Yes — federal law allows firearms in national parks, but with important conditions. As of February 2010, carrying a gun in a national park is governed by the law of the state in which the park sits. If you have a valid permit in that state — or if that state allows permitless carry — you can carry on most national park land.
However, firearms are prohibited inside federal buildings and visitor centers regardless of your permit status, and discharging a weapon remains illegal except in genuine self-defense. Here is everything a carrier needs to know before the trip.
The 2010 Law That Changed Everything
Before February 22, 2010, carrying a firearm in a national park was heavily restricted. Federal regulations required that any gun brought into a national park be unloaded, cased or disassembled, and stored — functionally inaccessible.
Carrying a loaded firearm for self-defense, even with a valid state concealed carry permit, was a federal violation.
That changed through an unlikely vehicle. The Credit Card Accountability Responsibility and Disclosure (CARD) Act of 2009 included an amendment sponsored by Senator Tom Coburn that rewrote the federal regulation on park firearms.
The amendment, codified at 54 U.S.C. § 104906, replaced the blanket restriction with a rule that defers to state law. Congress specifically tied park carry rules to existing state permit frameworks rather than creating a separate federal permit system.
The practical result: national parks are no longer a special legal category that suspends your carry rights. They operate under the same framework as the rest of the state you're standing in — with one significant and universally misunderstood exception.
How the Rules Actually Work — State Law Governs Your Permit
Under 54 U.S.C. § 104906, the lawfulness of carrying a firearm in a national park is determined entirely by the law of the state in which the park is located. This means your home state permit is not automatically valid. What matters is whether your permit — or your permit-free carry status — is recognized by the park's host state.
Which State's Laws Apply?
The answer sounds simple until you look at a map. If you are in Grand Canyon National Park, Arizona law applies. If you are in Acadia National Park, Maine law applies. If you are in a park that crosses state lines, the law of whichever state you are physically standing in at that moment governs your carry eligibility.
Several major parks span two or three states. Great Smoky Mountains National Park straddles Tennessee and North Carolina — two states with different permit laws and different reciprocity agreements. Yellowstone National Park covers land in Wyoming, Montana, and Idaho.
A multi-day backcountry trip that crosses from Wyoming into Montana means your carry status potentially changes mid-trail, depending on your home state's reciprocity agreements with each state. Before any cross-state-line park visit, verify your permit's recognition in every state whose land the itinerary covers.
Open Carry vs. Concealed Carry in National Parks
Whether open carry or concealed carry is permitted follows the same state-law rule. If the state where the park sits allows open carry without a permit, you can open carry in that park. If the state requires a permit for concealed carry, you need that permit. If the state prohibits open carry, that prohibition extends into the park.
This means the rules vary significantly by park location. A visitor to Big Bend National Park in Texas can open carry without a permit on park trails, consistent with Texas law. A visitor to Shenandoah National Park in Virginia operates under Virginia's carry laws. There is no single national park carry standard — the standard is always the host state.
Where You Cannot Carry — The Federal Building Exception
This is the rule that catches the most carriers off guard, and it applies everywhere without exception: firearms are prohibited inside federal facilities, regardless of state law, regardless of your permit, and regardless of which national park you're in.
The authority for this prohibition is 18 U.S.C. § 930, which makes it a federal offense to knowingly possess a firearm in a federal facility — defined as any building owned or leased by the federal government where federal employees regularly work.
Visitor Centers
Every national park visitor center is a federal facility. The moment you step through the door, your permit does not protect you. This catches hikers who stop to pick up a trail map, families checking in on the first morning, and experienced carriers who don't think twice about the building they're entering.
The firearm must be secured before you go inside — not handed off to someone outside, not tucked under a seat as an afterthought, but secured in a locked container in your vehicle.
Ranger Stations and Administrative Buildings
Any building staffed by park rangers or administrative personnel qualifies as a federal facility. This includes backcountry permit offices, maintenance facilities, and staffed entrance booths in some configurations.
Park Concession Buildings
Lodges, restaurants, and other concession facilities operating within national parks under federal contract are generally also subject to the prohibition when located in federally owned buildings.
