    Rosewill RV Park

    Nice , quiet place

      We have stayed here twice, once 2 years ago for 2 mo. and then again for the month of August this year. Level sites, good water, 30 & 50 amp service & city sewer. TV is over the air, 6 ch, if the weather permits so bring a few DVD's.  A nice quiet place. There are no facility's, like shower house or bathroom's.

      You are 3 blocks from downtown, so within walking distance of every thing in town. The park does not have wi-fi, however, the public library  does have free wi-fi.

     A word of warning, unless you have Verizon  or Nemont phone service your phone will not work!   The owner of the park lives off site, is only a phone call away & is a very nice guy !

    Trenton Lake Recreation Area

    Very Basic, Looks to be Poorly Staffed

    In the main camping area, about 20 sites with generally level concrete pads, but close together with no screening between sites.  Several campsites had trailers but no occupants.  Camping area is across from the boat ramp to the lake, but does provide decent lake views.  Posted price of "full hook-up" was $35.  Hmmm.  Electricity, yes, but no sewer connection that we could find and (despite faucets) several signs declaring "non-potable water." Scattered picnic tables (no table at many sites).  Bathrooms locked and unavailable.  Some of this might have been sorted by staff members, but no one appeared from the time of our arrival till the time of our departure (pay envelopes and a slot).  Although June 30th, the place had the feeling of not being open for the season.

    Bruegger Centenial Park

    Price is right

    Nice place to stop for the night, no designated sites but I set up a pop up in the parking lot and it worked great. Two blocks off of Hwy 2, restrooms available but not showers. It may be a little close to active  railroad tracks for a light sleeper.

    Brush Lake State Park Campground

    Small campground overlooking lake

    Campground is set on top of hill overlooking Brush Lake which is a gem in itself. Campsites are spacious, but no trees for privacy or shade. There are bathroom facilities. Trails that lead down to the lake. Lake has restroom facilities, picnic tables, boat ramp, and beach area. The lake was a hidden gem among locals, so not a ton of people camping. One side of the lake is a state park and the other is privately owned.

    Blacktail Dam

    Nice Place

    All camp spots are right on the water, though most of them have cat tails and thick vegetation making it difficult to get to the water. Each site has electric that you share with your neighbor. They have a water station, dump station, showers that could use some attention, they have a nice playground for the kids, some picnic shelters, bathrooms and garbage cans. We stayed over the 4th so it was very busy but still enjoyable (coming from a family that prefers our solitude). There isn't a lot of water access for shore fishing and swimming is prohibited in most areas. There is a swimming beach about 1.5 miles from where we had camped which was pretty central to the grounds. It's not a big beach area so busy days it can be a little crowded. It is nice and sandy and great for the kiddos, though. All in all, the campground was nice and I would stay again!

    Brush Lake State Park Campground

    Warm lake, not crowded

    Went here deliberately because it is not extremely busy and has a warm lake for swimming, boating, tubing. Canoing that is very near the campground. Fantastic restaurant in Genora, ND about 5 miles away. Went in late July and flies were somewhat bothersome. But lake was so refreshing and this would make a perfect 1-2 day stop between many locations in MT and ND. 27 miles to Canadian Border. Went swimming every day I was there except one day when it was cool. 150 miles to Theodore Roosevelt National Park which was also great.

    Trenton Lake Recreation Area

    Basic campground

    Large campground area. Fire pits, large camp spots but close together. Two small cabins . Beds only. Small store. Lake. But most of the time it isn't clean enough to swim or fish in.

    Blacktail Dam

    Can get busy!

    It's a smaller lake with housing all around it. Around the 4th of July can get super busy. They keep the facilities clean!

    Blacktail Dam

    Popular area

    Blacktail Dam is a popular destination for most area people. It is a small dam so it does tend to get quite busy, with minimal camping spots. Most of the land around the lake is privately owned lots.


