"With high wind warnings forecasted we looked for somewhere to tuck in for the night out of the wind. This spot worked out perfect. It is a no frills city park that isn’t in the city."
"Close to town but also get the camping experience. Great fishing and plenty of room for everyone. Great hosts"
"The lake has lots of open shoreline. There is tons of local traffic. A lot of the same vehicles that just drive through 10-20 times a day. It's a bit annoying."
LegendWith high wind warnings forecasted we looked for somewhere to tuck in for the night out of the wind. This spot worked out perfect. It is a no frills city park that isn’t in the city. The restrooms were not open but we enjoyed a quiet evening to ourselves.
ScoutPretty nice spot quick off the highway. Not a lot of people while I was here. Mostly camper trailers. I do a hammock. My site had a pump with great flow and my electric socket worked. Bathrooms weren’t bad, showers were fine.
GuideAn hour and a half east of the St. Mary entrance to Glacier National Park--great when you are (like us) headed east after a long day in the park--this municipal campground exceeded expectations. A pleasant, well-maintained loop of sites, many with electricity and some with water (although the spigots, on some sites, were bizarrely distant from the normal location near the electrical box, requiring long hoses). Set in the area below the dam for Lake Shel-oole, with access to the lake from the campground loop. The lake was low during our stay, so not clear what activities might be available when the water is higher. Well patrolled, with a bathhouse in the center of the loop, old-school but serviceable, containing flush toilets and hot showers. Relatively far from any highways and train tracks, so (for this part of the world, and unlike many commercial campgrounds) was very quiet.
TravelerNice campground but not many amenities. You fill out a form and submit payment in a box at the entrance. Restrooms are rustic but have showers. Has Electric and Some sites have water and some have picnic tables. Saw the Sheriff making rounds.
LegendNo issues getting to this campground (CG)— it’s right off I-15, making access simple and straightforward. There’s plenty of RV parking at the office, and check-in was friendly, quick, and easy. We were escorted to pull-through site 31 with full hookups (FHUs). All sites in this CG are pull-throughs, arranged in a large outer and inner circle layout. Utilities are centrally located on the pad, making it easy to position them to suit your setup. Water pressure was strong— we used a pressure reducer. The picnic table and yard are on the driver’s side, but it works well in this setup. We had solid connectivity: 4 bars on both T-Mobile and Verizon. The CG’s 5G Guest Wi-Fi was surprisingly good, delivering 124 Mbps download and 10.2 Mbps upload. Our T-Mobile home internet hit 28 Mbps download. The CG also sells propane and has a clean, well-maintained laundry facility. Overall, this spot was good for an overnight stay before heading into Canada.
GuideLake Shel-oole Campground is a hidden gem in Shelby, Montana! This campground offers a plenty to do. There are baseball diamonds, a nice little dog run with a couple of obstacles, a fishing dock (although when we were here the lake water was pretty low) and biking trails.

Whether you're traveling in an RV or setting up a tent, the spacious sites provide comfort and convenience. It's an ideal spot.
TravelerGreat park. Good sites, full hookup, propane available, the best WIFI we've ever gotten in a rv park. Run by a very nice, competent couple.
ScoutWe spent two nights at this campground. Campground was quiet even for being in a railroad town. Hardly heard any train noise. Bathrooms appeared to get cleaned everyday. Sites have electric to them. Campground person came through every morning and talked to use. The local sheriffs office went through multiple times. Most water spickets did not seem to work so had to haul water from the spicket behind the RV dump station. This campground has issues with gophers and gopher holes. One camper got kicked out after six weeks of not paying while we were there according to the campground attendant. Lot cheaper than getting a hotel room at the cheapest hotel in town. Will stay again when we visit family in town.
RangerThe campground was mostly empty on July 3rd & 4th. A pay ($25 a night) station is on the honor system. Bathrooms and showers are old but in working order. A few sketchy looking campers here that look like from the movies breaking bad. If you know what I mean. Good for a night or two only.