Check for posted signage — 18 U.S.C. § 930(g)(3) requires that federal facilities be posted with notice of the prohibition — though the absence of a sign does not eliminate the legal restriction.
What to Do with Your Firearm at a Visitor Center
This practical question goes completely unanswered on competing pages. You have a few lawful options.
First, if you drove to the trailhead, secure the firearm in a locked container in your vehicle before entering any federal building — a locked glove box or dedicated lockbox satisfies this requirement, and a firearm in a privately owned vehicle in a federal parking lot is not prohibited by 18 U.S.C. § 930.
Second, if you're on foot with no vehicle access, plan your route so that visitor center stops happen before you strap up for the trail, or after you return. Entering a visitor center while armed is not a gray area — it is a federal offense with penalties up to one year imprisonment for a first offense.
Discharging Firearms — What's Always Prohibited
The right to carry in a national park does not include a right to fire. 36 CFR 2.2 prohibits the discharge of a firearm in a national park except in specific circumstances — primarily genuine self-defense.
This regulation exists independently of carry authorization; even a lawfully armed visitor may not discharge their weapon for target practice, pest control, or any other reason outside a genuine defensive necessity.
Hunting is separately and explicitly prohibited in national parks under the same regulation.
The carry rule that took effect in 2010 changed nothing about hunting — national parks remain no-hunting zones. National forests, BLM land, and national recreation areas have separate, generally more permissive rules on both discharge and hunting.
This is a distinction that matters: carrying ≠ hunting authorization. A firearm carried legally on a park trail for personal protection does not become a hunting tool by virtue of the carrier's permit. Any discharge that does not qualify as self-defense is a violation of 36 CFR 2.2.
National Parks vs. Other Federal Lands
"National park" is not a catch-all term for federal outdoor land, and the rules vary significantly across federal land management categories. This chart covers the most common land types a visitor might encounter:
| Federal Land Type | Agency | Carry Allowed? | Permit Required? | Discharge Allowed? |
|---|---|---|---|---|
| National Parks | NPS | Yes (state law applies) | Depends on state | No (except self-defense) |
| National Forests | USFS | Yes | Depends on state | Yes (where designated) |
| BLM Land | BLM | Yes | Depends on state | Yes (where designated) |
| National Wildlife Refuges | USFWS | Yes (state law) | Depends on state | Limited (hunting seasons) |
| National Recreation Areas | NPS / USFS | Yes (state law) | Depends on state | Varies by unit |
| National Monuments | NPS / BLM | Yes (state law) | Depends on state | Varies by managing agency |
| Federal Buildings (any land) | GSA / NPS | No | N/A | No |
National forests managed by the U.S. Forest Service operate under more permissive rules than national parks. Shooting ranges exist within some national forests, target shooting is permitted in designated areas, and hunting is broadly allowed during state-regulated seasons.
If your route transitions from a national park into an adjacent national forest — a common occurrence in the Mountain West — your carry status doesn't change, but the discharge rules do.
BLM land is similarly more permissive. Large swaths of the American West are BLM-managed, and most of it allows target shooting in dispersed areas not near campgrounds or developed facilities.
When mapping a trip that combines national park land with adjacent BLM or forest land, identify which land management category you're in at each stage.
The Gun-Free School Zones Act — The Gap Nobody Talks About
This is the most legally significant point in this entire article, and none of the five top-ranking pages on this topic address it. If you carry under your state's permitless carry law rather than a formal state-issued license, you need to read this carefully.
The Gun-Free School Zones Act (GFSZA), codified at 18 U.S.C. § 922(q), makes it a federal felony to knowingly possess a firearm within 1,000 feet of a school zone. The law includes an exception at 18 U.S.C. § 922(q)(2)(B)(ii) for individuals licensed by the state to carry a firearm — but that exception specifically requires a state-issued license. It does not extend to permitless carry.
This matters in national parks because some parks contain or are adjacent to developed communities with schools inside or near park boundaries. The 1,000-foot GFSZA radius can extend across roads, parking areas, and trails.
