American public land is not one system. It is several agencies holding different ground under different law, and the one whose land you are parked on decides what you may do there. Getting the acronyms straight is not trivia for an overseas visitor: it is the difference between a legal free night and a citation.
Here is the soup, in the order it will matter to you.
BLM: Bureau of Land Management
The agency nobody outside the United States has heard of, and the one most associated with free camping.
The BLM manages 245 million acres of public land, which it describes as “one in ten acres in the country,” plus 700 million acres of mineral estate. Its stated mission is “to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations,” and it manages “for multiple-use,” which is why you will meet grazing, mining and recreation on the same landscape.
For a camper, the BLM’s own summary is the clearest statement of the American default: camping “on public lands away from developed recreation facilities is called dispersed camping,” and “most areas don’t require permits or reservations.” It notes that “some regions may require permits for large groups or campfires.”
Then the qualification that governs everything else it says: “rules can vary by state or local area, so always comply with posted signs and verify specifics with your local BLM office.”
The BLM also runs developed campgrounds. Those are a different proposition: “some BLM campgrounds charge a fee, which helps maintain facilities and visitor services,” and where there is a fee you “pay the required fee within 30 minutes of occupying a site.”
Where the BLM is: its regional offices are Alaska, Arizona, California, Colorado, Eastern States, Idaho, Montana and the Dakotas, Nevada, New Mexico, Oregon and Washington, Utah, and Wyoming, with headquarters in Grand Junction, Colorado and in Washington, DC. Eleven of the twelve name western states. That list is effectively the map of where this style of camping is realistic.
USFS: the US Forest Service
The Forest Service sits in the Department of Agriculture, not the Interior, and manages the national forests and grasslands. In practice it is the second great venue for dispersed camping in the west, and its rules are set forest by forest and ranger district by ranger district rather than nationally.
Get the stay limit, the distance rule, the campfire permit requirement and the fees from the ranger district office for the forest you are actually going to. That office is also the only body that can tell you about current closures on its roads. Numbers for national forests circulate widely online, and what is usually circulating is one district’s rule repeated as if it were national.
Recreation.gov confirms the Forest Service is one of the two agencies most associated with dispersed camping, and that the answer varies by landlord: “depending on the public land managing agency … dispersed camping is not allowed, and sometimes it is.”
NPS: the National Park Service
The famous one, and the one where the permissive default does not apply.
National parks run on designated campgrounds and on permits. The Park Service’s general instruction to anyone planning a night out is to “check ahead of time about any necessary permits and park regulations,” and those regulations are written park by park, not nationally.
Two examples, chosen because they show how differently two parks can answer the same question:
At Shenandoah, in Virginia, “a backcountry camping permit is required to camp in Shenandoah’s backcountry.” Camping is then permitted at pre-existing sites, subject to a long list of setbacks: at least 10 yards from a stream or other natural water source, 20 yards from any park trail or unpaved fire road, 50 yards from another camping party, and a quarter mile from any paved road, park boundary or park facility. Named areas including the Old Rag and Hawksbill summits are closed to overnight camping outright.
At Lassen Volcanic, in California, “a wilderness permit is required to camp in park’s backcountry (outside of park campgrounds),” and “permits may only be obtained online through recreation.gov.” The park states there are “no designated backcountry campsites within the park, but there are areas closed to backcountry use,” and it sets its own setbacks: outside half a mile of developed areas or park roads, 100 feet from water, a quarter mile from hydrothermal areas.
Same agency, two different regimes, both requiring paperwork before you sleep. Neither is a place to turn up and pull over. Plan a national park visit as a booking.
The rest of the federal landlords
Recreation.gov lists 12 federal participating partners: the Bureau of Land Management, Bureau of Reclamation, Bureau of Engraving and Printing, Federal Highway Administration, National Archives and Records Administration, National Oceanic and Atmospheric Administration, National Park Service, Smithsonian Institution, Tennessee Valley Authority, Fish and Wildlife Service, US Army Corps of Engineers, and US Forest Service.
The one a camper meets is the US Army Corps of Engineers, which manages recreation around reservoirs across a lot of the country including the east. Call the office that manages the lake before you plan a night on it.
State parks are a separate country
Every state runs its own park system, under its own law, with its own fees and its own reservation platform. A state park is not a small national park and the National Park Service has nothing to do with it.
There are 50 systems and they do not agree with each other, so check the state’s own park agency and plan the night as a booking.
Why there is no list of dispersed sites
Dispersed camping in America mostly happens on ground nobody designated for it, which is the whole point of the model: the permission is general, so there was never a spot to name. That is why you will not find an official register of places to pull off, and why the incumbent American apps run on pins submitted by other travelers rather than on anything an agency published.
What that means on the road is that the useful research is not “find the list”, it is “find out who manages this ground and what they have closed”. A current map from the field office beats any list.
For the rig, not the land
Tanks, power, leveling, what size rig a forest road will take, and state-by-state overnight parking are all covered on our sibling site, Boondock Maps.
The sign wins
Every agency above ends its own guidance the same way, and so do we. The posted sign and the current word from the local field office, ranger district or park beat this page. Fire restrictions in particular change week to week, and a page cannot keep up with them.
Start with free camping in the USA: how it actually works, then stay limits on US public land. The country overview is at United States, and the European model you are probably arriving with is at free camping in Europe.
