How long you can stay
The whole point of the camp card is to answer how long can you live here. But it's answering the supply half of that question — how many days your water, tanks, propane and food last — and there's a second half it can't look up for you: how long you're allowed to stay. Those two clocks are different, and the legal one changes from one patch of ground to the next. This note is the legal half, kept short and honest: what the number on the card really means, the rough shape of the national-forest and BLM rules, and — the part that actually matters — how to find your unit's limit before you lose signal. The numbers below are the usual pattern for free, dispersed camping on national forest and BLM land; national parks, monuments, and state land run on their own rules, so treat those the same way you'd treat any unit here — look up that specific place. One thing up front, because it's a legal topic: I'm a camper writing down how this works in the field, not a lawyer, and nothing here is legal advice. The rule that governs your stay is the one written in that unit's order and posted on the ground.
The card's ~14 days is a round guess, not your unit's rule
Start with the number you're already looking at. When your supplies would last a long time, the autonomy card stops counting at about fourteen days and tells you plainly: "about 14 days — check your unit for the real limit." Read that ~14 for exactly what it is: a round planning assumption so the math doesn't pretend you can homestead a spot forever — not the legal stay limit for your exact ground. It can be wrong in both directions. Your unit might be shorter than fourteen days — a busy area, a drought or fire order, a seasonal closure — in which case the card is quietly showing you more legal days than you actually have. Or you might be allowed to stay longer, with a permit (more on that below). The card does tank math; it doesn't read your forest's order. So treat its ~14 as a ceiling to plan against, and go find the real number. More on what the card does and doesn't know in reading your camp page.
National forests: usually about 14 days in a 30-day window — but the forest's order is the rule
Most national forests cap dispersed camping at around fourteen days within any thirty-day period — and that "around" is doing real work, so don't hang a long trip on it. Each forest sets its own limit by a written order, which means it genuinely varies from forest to forest: some make you leave the forest entirely for a couple of weeks before you can camp again, some cap how many total days you can camp there across a year, and some high-use spots are shorter than fourteen. The number you saw on a blog — or on this page — is not authority. Find this forest's rule: look on its website for alerts, closure or occupancy orders, and the recreation or camping pages; check the travel information that comes with the motor vehicle use map; or read what's posted at the ranger district office. When they disagree, the posted order wins.
BLM: commonly about 14 days, and then you actually move
On BLM land the common shape is about fourteen days within a twenty-eight-day period, and when you reach it you're expected to genuinely move on — often a real distance, on the order of twenty-five miles from where you were, and not circle back to the same spot for a while. It is not "pull forward to the next pullout and reset the clock." Like the forests, the exact day count and the move rule are set by the local field office and can differ from the rough numbers here, so if a longer stay is your plan, check that field office's camping page or call ahead rather than assuming. The point of the move isn't to inconvenience you — it's to keep any one rig from settling into a shared spot.
The exceptions run both ways — permits and long-term areas
If you want to sit in one place longer than the limit, the honest path is a permit, not quietly overstaying and hoping. The clearest example is on BLM land: the agency runs a handful of Long-Term Visitor Areas in the California and Arizona desert where winter travelers can stay for months at a stretch on a paid seasonal permit. Those are specific, signed places with their own rules — a real option, but not a loophole you can apply to any pullout. Developed campgrounds are their own world too: they post their own stay limit at the entrance — often around fourteen days, sometimes shorter, sometimes longer — and that posted board is the rule there, separate from the dispersed limits above. If a page here is a developed or fee campground, expect the on-site sign, not this note, to set your clock.
Why the limit exists, and what enforcement looks like
This isn't red tape for its own sake, and it helps to understand why so you'll actually keep it. The stay limit keeps one rig from turning a shared dispersed spot into a permanent camp, it gives the ground time to recover between users, and it's a real part of why free dispersed camping stays open at all — the alternative to "everyone moves along" is "the agency closes the area." A ranger or field officer can, and does, ask how long you've been parked; overstaying can get you a friendly heads-up, a move-along, or a citation, and there's genuine discretion in how any of that goes. Staying on the right side of it is simple and it's on you: know the unit's limit before you settle in, keep track of your own days, and pack up and move when your time's up — without being asked, because the next person gets to use the spot too. That's the same ethic as the rest of the site; more of it in leave no trace.
How to actually find your limit before you lose signal
Because the number changes unit to unit, look it up while you still have bars — signal dies past the cattle guard, and there's no help coming from your phone once it does. Before the pavement ends, check the managing unit's own website — the specific national forest or the BLM field office that covers your spot — along with any alert or order posted there, and screenshot it so you've got it offline. When you arrive, read the kiosk or the sign at the entrance: a posted number beats anything you read at home. If you genuinely can't find the rule, the safe move is to treat fourteen days as a hard ceiling, not a promise, plan to move sooner, and ask a ranger or the district office — they would much rather tell you the limit than write you up for missing it. Working this into your first-night routine is covered in your first dispersed night.
The honest close, same as all of these: the tools on this site help you plan a stay, they don't set the rules for one. The autonomy card is tank math capped at a round ~14 days — it doesn't read your forest's order, and it can't tell whether your exact spot is a five-day area, a normal fourteen-day area, or a permit area. The services map draws straight-line distances, not the drive. The weather strip is a broad area forecast. The one thing that actually governs how long you can stay is the unit's posted order and the officer who can point at it — so look it up, track your days, and move on when it's time. And again: this is field practice, not legal advice.
