As of February 22, 2010, a new federal law allows people who can legally possess firearms under applicable federal, state, and local laws to legally possess firearms in this park.
“For nearly 100 years, the mission of the National Park Service has been to protect and preserve the parks and to help all visitors enjoy them,” National Park Service Director Jon Jarvis said. “We will administer this law as we do all others – fairly and consistently.”
It is the responsibility of visitors to understand and comply with all applicable state, local, and federal firearms laws before entering this park.

Federal law also prohibits firearms in certain facilities in this park; those places are marked with signs at all public entrances.
