Possession of Firearms in National Park UnitsIn areas administered by the National Park Service, an individual can possess a firearm if that individual is not otherwise prohibited by law from possessing the firearm and if the possession of the firearm complies with the laws of the state where the park area is located. 54 U.S.C. 104906.
It is the responsibility of visitors to understand and comply with all applicable Federal, state and local firearms laws and regulations, including laws authorizing or prohibiting concealed carry, before entering a national park. Some parks are located in more than one state or locality which means that the applicable laws may change depending upon where you are located within a park area.
If a park is located in a jurisdiction where the applicable state and local laws grant reciprocity to non-resident firearm owners, then consistent with the applicable law, the park will equally recognize the reciprocity. For information on state and local laws, please contact the state and locality where the park is located.
