The rules concerning firearms on National Park Service properties are set forth at the National Park Service website. Some key excerpts from this are as follows:
18 U.S. Code § 930 - Possession of firearms and dangerous weapons in Federal facilities
(a)Except as provided in subsection (d), whoever knowingly possesses

(c)A person who kills any person in the course of a violation of
subsection (a) or (b), or in the course of an attack on a Federal

in sections 1111, 1112, 1113, and 1117.
(d)Subsection (a) shall not apply to—
(1)the lawful performance of official duties by an officer, agent, or

thereof, who is authorized by law to engage in or supervise the
prevention, detection, investigation, or prosecution of any violation
of law;
(2)the possession of a firearm or other dangerous weapon by a Federal
official or a member of the Armed Forces if such possession is
authorized by law; or
(3)the lawful carrying of firearms or other
dangerous weapons in a Federal facility incident to hunting or other
lawful purposes.
(e)(1)Except as provided in paragraph (2), whoever knowingly possesses
or causes to be present a firearm or other dangerous weapon in a
Federal court facility, or attempts to do so, shall be fined under
this title, imprisoned not more than 2 years, or both.
(2)Paragraph (1) shall not apply to conduct which is described in
paragraph (1) or (2) of subsection (d).
(f)Nothing in this section limits the power of a court of the United
States to punish for contempt or to promulgate rules or orders
regulating, restricting, or prohibiting the possession of weapons
within any building housing such court or any of its proceedings, or
upon any grounds appurtenant to such building. (g)As used in this
section:
(1)The term “Federal facility” means a building or part thereof owned
or leased by the Federal Government, where Federal employees are
regularly present for the purpose of performing their official duties.
(2)The term “dangerous weapon” means a weapon, device, instrument,
material, or substance, animate or inanimate, that is used for, or is
readily capable of, causing death or serious bodily injury, except
that such term does not include a pocket knife with a blade of less
than 2½ inches in length.
(3)The term “Federal court facility” means the courtroom, judges’
chambers, witness rooms, jury deliberation rooms, attorney conference
rooms, prisoner holding cells, offices of the court clerks, the United
States attorney, and the United States marshal, probation and parole
offices, and adjoining corridors of any court of the United States.
(h)Notice of the provisions of subsections (a) and (b) shall be posted
conspicuously at each public entrance to each Federal facility, and
notice of subsection (e) shall be posted conspicuously at each public
entrance to each Federal court facility, and no person shall be
convicted of an offense under subsection (a) or (e) with respect to a
Federal facility if such notice is not so posted at such facility,
unless such person had actual notice of subsection (a) or (e), as the
case may be. . . .
54 U.S. Code § 104906. Protection of right of individuals to bear arms
(a)Findings.—Congress finds the following:
(1)The 2d amendment to the Constitution provides that “the right of
the people to keep and bear Arms, shall not be infringed”.
(2)Section 2.4(a)(1) of title 36, Code of Federal Regulations,
provides that “except as otherwise provided in this section and parts
7 (special regulations) and 13 (Alaska regulations), the following are
prohibited: (i) Possessing a weapon, trap or net (ii) Carrying a
weapon, trap or net (iii) Using a weapon, trap or net”.
(3)The regulations described in paragraph (2) prevent individuals
complying with Federal and State laws from exercising the 2d amendment
rights of the individuals while at System units.
(4)The existence of different laws relating to the transportation and
possession of firearms at different System units entrapped law-abiding
gun owners while at System units.
(5)Although the Bush administration issued new regulations relating to
the 2d amendment rights of law-abiding citizens in System units that
went into effect on January 9, 2009—
(A)on March 19, 2009, the United States District Court for the
District of Columbia granted a preliminary injunction with respect to
the implementation and enforcement of the new regulations; and
(B)the new regulations—
(i)are under review by the Obama administration; and
(ii)may be altered.
(6)Congress needs to weigh in on the new regulations to ensure that
unelected bureaucrats and judges cannot again override the 2d
amendment rights of law-abiding citizens on 83,600,000 acres of System
land.
(7)Federal laws should make it clear that the 2d amendment rights of
an individual at a System unit should not be infringed.
(b)Protection of Right of Individuals To Bear Arms in System
Units.—The Secretary shall not promulgate or enforce any regulation
that prohibits an individual from possessing a firearm, including an
assembled or functional firearm, in any System unit if—
(1)the individual is not otherwise prohibited by law from possessing
the firearm; and
(2)the possession of the firearm is in compliance with the law of the
State in which the System unit is located.
The references regulations in Title 36 of the Code of Federal Regulations state (emphasis added):