A carrier relying on permitless carry authorization — rather than a formal CCW license — who passes through a GFSZA-covered zone is exposed to federal felony liability that their state's permitless carry law does not protect against.
The practical takeaway for permitless carriers: If you carry under your state's constitutional carry law and do not hold a formal CCW license, obtain a state-issued license before carrying in or near any developed area within a national park.
The licensing exception in the GFSZA is the only protection available, and that protection requires a license. Permitless carry does not satisfy it.
This is not a remote hypothetical. Carrier prosecutions under the GFSZA are uncommon, but the exposure is real and the defense against it is simple: get licensed.
Park-Specific Rules You Need to Check Before You Go
While 54 U.S.C. § 104906 establishes the state-law framework, individual parks may have additional rules on top of it — particularly regarding specific facilities, events, and areas within the park boundary.
Some parks contain school zones (see above). Some contain tribal land inholdings where NPS regulations do not apply and tribal law governs. Some contain private inholdings — patented mining claims or grandfathered private property — that are entirely outside federal jurisdiction.
Death Valley National Park is a useful example of park-specific complexity. The park spans California and Nevada, spans multiple land management categories, and contains private communities within its boundaries.
California and Nevada have different carry laws and different reciprocity agreements, meaning a carrier's status can shift across the park depending on their location and home state.
Yellowstone National Park presents the cross-state challenge at scale. Approximately 96% of Yellowstone sits in Wyoming, with the remaining area split between Montana and Idaho. All three states have different laws regarding permit requirements, open carry, and reciprocity.
Wyoming is a permitless carry state; Montana and Idaho are as well. But their reciprocity for non-resident permits differs, and the GFSZA analysis applies independently for each state section.
Before visiting any national park: call or email the specific park's law enforcement division and confirm current rules for the areas you plan to visit. The NPS website provides contact information for every park unit.
Carrying While Camping in a National Park
A common sub-question that most guides never fully answer: can you have a firearm at your campsite?
Yes. A national park campsite — whether a developed campground or a backcountry site — is park land, not a federal facility. The same state-law framework that governs trail carry governs campsite carry.
A carrier with a valid permit for the host state can keep a loaded firearm in their tent, on their person at a camp table, or accessible in a camp vehicle. There is no special camping prohibition under 36 CFR or 54 U.S.C. § 104906.
In a backcountry setting, the firearm you carry for wildlife defense (black bears and grizzly bears are legitimate concerns in multiple national parks) is lawful to keep accessible throughout your time in the backcountry.
Many experienced backcountry travelers in bear country choose a large-caliber revolver specifically for wildlife defense — the .44 Magnum and .454 Casull are the most commonly cited calibers for bear defense, though bear spray remains the primary and better-evidenced deterrent per NPS and wildlife biologist research.
The one camping-specific caveat: if you drive your vehicle into a campground and then walk to the camp store, pay station, or any other building that qualifies as a federal facility, the prohibition applies there just as it does at the visitor center.
Holster Considerations for National Park Carry
The carry context of a national park visit is meaningfully different from daily urban carry, and holster selection should reflect that.
For trail and backcountry carry, inside-the-waistband holsters that work well under a tucked shirt are less practical when wearing a pack with a hip belt. A pack's hip belt presses directly against the IWB carry position, making access slower and wear uncomfortable over long distances.
Outside-the-waistband strong-side carry at the three or four o'clock position remains accessible with most hip belt configurations if the belt rides above the holster. A chest holster is increasingly popular in backcountry and big-game hunting contexts — it positions the firearm on the chest where it is accessible regardless of pack configuration, and it keeps the firearm clear of brush and water crossings.
For day hiker carry where you'll be returning to a vehicle and a visitor center, IWB concealed carry works exactly as it does in any other environment. The primary operational consideration is the visitor center stop: plan to secure the firearm in the vehicle before entering.
For vehicle carry through the park, a firearm that stays in the vehicle while you enter federal facilities should be in a dedicated lockbox secured to the vehicle — not loose under a seat or in an unsecured bag in a parking lot. A vehicle break-in at a national park trailhead is not unheard of, and a stolen firearm recovered near park facilities creates a liability and legal headache that a $40 cable lockbox would have prevented.
