Flathead Lake dominates the Big Arm region with 200 square miles of crystal-clear water surrounded by forested mountains. Most camping areas in the Big Arm area operate between May and late September, with summer temperatures averaging 75-85°F during the day and dropping to 45-55°F at night. Some campgrounds remain open year-round with limited amenities during winter months.
What to do
Boat to Wild Horse Island: Access Big Arm State Park's dock for a short boat ride to this day-use only island. "Wild Horse island in Flathead Lake is incredible, absolutely worth the trip (by boat only)," notes Justin S. from Big Arm State Unit — Flathead Lake State Park.
Winter camping access: Whitefish Lake State Park remains accessible year-round for those seeking yurt camping near Big Arm, Montana during winter months. "This is probably one of the best places to camp to get out to Whitefish to ski," shares Evan H. from Whitefish Lake State Park Campground.
Hot springs soaking: Wild Horse Hot Springs offers multiple private soaking pools at $14 per person (in addition to camping fees). "They have a huge variety of separate pools to choose from. Beautiful views all around," mentions Melita B. from Wild Horse Hot Springs.
Paddleboard rental: Rent affordable paddleboards directly at some campgrounds rather than bringing your own. "You can rent paddle boards right at the campground for a very affordable price," says Maddy D. about water recreation options.
What campers like
Yurt accommodations: Big Arm State Park offers yurts as alternative lodging options. "These circular traditional structures are an experience not soon forgotten by kids or adults alike," shares Kent B. about his yurt camping experience at Big Arm.
Lakefront camping: Sites directly on Flathead Lake provide immediate water access. "Camped in one of the spots that is right on the lake and could get in the water easily. Water is really clear," explains Olivia J. from Rollins RV Park.
Community atmosphere: Some campgrounds foster social interaction through shared spaces. "They also have fire pits available that you can use. Nice park for the kids to play," shares Brett T. about the community areas.
Swimming areas: Dedicated swimming spots keep boaters and swimmers separated. "We enjoyed a very lazy day hanging out, reading and swimming," says Stephanie S., describing the relaxed lake access.
What you should know
Train noise considerations: Some campgrounds near railroad tracks experience regular train disturbances. "Trains pass through regularly, all night long. It was so close that our tent shook!" warns Emily F. about noise levels at certain locations.
Early reservations required: Flathead Lake campgrounds fill quickly during summer months. "Spots were booking up quick around the lake," notes Brett T., emphasizing the need to reserve well ahead, especially for holiday weekends.
Shower costs vary: Some campgrounds charge for shower use. "Showers are $3 for 6 minutes," mentions Olivia J. about facilities at Rocky Mountain Hi Campground, where they also note the "huge laundry facility" for campers needing to wash clothes.
Seasonal availability: Most yurt camping opportunities near Big Arm operate seasonally. "Swan Lake Trading Post & Campground has yurts that had not been set up for the season during our visit," notes Dexter I., indicating the importance of checking seasonal availability.
Tips for camping with families
Dog-friendly options: For families traveling with pets, dedicated pet areas enhance the experience. "Great dog park, kids area, wonderful fire pits! Staff was kind and helpful," describes Brian C. from North American RV Park & Yurt Village.
Playground access: Campgrounds with play equipment provide entertainment for children. "Great place to camp with children because of the large, grassy playground and swimming area," recommends Kimberly Y. about facilities for younger campers.
Kid-oriented activities: Some campgrounds offer structured recreation. "The kids could play all day in the great park with a whole western town set up and swimming hole in the creek, volleyball net and paved roads to scooter and roller blade," shares Jennifer H. about the variety of activities.
Safety considerations: Some campgrounds have installed protective measures. "My wife really enjoyed the fact that it had an electric fence around the perimeter to try and preclude wildlife from entering the park area," notes andrew from West Glacier KOA Resort, providing peace of mind for families concerned about wildlife.
Tips from RVers
Site selection strategy: Corner sites often provide more privacy in busier campgrounds. "We got a prized corner spot with privacy of trees. So nice to have a grassy site, too," recommends Melody C. about selecting optimal locations.
Honesty system amenities: Some parks offer after-hours access to supplies. "Loved how they use honesty policy during closed hours where you can pick up firewood or ice and pay the next morning," shares Danielle F. about convenient services.
Utility considerations: Not all sites offer full hookups. "Full hookups, picnic bench, recessed firepit," notes Sandy G. from Glacier Campground, listing the amenities that matter to RVers.
Length restrictions: Larger rigs may not fit in all campgrounds. "Big, flat spots" are available at Big Arm State Park's B loop, according to Nicki A., who also notes that "a couple of walk-in sites [were] still available at 3 pm on a Saturday in late June."
