Since February 22nd, those that are legally able, have been allowed to carry a concealed firearm in National Parks. However, the law is not all encompassing.
The NRA-ILA has recently put together an outstanding resource list of the links to the NPS Firearm Regulations for each individual National Park.
While it may be legal now to carry in National Parks, federal law continues to prohibit the possession of firearms in designated “federal facilities” within national parks, for example, visitor centers, offices, or maintenance buildings.
These places are posted with “firearms prohibited” signs at public entrances. The new law also does not change prohibitions on the use of firearms in national parks (which is prohibited) and does not change hunting regulations. If anything, this list will save you some time when selecting your next vacation spot.
It’s also important to note that it’s still illegal for bears to possess firearms!
