National Parks and National Wildlife Refuges (NWR) Carry
National Park Carry will go into effect February 22, 2010. That means if you have a
permit/license that is legal in the state the National Park is located in you can carry in that
National Park. Until that time carry in National Parks is illegal.

refuge in accordance with the laws of the state in which the wildlife refuge, or that

National Forests
Some states have laws concerning carrying in National Forest. You must know the law.
In most states if it is legal for you to carry a firearm concealed in the state the National Forest is
in you can carry your firearm concealed in a National Forest in that state. If it is legal to carry a
firearm openly on your hip in the state the National Forest is in you can legally carry it that way
in the National Forest in that state. Some states have have laws against carrying in National
Forests in their state. Look at each states page to see if it is legal to carry in National Forests in
that state.
Do be advised that any Ranger Station or Visitors Center in any National Forest is considered
a Federal Building. It is illegal to carry any firearm into such a building either concealed or
openly even with a CCW from the state the National Forest Ranger Station or Visitors Center is
in.
And this appears to be actual Federal code

§ 2.4 Weapons, traps and nets.
(h) Notwithstanding any other provision in this Chapter, a person may possess, carry, and transport concealed, loaded, and operable firearms within a national park area in accordance with the laws of the state in which the national park area, or that portion thereof, is located, except as otherwise prohibited by applicable Federal law.
And apparently you have to disarm to walk into the bathrooms or the ranger stations, because they are government owned buildings. "Here hunny hold this...I have to pee" Or "here hunny hold this, take a seat I might be in there a few minutes" LoL
