Can You Bring a Gun to a National Park? State Law and Buildings

You can bring a gun to a national park if you are legally allowed to possess that firearm under the laws of the state where the park is located. A 2010 federal law ended the old blanket ban and handed the question to state law: if the state says you can carry, the National Park Service cannot stop you. The catch is that carrying is not the same as using, and certain buildings inside the park remain firearm-free no matter what state you are in.

State Law Is the Test

The controlling statute is 54 U.S.C. § 104906. It bars the Secretary of the Interior from enforcing any regulation that prohibits firearm possession inside a National Park System unit, as long as you are not otherwise prohibited by law from having the firearm and your possession complies with the law of the state the park sits in.¹ The law took effect February 22, 2010, and the Park Service confirms that visitors who comply with federal, state, and local firearms laws may possess firearms in park areas.²

There is no NPS permit for carrying, no park-specific registration, and no ranger check-in. The whole question reduces to a simpler one: could you legally carry this firearm, in this way, on the sidewalk just outside the park? If yes, you can carry it on the trail.

What “State Law Applies” Actually Means for Your Trip

Because the reference point is state law, the practical rules shift park by park. Roughly 29 states have some form of permitless carry as of early 2026; in those states, no permit is generally needed inside the park either. In states that require a concealed carry permit, that requirement follows you through the entrance station.²

A few things trip visitors up:

Parks that straddle state lines put you under different firearm rules on different sides of the border. Yellowstone alone spans three states.
A concealed carry permit from your home state may not be recognized where the park is located. Carrying on an unrecognized permit is the same as carrying without one.
Some states allow open carry without a permit but require one for concealed carry, or the reverse. How you carry matters as much as whether you carry.
Several states impose a duty to inform any law enforcement officer during a stop that you are armed. If a ranger pulls you over, that obligation applies.

The Park Service puts the research burden on visitors, and there is no grace period for getting it wrong. If you are driving cross-country and stopping in several parks, you need to know the carry laws for every state along the route.²

Buildings Where Guns Are Never Allowed

Even in the most permissive state, you cannot bring a firearm into a federal facility inside a national park. Under 18 U.S.C. § 930, it is a federal crime to knowingly possess a firearm in any building or portion of a building owned or leased by the federal government where federal employees regularly work. These buildings must be posted with notice at every public entrance.³

In a typical park, that covers visitor centers, ranger stations, park headquarters, fee collection buildings, and maintenance facilities.² Before you enter one, secure the firearm elsewhere. The Park Service says to store it in accordance with applicable federal, state, and local law, which in practice usually means locked in your vehicle, out of sight and inaccessible.⁴

Lodges and restaurants run by private concessioners are a common gray area. The statute defines a federal facility by federal ownership or lease plus regular federal employee presence, so a concessioner-staffed lodge often will not qualify. But individual parks can post those buildings as restricted, and concessioners may set their own policies. Look for the posted signs before you walk in armed.

Carrying Is Not Firing

The right to carry a firearm in a park does not include the right to shoot it. Under 36 C.F.R. § 2.4, using a weapon in a park area is prohibited except in narrow circumstances.⁵ No warning shots at wildlife. No plinking at targets on a hillside. No discharge for any reason not covered by a specific exception.

The exceptions are limited:

Hunting or fishing where federal law specifically authorizes it in that park unit, subject to federal and state regulations.
Target shooting at designated ranges in the handful of parks that have them, during designated times.
Self-defense is not pre-authorized by regulation, but that does not make it automatically illegal. Any discharge will be investigated, and whether the shooting was justified gets evaluated under the self-defense law of the state where it happened. The standard is the same one you would face outside the park.

Hunting: Parks vs. Preserves

The no-hunting reputation of the national parks is accurate for the marquee ones like Yellowstone and the Grand Canyon. But the National Park System also includes national preserves, national recreation areas, and certain national seashores and lakeshores, some of which allow hunting where the federal statute creating the unit specifically mandates or authorizes it.⁶

Where hunting is allowed, both federal NPS regulations and the game laws of the surrounding state apply. State seasons, bag limits, and licensing all count. Superintendents can also add conditions, such as how you transport game through the park.⁶ Check the specific park unit’s rules and the state wildlife agency’s rules before you go.

Driving Through With a Gun You Can’t Otherwise Carry There

If your route takes you through a park in a state that would not otherwise let you carry, the federal safe-passage law may protect you. Under 18 U.S.C. § 926A, a person legally allowed to possess the firearm at both origin and destination may transport it through any state in between, provided the firearm is unloaded and neither the gun nor its ammunition is readily accessible from the passenger compartment. In vehicles without a separate trunk, both must be in a locked container other than the glove compartment or center console.⁷

Two limits to keep in mind. Section 926A operates as a defense, not a permission slip, so you can still be detained and forced to assert it. And it protects transport, not extended stops. Camping overnight in a park under a safe-passage theory is a stretch most lawyers would not recommend.

What Violations Cost

The penalty depends on which law you broke. Bringing a firearm into a posted federal building inside a park is a federal offense under 18 U.S.C. § 930, carrying up to one year in prison, a fine, or both. If prosecutors can show intent to use the weapon in a crime, the maximum jumps to five years.³

Violating NPS-specific rules, such as discharging a firearm where prohibited, falls under 18 U.S.C. § 1865, with a maximum of six months in prison, a fine, or both, plus court costs.⁸ On top of any federal exposure, you can be charged under state law for any state offense committed inside the park, and a single incident can produce federal and state charges at the same time.
