Montana has some of the most permissive and accessible dispersed camping in the country. The state contains 17 million acres of national forest land and millions more BLM acres, all with the standard free dispersed camping framework: no reservation, no fee, 14-day limit. Montana's rules are simpler than California or Oregon's - no state campfire permit system, no pass requirements for most dispersed camping access. The main thing to prepare for differently here is wildlife - specifically grizzly bears in the northwest and black bears statewide.
Montana's national forests: the main option
Montana has 10 national forests spread across the western mountains and eastern front. All allow dispersed camping under standard Forest Service rules. The western forests sit in the Northern Rockies - dramatically different terrain from the eastern front rangeland forests near Billings and Great Falls.
Gallatin National Forest (Bozeman area)
One of the most popular Montana forests, surrounds Bozeman and covers terrain from the Yellowstone border north. The Paradise Valley south of Livingston along the Yellowstone River has BLM and national forest land with dispersed camping. Hyalite Canyon south of Bozeman (FR 62) has developed camping but dispersed sites exist on surrounding forest roads. High-clearance recommended for most forest road access. Season: June through October. This is grizzly country - bear canisters or bear hang systems required. Bear spray is mandatory, not optional.
Flathead National Forest (Kalispell / Whitefish area)
Northwest Montana's primary national forest, bordering Glacier National Park on the east. The Bob Marshall Wilderness Complex - one of the largest roadless wilderness areas in the lower 48 - is within the Flathead NF. Dispersed camping on forest roads throughout the non-wilderness portions. The Swan Valley (Hwy 83 corridor) has multiple dispersed sites along forest roads. This is the core of Montana grizzly bear country - treat food storage as mandatory, not advisory. Season: June through October at higher elevations; some valley roads accessible May through November.
Bitterroot National Forest (Hamilton area)
Western Montana along the Idaho border, south of Missoula. The Bitterroot Valley and the mountains east of Hwy 93 have extensive forest road dispersed camping. The West Fork Bitterroot area (FR 73 west from Darby) has multiple established dispersed sites in a river corridor at 4,000 to 6,000 feet. High-clearance recommended. Season: May through October. Black bears active statewide; grizzlies possible in northern sections near the Selway-Bitterroot Wilderness.
Custer Gallatin National Forest (Billings / Miles City area)
Eastern Montana's primary national forest, covering the Beartooth and Absaroka Ranges plus eastern Montana breaks terrain. The Beartooth Highway (US-212) corridor near Red Lodge gives access to some of the highest dispersed camping in Montana at 8,000 to 10,000 feet. Eastern portions are more prairie and breaks terrain - very different from western Montana. The eastern sections have lower precipitation and fewer regulations. Season: July through September at high elevations; lower eastern areas accessible May through November.
BLM land: eastern Montana's option
Montana's BLM land is concentrated in the eastern part of the state - the short-grass prairie, badlands, and river breaks east of the Rocky Mountain Front. The Missouri River Breaks National Monument northeast of Lewistown is the premier BLM dispersed camping area in Montana, covering dramatic badlands and the Missouri River corridor along US-191.
Standard BLM rules apply: 14-day stay in any 28-day period, relocate at least 25 miles. Eastern Montana BLM land is much drier than western forests - fire restrictions apply in dry summers. The terrain is more open and accessible by 2WD than most western Montana forest land. Season: April through November. Black bears are less common in eastern Montana than the west; rattlesnakes are more common in eastern badlands terrain.
Grizzly bear protocols for Montana camping
Western Montana - essentially everything west of the Continental Divide plus the front ranges near Glacier and Yellowstone - is active grizzly bear habitat. Grizzly protocols are different from black bear protocols and need to be treated seriously.
- Bear spray. Carry it in a hip holster, accessible within seconds. Not in your pack. Studies consistently show bear spray is more effective than firearms in preventing injury in grizzly encounters. Every adult in your group should carry a can. EPA-approved bear spray with a minimum 7.9 oz capacity and 1-2% capsaicin concentration.
- Food storage. Hard-sided bear canister or certified bear-resistant container required in some Montana wilderness areas. Check the specific ranger district orders. Even where not required, hang food at minimum 10 feet off the ground and 4 feet from the hanging tree in a stuff sack - not in a bag that has food smell, not in your tent. Never sleep with food or cooking odors on clothing.
- Camp layout. The classic triangle: sleep at least 200 feet from your cooking area and 200 feet from your food storage location, with all three points 200 feet apart from each other.
- Make noise. Talk loudly, clap, or use a bear bell on the trail to your campsite. Surprise encounters are the primary cause of grizzly attacks.
- Black bears statewide. Montana also has black bears in all forested areas. The food storage and camp layout rules apply statewide, not just in grizzly zones.
5 specific Montana free camping areas
1. Gallatin NF / Paradise Valley BLM (Park County)
Access: US-89 south from Livingston through Paradise Valley. BLM and national forest land on both sides of the valley with dispersed camping. East side forest roads (off East River Road) access dispersed sites in the Absaroka Range foothills. High-clearance recommended. Season: May through October. Grizzly and black bear country - full bear protocols required. Livingston is 20 minutes north for supplies.
2. Flathead NF / Swan Valley (Lake and Missoula Counties)
Access: Hwy 83 south from Bigfork through the Swan Valley. National forest land on both sides of the Swan River with dispersed camping on forest roads off the main highway. FR 80 (Holland Lake Road area) and several other forest roads access dispersed sites at 3,500 to 5,500 feet. High-clearance recommended. Season: June through October. Core grizzly country - bear spray mandatory. Holland Lake is a stunning turquoise lake with easy dispersed access on surrounding forest land.
3. Bitterroot NF / West Fork (Ravalli County)

Montana dispersed camping rules
- Stay limits. National forests: 14-day limit, must move. BLM: 14 days in 28-day period, relocate 25 miles. No state campfire permit system (unlike Oregon or California).
- Fire restrictions. Check the specific ranger district website and the Montana DNRC (dnrc.mt.gov) for current restrictions. Montana fire seasons are increasingly severe in August and September.
- Water. Filter all stream and lake water - Giardia is present in Montana backcountry water. Sawyer or MSR filter required.
- 200 feet from water. Required on all national forest and BLM land.
- Wilderness areas. Bob Marshall, Selway-Bitterroot, and Absaroka-Beartooth Wilderness areas require free self-registration permits at trailheads. Dispersed camping on forest roads outside wilderness boundaries has no permit requirement.
