Open carry in Colorado
Last verified against primary sources: · Updated
Yes — open carry is generally legal for adults in Colorado who may lawfully possess a firearm. No statewide statute creates a general open-carry offense; Colorado's core carrying crime, C.R.S. § 18-12-105, reaches only firearms carried concealed. This is an absence-of-prohibition finding — the law does not affirmatively grant an open-carry right, it simply does not criminalize it statewide.
That baseline has real limits. Since 2021, local governments may ban open carry in posted buildings and areas; Denver bans open carry outright; and statewide "sensitive place" laws — government buildings, schools, child care centers, colleges, and polling places — prohibit carrying a firearm whether openly or concealed.
The statewide baseline: no general open-carry ban
Colorado's central weapons offense is C.R.S. § 18-12-105, titled "Unlawfully carrying a concealed weapon — unlawful possession of weapons." By its terms it reaches firearms carried concealed, not firearms carried openly and visibly. No statute of general application banning open carry appears anywhere in the Colorado Revised Statutes. Instead, Colorado regulates concealed carry (through the permit system) and carrying in specific enumerated locations.
Because the offense turns on concealment, the line between legal open carry and illegal unlicensed concealed carry matters. The statute itself does not define "concealed." Colorado courts — not the statute — supply the test: "concealed" means placed out of sight so as not to be discernible or apparent by ordinary observation (People ex rel. O.R., Colo. App. 2008). A holstered handgun worn openly on the hip is not concealed; the same handgun tucked under a jacket is.
This page describes where open carry is allowed and where it is prohibited. It is a reference, not legal advice. For a live situation, consult a Colorado attorney. See also our full list of places you cannot carry a gun in Colorado.
Local governments can ban open carry (SB21-256)
Colorado used to preempt most local firearm rules. SB21-256 (2021) changed that, declaring firearm regulation "a matter of state and local concern" and letting local governments regulate more strictly than before.
Unless otherwise expressly prohibited pursuant to state law, a local government may ... enact an ordinance, regulation, or other law governing or prohibiting the sale, purchase, transfer, or possession of a firearm, ammunition, or firearm component or accessory that a person may lawfully sell, purchase, transfer, or possess under state or federal law.
The companion permit statute confirms that a local government that restricts carry in a building or area must post signs — and that a single sign can carry both the open-carry and concealed-carry restriction:
If a local government or governing board prohibits carrying a concealed handgun in a building or specific area, the local government or governing board shall post signs at the public entrances to the building or specific area informing persons that carrying a concealed handgun is prohibited in the building or specific area. The notice required by this section may be included on a sign describing open carry restrictions posted in accordance with section 29-11.7-104.
The standalone text of § 29-11.7-104 — the section that spells out the local open-carry-signage authority the cross-reference above points to — is what a city relies on to ban open carry in, for example, a recreation center or a park building. Denver has used this framework to prohibit open carry citywide. If you see posted signage, treat the restriction as binding.
Sensitive places apply to open carry too
Several statewide "sensitive place" bans do not care whether you carry openly or concealed — they prohibit the firearm outright. These come mostly from SB24-131 (2024) and apply regardless of any permit.
Government buildings, courthouses, and the legislature (§ 18-12-105.3)
A person shall not knowingly carry a firearm, whether loaded or not loaded, in any of the following locations, including their adjacent parking areas: (a) On the property of or within any building in which: (I) the chambers, galleries, or offices of the general assembly, or either house thereof, are located; (II) a legislative hearing or meeting of the general assembly is being conducted; or (III) the official office of any member, officer, or employee of the general assembly is located; (b) unless permitted by a local government, as described in subsection (4)(b) of this section, on the property or within any building in which: (I) the chambers or galleries of a local government’s governing body are located; (II) a meeting of a local government’s governing body is being conducted; or (III) the official office of any elected member of a local government’s governing body or of the chief executive officer of a local government is located; or (c) a courthouse or any other building or portion of a building used for court proceedings.
Because the ban covers "a firearm, whether loaded or not loaded," it applies to open carry the same as concealed carry. It is a class 1 misdemeanor. Narrow exceptions exist for peace officers, on-duty military, security personnel, and court/law-enforcement personnel; a concealed-carry permittee may keep a concealed handgun in the adjacent parking area, but that carve-out is for concealed carry, not open carry.
Schools, colleges, and licensed child care centers (§ 18-12-105.5)
A person shall not knowingly carry a firearm, either openly or concealed, in or on the real estate and all improvements erected thereon of any licensed child care center; public or private elementary, middle, junior high, high, or vocational school; or any public or private college, university, or seminary; except for the purpose of presenting an authorized public demonstration or exhibition pursuant to instruction in conjunction with an organized school or class, for the purpose of carrying out the necessary duties and functions of an employee of an educational institution that require the use of a firearm, or for the purpose of participation in an authorized extracurricular activity or on an athletic team.
