BLM vs National Forest Camping Rules Compared
· · By Inglehoff LLC
Key takeaways
- Neither agency has one national stay limit. BLM field offices set theirs by supplementary rule, and each National Forest sets its own by order; 14 days is the most common number on both, within a 28- or 30-day window.
- How far you must move after the limit, and how far you must camp from water, are set by each field office and forest, not nationally, so check the unit you will actually camp on.
- BLM manages roughly 245 million acres, concentrated in lower-elevation western desert, canyon, and open-range country; the Forest Service manages about 193 million acres across 154 forests, mostly mountain terrain.
- East of the Great Plains there is very little BLM land, so dispersed camping there is almost entirely a National Forest question.
- Fire restrictions are separate orders per agency, so check both if you are camping near an agency boundary.
Most free dispersed camping in the United States sits on land managed by two federal agencies: the U.S. Bureau of Land Management (BLM), with roughly 245 million surface acres, and the U.S. Forest Service (USFS), with about 193 million acres across 154 National Forests. Both treat what most campers call boondocking as a default right on most public land, yet the specific rules diverge in ways that decide whether your trip is legal. Stay limits, fire restrictions, permit zones, motorized-access regulations, and the statutory authority behind them all differ between the two agencies, and they differ again between individual forests and field offices. This guide lays the two rule sets side by side: how long you can stay before you must move, how far you must camp from water and roads, when seasonal fire orders override the defaults, and how each agency designates the routes you may drive to reach a site. It also explains how to tell which agency manages a given parcel, since the boundary is rarely marked on the ground, and where each agency publishes the current orders that govern it. Knowing the answer before you arrive prevents a citation or a trip that falls through at the trailhead.
Which Agency Manages Which Land?
As a general rule, BLM land is concentrated in the western states and tends to sit at lower elevation on open range, desert, and canyon country, while National Forest land wraps mountain ranges and covers most high-elevation terrain. East of the Great Plains there is very little BLM land at all, so dispersed camping there is almost entirely a National Forest question.
Colorado is a representative example of the split: approximately 8.3 million acres of BLM-managed land against 14.5 million acres of National Forest. BLM land there is concentrated on the western slope (Royal Gorge, Uncompahgre, Grand Junction, Glenwood Springs, and Kremmling Field Offices), the San Luis Valley, and pockets along the Front Range, while National Forest land covers the high country. For the forest-specific rules within Colorado’s 11 National Forests, see our dispersed camping rules by National Forest guide.
Both agencies publish interactive maps. For BLM: the BLM surface management maps. For USFS: USFS Region 2 (Rocky Mountain) maps page. On-the-ground, boundary markers and kiosks identify the managing agency, but downloading the relevant map before your trip is the reliable method. Once you know the road is USFS-designated, see how to read an MVUM to confirm your vehicle can legally use it.
How Do Stay Limits and Setback Rules Compare Between BLM and USFS?
Neither agency has one national stay limit or distance from water. On BLM land, 43 CFR 8365.1-2 bars camping longer than the authorized officer permits, and state or field-office supplementary rules set the days: 14 days within a 28- or 30-day period is common. On National Forest land, each forest sets its stay limit by order: 14 days in a 30-day period is common, though San Juan National Forest’s guidance says 16. How far you must move afterwards, and any distance from water, are set by the field office or forest.
| Rule | Bureau of Land Management (BLM) | U.S. Forest Service (USFS / NF) |
|---|---|---|
| Governing regulation | 43 CFR 8365.1-2 (no camping longer than the authorized officer permits), plus state or field-office supplementary rules | 36 CFR 261.58 (listed acts are prohibited where a forest order provides for them), plus each forest’s orders |
| Stay limit | Set by supplementary rules. 14 days within a 28- or 30-day period is common; how far you must move afterwards varies by field office | Set by each forest’s order. 14 days in a 30-day period is common, not universal (San Juan NF guidance says 16); how far you must move varies by forest |
| Distance from water | No national figure. Check the field office’s rules | No national figure. Set by forest order or guidance (Colorado’s forests alone publish 100, 150 and 200 ft) |
| Vehicle travel | Routes and areas designated in the field office’s travel management plan | Designated routes only (MVUM) |
| Campfire rules | Allowed except where a fire restriction is in force (check the field office) | Allowed except where a Stage 1 or Stage 2 restriction order is in force (check the forest’s alerts page) |
| Fire restriction authority | BLM issues its own restriction orders | The Forest Supervisor issues restriction orders, often at the same time as BLM |
| Group size | Varies by field office; groups and commercial use may need a Special Recreation Permit | Varies by forest; wilderness areas often cap group size |
| Permit requirements | Usually no permit for ordinary dispersed camping; check the field office | Usually no permit for ordinary dispersed camping; some wilderness areas require permits |
| Fee sites | Some BLM campgrounds charge fees; dispersed camping is usually free | Developed campgrounds charge fees; dispersed camping is usually free |
| Trash | Pack it out. No trash facilities in dispersed areas | Pack it out. No trash facilities in dispersed areas |
What Is the Key Practical Difference for Campers?
The most practical difference is who sets the rules and where you read them. On BLM land, stay limits and any distance from water come from the state office’s or field office’s supplementary rules. On National Forest land, they come from that forest’s orders. Both agencies most often use 14 days, but the window, the distance you must move afterwards, and the distance from water all differ from one unit to the next, so check the unit you will actually camp on.
The second difference is fire restrictions. BLM and Forest Service restrictions are often issued at the same time for an area, but they are separate orders, so National Forest land and the BLM land beside it can be under different restrictions. Check both if you are camping near an agency boundary.
“Camping on public lands … is generally free, but you must follow the rules and regulations for your specific area … including staying within designated areas for camping, and staying no more than 14 days.”

Where Can You Find Current Rules and Contact Information?
For BLM, start at blm.gov and select the state you are heading to; each Field Office contact is listed on its state page. For USFS, each region publishes an alerts index (for example fs.usda.gov/alerts/r2 for the Rocky Mountain Region) and each forest’s home page carries its own orders. The Camprtron site marks each dispersed site with its managing agency and links to the relevant area manager page directly from the site detail view; see our data coverage page for what is mapped and reviewed in each state, and the Colorado access road analysis for how road access breaks down across both agencies’ land in that state. Where a forest order narrows the federal rules described here, it is tracked in where dispersed camping is restricted, and the state half of the question, which follows no federal pattern at all, is answered in dispersed camping on state land, state by state.
