Bottom line is, always check the laws where you plan to go because it's confusing. We were allowed to bring rifles into Grand Canyon years ago. But we let the Ranger at the gate know that we were on a trip to hunt in Pagosa Springs CO. They asked if they were in cases & unloaded, they were.

Firearms in National Parks
The law governing possession of firearms inside a national park changed on February 22, 2010.
Visitors may possess firearms within a national park unit provided that they comply with federal, state and local laws.
The role of the responsible gun owner is to know and obey the federal, state, and local laws appropriate to the park they are visiting.
Gateway National Recreation Area includes areas in two states. Sandy Hook Unit is in New Jersey and follows the laws of that state. Jamaica Bay and Staten Island Units are in New York state and follow its laws. It is up to the individual to know the laws of the state they are in and where they are in the park.
Please remember that federal law prohibits firearms in certain park facilities and buildings. These places are marked with signs at public entrances.