This provision names open carry expressly ("either openly or concealed") and adds licensed child care centers alongside schools and colleges. A violation is a class 1 misdemeanor. SB24-131 also narrowed the concealed-carry-permit exception on campuses — see the prohibited-places page for how the permit exemption now works.
Polling places and drop boxes (§ 1-13-724)
The Vote Without Fear Act originally banned only open carry near voting sites. SB24-131 struck the word "openly," extending the ban to concealed carry as well — so both are now prohibited:
It is unlawful for any person to carry a firearm, as defined in section 18-1-901 (3)(h), within any polling location, or within one hundred feet of a drop box or any building in which a polling location is located, as publicly posted by the designated election official, on the day of any election or during the time when voting is permitted for any election.
There is a private-property exception for owning and carrying on your own property inside the 100-foot buffer, and for uniformed contract security guards and certain security personnel.
Federal locations
Federal law bars firearms in federal facilities regardless of Colorado law:
Except as provided in subsection (d), whoever knowingly possesses or causes to be present a firearm or other dangerous weapon in a Federal facility (other than a Federal court facility), or attempts to do so, shall be fined under this title or imprisoned not more than 1 year, or both.
A "Federal facility" is a building or part of one owned or leased by the federal government where federal employees regularly work. Federal courthouses are separately and more strictly regulated under § 930(e). U.S. post offices are covered by their own rule:
Weapons and explosives. Notwithstanding the provisions of any other law, rule or regulation, no person while on postal property may carry firearms, other dangerous or deadly weapons, or explosives, either openly or concealed, or store the same on postal property, except for official purposes.
Parks and public lands
Colorado state parks — carry follows Title 18
Colorado state parks do not add a carry restriction beyond general state law. Colorado Parks & Wildlife regulation ties lawful carry to Title 18 compliance and separately affirms concealed carry by a valid permit holder:
It shall be unlawful: ... To possess, carry, or discharge explosives, firearms and/or other weapons on Parks and Outdoor Recreation Lands or Waters in any manner that violates Title 18, C.R.S., or any other applicable law. The lawful carry of concealed handguns by persons in possession of a valid concealed handgun permit, together with valid photo identification, is permitted. The possession or discharge of fireworks is prohibited. The lawful possession and/or discharge of firearms on designated shooting ranges is permitted.
The park-specific restrictions are on discharge, not carry: shooting is unlawful within 100 yards of any designated campground, picnic area, boat ramp, swimming or water-skiing beach, or nature trail and study area, except as otherwise posted, and target shooting is limited to designated ranges.
National parks and national forests
National parks in Colorado (Rocky Mountain, Great Sand Dunes, Mesa Verde, Black Canyon, Colorado National Monument) defer to state law for carry:
(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 National Park System unit is located.
So if open carry is lawful under Colorado law, it is generally lawful in a national park here — but federal buildings inside park boundaries (visitor centers, ranger stations) remain off-limits under 18 U.S.C. § 930, and discharge is separately restricted. National forests in Colorado also defer to Colorado state law for carry, with the same federal-building carve-out.
Common questions
Is open carry legal in Colorado?
Generally yes. No Colorado statute creates a general open-carry offense — the core carrying crime, C.R.S. § 18-12-105, reaches only concealed carry. Open carry is still barred in statewide "sensitive places" (government buildings, schools, child care, colleges, polling places), on federal property, anywhere a local government has posted a ban, and in cities like Denver that prohibit it.
Do you need a permit to open carry in Colorado?
No. Colorado's concealed-handgun permit is required to carry concealed; it is not required to carry openly where open carry is lawful. A holstered handgun worn visibly is not "concealed" under the case-law test (out of sight so as not to be discernible by ordinary observation).
Can a city or county ban open carry in Colorado?
Yes. Since SB21-256 (2021), local governments may regulate firearms more strictly than before, including prohibiting open carry in specified buildings and areas with posted signage (C.R.S. §§ 29-11.7-103, -104). Denver bans open carry citywide.
Can you open carry in a Colorado state park?
Generally yes. Colorado Parks & Wildlife regulation ties lawful carry to Title 18 compliance rather than adding a park-specific carry ban (2 CCR 405-1, Reg. #106.A.1). Park rules restrict discharge — no shooting within 100 yards of developed areas, target shooting only on designated ranges — not lawful carry.
Can you open carry in a national park in Colorado?
Generally yes, if it is lawful under Colorado state law. 36 C.F.R. § 2.4 defers to the law of the state where the park unit sits. But federal buildings inside the park (visitor centers, ranger stations) are off-limits under 18 U.S.C. § 930, and discharging a firearm in a park is separately restricted.
Is open carry allowed at the Colorado Capitol?
No. Carrying a firearm — openly or concealed, loaded or unloaded — is prohibited in buildings housing the chambers, galleries, or offices of the general assembly, or where a legislative hearing is held, including adjacent parking areas (C.R.S. § 18-12-105.3(1)(a)). A violation is a class 1 misdemeanor.