land ownership, on all lands and waters within a park area that are
under the legislative jurisdiction of the United States. . . .

(f) In addition to the authorities provided in paragraphs (d) and (e)
of this section, weapons (other than firearms), traps, and nets may be

residents who are authorized to engage in subsistence uses, including
the taking of wildlife under § 13.480, may use, possess, or carry
traps, nets and other weapons in accordance with applicable State and
Federal laws. . . .
§ 13.50 Closure and restriction procedures.
(a) Applicability and authority. The Superintendent will follow the
provisions of this section to close an area or restrict an activity,
or terminate or relax a closure or restriction, in NPS areas in
Alaska.
(b) Factors. In determining whether to close an area or restrict an
activity, or whether to terminate or relax a closure or restriction,
the Superintendent must ensure that the activity or area is managed in
a manner compatible with the purposes for which the park area was
established. The Superintendent's decision under this paragraph must
therefore be guided by factors such as public health and safety,
resource protection, protection of cultural or scientific values,
subsistence uses, conservation of endangered or threatened species,
and other management considerations.
(c) Rulemaking requirements. This paragraph applies only to a closure
or restriction, or the termination or relaxation of such, which is of
a nature, magnitude and duration that will result in a significant
alteration in the public use pattern of the area; adversely affect the
area's natural, aesthetic, scenic, or cultural values; or require a
long-term modification in the resource management objectives of the
area. Except in emergency situations, the closure or restriction, or
the termination or relaxation of such, must be published as a
rulemaking in the Federal Register.
(d) Written determination. Except in emergency situations, prior to
implementing or terminating a closure or restriction, the
superintendent shall prepare a written determination justifying the
action. That determination shall set forth the reasons the closure or
restriction authorized by paragraph (a) of this section has been
established. This determination will be posted on the NPS Web site at
www.nps.gov.
(e) Restrictions on taking fish or wildlife.
(1) Except in emergencies, the NPS will consult with the State agency
having responsibility over fishing, hunting, or trapping and provide
an opportunity for public comment, including one or more public
meetings near the affected NPS unit, prior to implementing a closure
or restriction on taking fish or wildlife.
(2) Emergency closures or restrictions may not exceed a period of 60
days and may not be extended without following the nonemergency
procedures of this section.
(f) Notice. A list of closures and restrictions will be compiled in
writing and updated annually. The list will be posted on the NPS Web
site at www.nps.gov and made available at park headquarters.
Additional means of notice reasonably likely to inform residents in
the affected vicinity will also be provided where available, such as:
(1) Publication in a newspaper of general circulation in the State or
in local newspapers;
(2) Use of electronic media, such as the internet and email lists;
(3) Radio broadcast; or
(4) Posting of signs in the local vicinity.
(g) Violating a closure or restriction is prohibited.
While the website notes that "Visitors should not consider firearms as protection from wildlife," this is advice, rather than a prohibition on using firearms in that fashion. It is a warning that firearms are a poor choice rather than a prohibition on using them for self-defense purposes. Also, if a use of firearms as self-defense against wildlife is determined to be unjustified, the park visitor might be charged with hunting without a permit.
The state gun control laws in the pertinent states are summarized as follows (by the High County News newspaper) (apologies for the small print):