Guide to Dagmar

RV camping near Dagmar, Montana offers basic amenities with limited seasonal availability. The northeastern Montana region experiences temperature extremes with summer highs reaching 90°F and winter lows dropping well below freezing. Most campgrounds in this rural area maintain minimal facilities with electric hookups being the most common utility available to campers.

What to do

Fishing opportunities: At Blacktail Dam, visitors can access multiple fishing spots directly from campsites. "Decent fishing for pike, walleye and sunfish. We haven't camped here yet, but I would love too. We go out fishing for day trips," notes Kori P. The shoreline access varies between sites due to vegetation growth.

Playground access: Families camping at Blacktail Dam can utilize the children's play area. "They have a nice playground for the kids, some picnic shelters, bathrooms and garbage cans," reports Leah N., who camped there during a busy holiday weekend.

Downtown exploration: Staying at Sheridan County Fairground puts campers within walking distance of Plentywood's downtown area. "Nice little campground. Has electric and water. Just down from rest area in Plentywood MT," according to James R., who found the location convenient for accessing local services.

What campers like

Shaded sites: The tree cover at Sheridan County Fairground provides relief during hot summer days. James R. describes it as "Nice shady in amongst some Cottonwood trees. Came in real handy in the middle of nowhere."

Free camping options: Bruegger Centennial Park offers no-cost camping with basic amenities. "Free city campground with restrooms, water hydrant, dump station, and picnic tables. Residential area in town. Quiet neighborhood," reports Luckybreak R.

Waterfront sites: Many campsites at Blacktail Dam feature water views. "All camp spots are right on the water, though most of them have cat tails and thick vegetation making it difficult to get to the water," explains Leah N. who details the varying quality of shore access between sites.

What you should know

Railroad proximity: Noise from nearby train tracks can disturb light sleepers at some campgrounds. At Bruegger Centenial Park, Shawn W. notes it "may be a little close to active railroad tracks for a light sleeper," despite being an otherwise convenient stopover location.

Service limitations: Cell phone coverage remains restricted throughout the region. Different campgrounds support different carriers, with minimal options available. Many campgrounds lack WiFi connections, though some towns offer public access points.

Bathroom availability: Restroom facilities vary widely between campgrounds. "The bathrooms aren't open and the water is not on yet so we'll probably head over to a state park instead," reports Teresa T. about spring camping at Blacktail Dam, indicating seasonal facility closures.

Tips for camping with families

Beach access: Blacktail Dam includes a swimming area for children, though its size limits capacity during busy periods. "There is a swimming beach about 1.5 miles from where we had camped which was pretty central to the grounds. It's not a big beach area so busy days it can be a little crowded. It is nice and sandy and great for the kiddos," notes Leah N.

Seasonal activity planning: Many family-friendly amenities close during off-season months. "Everything was closed I'm here in April so I would have been the only camper had I stayed," explains Teresa T. about visiting Blacktail Dam early in the year, suggesting families confirm facility availability before arrival.

Privacy considerations: Campgrounds near residential areas may feel less secluded. "I don't like all the houses out here. It makes you feel like you are constantly being watched," explains Kori P. about camping at Fox Run RV Park, where nearby homes border the recreation area.

Tips from RVers

Electric hookup sharing: At Blacktail Dam, adjacent sites share electrical connections. "Each site has electric that you share with your neighbor," notes Leah N., suggesting campers bring extension cords and power strips when electrical needs exceed standard usage.

Advance verification: Calling ahead prevents arrival at closed campgrounds. "We arrived but the gate was locked. We walked to the camping spots and it looks like it would have been a great place to stay," reports Nita H. about her experience at American Legion Park, which was unexpectedly closed.

Level site availability: Several campgrounds offer flat parking surfaces suitable for RVs. "Level sites, good water, 30 & 50 amp service & city sewer," writes Wendell V., detailing the practical benefits for larger vehicles at certain locations.
