update the photos so they match the property. Do that, and this becomes a solid Hauser Lake stop. I will check back in a season. As of this trip, it is a hard pass.

Trail exploration: Logging Creek Campground has terrain suitable for both day hikers and ATV users. "Endless trail. If you do some research in that area there is a place where there are some caves to explore, and another with fossils," notes a reviewer about Logging Creek.
Wildlife viewing: White Sulphur Springs area combines mountain ranges and open vistas. "If what you are looking for is exploring history and wildlife then this is the place. Campground is located on the edge of a small town with all pull-thru sites and FHU's," according to a camper at Conestoga Campground.

Quiet surroundings: Several campgrounds offer peaceful settings away from highway noise. "The real magic here is the setting—nestled in a peaceful valley that muffles I-15, this place is a nature-lover's dream," reported a camper about Prewett Creek RV Park.
Seasonal operations: Most RV parks close during winter months. "We have stayed here many times and enjoyed the area very much. Tv reception is good with all the major channels, ABC, NBC, CBS, FOX and PBS. Verizon and AT&T are good. The park WiFi is very good," notes a visitor about seasonal amenities at Conestoga Campground.
Road conditions: Access to some campgrounds requires navigation of unpaved roads. "Not going to lie. I didn't know what to expect and white knuckled a but driving my little old motorhome down into this ground. This is a bit of a trek. TOTALLY worth it if you are up for the adventure though," shared a camper about Logging Creek.
Facility maintenance: Quality varies significantly between campgrounds. "The bathrooms could use some updating. They are nice single occupancy toilet/shower combos but some had damage on the tile, missing soap dispenser, non functional paper towel dispensers," mentioned a visitor about Great Falls KOA.
Kid-friendly water features: Several campgrounds offer dedicated play areas. "Great little pool on the far side of the campsite is great for kids," noted a visitor about Logging Creek.
Playground access: Some RV parks maintain dedicated recreation facilities. "This is a very kid friendly campground, almost too much. Twice within an hour a train full of kids rolled by my site shouting. There is a large playground, volleyball court, basketball, and pools," reports a camper about Great Falls KOA.
Animal encounters: Scheduled and unplanned wildlife viewing opportunities exist. "Deer wandered into the campground throughout the night and morning. You can hear logging creek moving from no matter where you are," shared a visitor about Logging Creek.
Bridge clearance awareness: Some routes have height restrictions that require alternate approaches. "Since our rig stands tall at 13' 6", we played it safe and took the Hardy exit instead," shared an RVer about navigating to Fort Harrison RV Park.
Site leveling requirements: Many RV pads throughout the region require adjustment. "This site's gravel pad was not level, so we had to use our leveler blocks. Water pressure was good at about 50 psi," noted a visitor about Fort Harrison RV Park.
Dump station locations: Not all parks offer onsite dumping facilities. "I had to drive a gas station in town to do this," reported a camper about Helena Campground & RV Park regarding the lack of an onsite dump station.
