Firearms in National Parks: Rules and Regulations for Campers and Travelers

Summer travel brings many gun owners to national parks and campgrounds. These trips sometimes involve crossing state lines and entering public lands with complex firearm regulations. While federal law allows possession in national parks, state laws determine how and where you may carry. Failure to check these details often leads to legal violations.

This guide explains how firearms in national parks are regulated and how state and federal rules overlap. It also lists conditions that travelers must verify before attempting to carry a firearm in these areas.

Federal Law Allows Possession & State Law Controls Carry

In 2010, changes in federal law allowed gun owners to legally carry their firearms in national parks. However, this right depends entirely on state law that governs the park. In short, federal property does not automatically grant universal carry rights.

Key federal points include:

• National Park Service defers to state law for all carry regulations.
• Your permit remains valid within a park only if the state honors it.
• Firearms are always prohibited inside posted federal buildings.

State Laws Determine Carry Permissions

National parks often cross state lines, which means your carry permit might become invalid as soon as you enter a new state, even inside the same park system.

Travelers must review:

• Reciprocity agreements for every state entered.
• Differences in open and concealed carry rules across state lines.
• State requirements for transporting loads or empty vehicles within park areas.

Resources like the USCCA Reciprocity Map and HandgunLaw.us help verify state-level requirements before departure.

Federal Buildings Remain Off-Limits

Carrying inside federal buildings remains prohibited under 18 U.S.C. § 930. Violating this rule may lead to federal charges.

Restricted federal buildings include:

• Visitor centers
• Ranger stations
• Administrative offices.
• Maintenance buildings
• Any posted government-operated indoor facilities

These buildings usually display clear signage prohibiting firearm entry.

Campgrounds Follow Separate Property Rules

Campgrounds on public or private land follow different firearm policies. Ownership determines which rules apply.

Important distinctions include:

• Private campgrounds may ban firearms completely.
• National Forest and BLM campgrounds often follow state firearm laws.
• Federal concessionaire campgrounds may impose additional restrictions.

Travelers must confirm campground policies directly with management or review written policies before arrival.

Common Legal Violations on Public Lands

Travelers often break firearm laws by misunderstanding how state, federal, and property rules interact.

Frequent violations include:

• Carrying into posted federal buildings inside parks.
• Crossing into states where your permit lacks reciprocity.
• Failing to secure unloaded firearms during state line crossings.
• Entering private campgrounds without confirming firearm policies.

Each violation may result in criminal charges or firearm confiscation.

Transporting Firearms Under Federal Protection

The Firearm Owners Protection Act (FOPA) allows the transportation of firearms across states where possession may otherwise be illegal, but only under strict conditions.

To comply with FOPA:

• Firearms must remain unloaded.
• Firearms must be locked in a separate container from the passenger area.
• Ammunition should be stored apart from the firearm.
• You must be legal to possess the firearm at both trip origin and destination.

FOPA protections face challenges in some states. Study ATF’s FOPA guidance before starting multi-state trips.

Planning for Firearms in National Parks Before Your Trip

Traveling armed through national parks requires thorough preparation. Verify your permit status in every state. Confirm whether federal or private campgrounds allow firearm possession. Review which park buildings prohibit firearms under federal law. Failure to verify these details can lead to criminal charges, permit suspension, or firearm seizure.

If you’ve traveled with firearms across state lines or through national parks, share which research steps, legal checks, or campground contacts helped keep your trip compliant. Your preparation experience may help others plan safe, legal trips while carrying firearms in national parks.