Alien Gear's OWB holster lineup covers the strong-side carry positions that work best with pack carry, and the Cloak Tuck handles IWB day-use carry for carriers who want retention and comfort on extended day hikes.
Frequently Asked Questions
Can you carry a gun in a national park?
Yes. Under 54 U.S.C. § 104906, enacted in 2010, carrying a firearm in a national park is governed by the law of the state where the park is located. If your permit is valid in that state — or if the state allows permitless carry — you can carry on park land. Firearms are prohibited inside federal facilities such as visitor centers regardless of permit status.
Do you need a permit to carry a gun in a national park?
It depends on the state. Because national park carry rules follow state law, a permit is required if the host state requires one. If the park is in a permitless carry state and you qualify under that state's law, no permit is needed on park land — but see the Gun-Free School Zones Act caveat for permitless carriers near developed areas.
Can you open carry in a national park?
Yes, if the state where the park is located allows open carry. Open carry rules in national parks follow the same state-law framework as concealed carry. If the state prohibits open carry or requires a license for it, that rule applies in the park. Open carry is prohibited inside federal facilities in all cases.
Are guns allowed in national park visitor centers?
No. Visitor centers are federal facilities under 18 U.S.C. § 930, and firearms are prohibited inside regardless of your carry permit or the host state's laws. This applies to all NPS-staffed buildings, including ranger stations, backcountry permit offices, and park concession buildings in federally owned structures.
What changed in 2010 regarding guns in national parks?
Before February 2010, federal regulations required firearms in national parks to be unloaded, cased, and stored — effectively inaccessible. The Credit CARD Act of 2009 included an amendment, now at 54 U.S.C. § 104906, that replaced this blanket restriction with a framework deferring to state law. Carriers with valid state permits could, for the first time, carry loaded and accessible firearms on national park land.
Can you discharge a firearm in a national park?
No, except in genuine self-defense. Under 36 CFR 2.2, discharge of a firearm on national park land is prohibited. This is separate from carry authorization — a lawfully armed visitor still may not fire their weapon for target practice, pest control, or any purpose other than protecting human life.
Can you hunt in a national park?
No. Hunting is prohibited in national parks under 36 CFR 2.2, independent of carry rules. The 2010 change that authorized carry did not modify hunting prohibitions. National forests, BLM land, and some national recreation areas have separate and more permissive hunting rules.
Does my concealed carry permit work in national parks?
Your permit works in national parks if it is recognized by the state in which the park is located. This is a reciprocity question, not a national park-specific question. Check your permit's reciprocity status with the host state before visiting any park outside your home state.
Are national forests the same as national parks for gun rules?
No. National forests managed by the U.S. Forest Service follow state law for carry but have more permissive discharge rules — target shooting is permitted in designated areas, and hunting is allowed during state-regulated seasons. "National park" and "national forest" are legally distinct categories managed by different federal agencies under different regulatory frameworks.
Can you carry a gun while camping in a national park?
Yes. Campsites — both developed campgrounds and backcountry sites — are park land, not federal facilities. The standard state-law carry rules apply. A carrier with a valid permit for the host state can keep a firearm accessible in a tent, at a campsite, or in a camp vehicle. The federal facility prohibition applies only if you enter a building that qualifies as a federal facility within or adjacent to the campground.
What happens if you carry a gun illegally in a national park?
Violating 18 U.S.C. § 930 by carrying a firearm inside a federal facility carries up to one year imprisonment and fines for a first offense. Violations of state carry laws on park land carry whatever penalties that state prescribes. GFSZA violations (18 U.S.C. § 922(q)) are federal felonies carrying up to five years imprisonment.
What federal lands allow guns without a permit?
National forests, BLM land, and national wildlife refuges generally allow carry consistent with state law — meaning a permit is required if the host state requires one, and permitless carry is allowed if the host state allows it. There is no category of federal land that independently creates a permit exemption that does not exist under state law.
