Navigating the legal landscape of firearm possession, particularly for non-residents, can be a complex undertaking when traveling. Colorado offers specific regulations regarding open carry, and understanding these nuances is crucial for visitors. This guide delves into the permissibility of open carry for individuals who are not permanent residents of the Centennial State, providing clarity for travelers planning a visit to popular destinations like Denver, Aspen, or the Rocky Mountains.
Understanding Open Carry in Colorado
Open carry, the practice of openly displaying a firearm, is subject to state-specific laws that can vary significantly. In Colorado, the general rule is that individuals who are legally allowed to possess a firearm may open carry it. This includes a significant portion of non-residents. However, this general permissibility comes with several important caveats and distinctions that travelers must be aware of.

Key Distinctions: Open Carry vs. Concealed Carry
It is vital to differentiate between open carry and concealed carry. While Colorado does not require a permit for open carry, concealed carry of a handgun typically requires a permit. For non-residents, understanding this distinction is paramount. If your intent is to open carry, the requirements are generally less stringent than if you intend to carry a concealed weapon.
Legal Age and Firearm Possession
The foundational requirement for anyone, resident or non-resident, to open carry in Colorado is that they must be legally eligible to possess a firearm. This typically means being at least 18 years of age. Federal law prohibits individuals under 18 from possessing handguns, and many states have similar age restrictions for long guns. Colorado aligns with federal law in this regard.
Prohibited Places and Situations
Even if you are legally permitted to open carry as a non-resident, there are specific locations and circumstances where doing so is prohibited. These restrictions are designed to ensure public safety in sensitive areas. Travelers should be particularly mindful of these prohibitions when planning their itinerary, whether visiting urban centers like Boulder or venturing into natural attractions.
Federal Buildings and Property
Possession of firearms, including open carry, is generally prohibited on federal property. This includes post offices, federal courthouses, and other federal government facilities. While these might not be common tourist stops, it’s a fundamental rule to remember.
Schools and Educational Institutions
Colorado law strictly prohibits carrying firearms on school grounds. This applies to K-12 schools and extends to institutions of higher education, such as University of Colorado Boulder. This prohibition is in effect during school hours and when school-related events are taking place.
Courthouses and Detention Facilities
Similar to federal buildings, carrying firearms in state courthouses and detention facilities is illegal. This is a standard measure to maintain security and order within the judicial system.
Private Property with Posted Restrictions
Private property owners have the right to prohibit firearms on their premises. If a business or private residence clearly posts signage indicating that firearms are not allowed, you are legally obligated to comply. This applies to hotels, restaurants, and other establishments. It is always advisable to respect private property rights.
Within Municipalities with Specific Ordinances

While Colorado state law generally permits open carry, some local municipalities may have adopted ordinances that further restrict or regulate it. It is incumbent upon travelers to research the specific laws of the cities and counties they plan to visit. For example, a city might have stricter rules about where firearms can be carried in public spaces.
While Under the Influence of Alcohol or Controlled Substances
Open carrying a firearm while under the influence of alcohol or any controlled substance is illegal in Colorado. This is a common-sense law aimed at preventing negligent or dangerous firearm handling.
Reciprocity and Recognition of Non-Resident Permits
For non-residents who possess a concealed carry permit from their home state, the question of recognition in Colorado is often a point of inquiry. Colorado recognizes concealed carry permits from states with substantially similar laws. However, as previously mentioned, open carry in Colorado does not require a permit, so the reciprocity of permits is more relevant to concealed carry. For travelers specifically interested in open carry, the focus remains on meeting the general eligibility requirements within Colorado.
Non-Resident Carrying a Handgun
For a non-resident who legally owns a handgun and is over 18, open carrying a handgun in Colorado is generally permissible, provided they are not in a prohibited location. There is no state permit required for this activity.
Non-Resident Carrying a Long Gun (Rifle or Shotgun)
The laws regarding long guns are typically more permissive than those for handguns. Open carry of a rifle or shotgun is generally allowed for non-residents over 18, again with the caveat of adhering to prohibited locations.
Important Considerations for Travelers
Beyond the explicit legal statutes, responsible firearm ownership and travel involve several practical considerations. Ensuring your firearm is unloaded and secured during transport, especially when flying or using public transportation, is paramount. Always comply with the specific regulations of transportation providers.
Traveling by Air
When traveling by air with a firearm, strict federal regulations governed by the Transportation Security Administration (TSA) apply. Firearms must be unloaded, placed in a locked hard-sided container, and declared to the airline at check-in. Ammunition must be stored separately and securely. It is crucial to check the specific airline’s policies in addition to TSA regulations.
Traveling by Vehicle
If you are driving to Colorado, ensure your firearm is legally possessed in your home state and that you are adhering to Colorado laws. Many states have reciprocity agreements, but it is always wise to verify. During your travel within Colorado, if you choose to open carry, be mindful of the prohibited locations mentioned previously.
Responsible Firearm Handling and Awareness
Regardless of residency status, responsible firearm ownership entails continuous training and a thorough understanding of applicable laws. When visiting Colorado, familiarize yourself with the state’s specific firearms statutes and any local ordinances. This proactive approach ensures a safe and lawful visit. Respecting the laws and customs of the places you visit is a hallmark of responsible travel.

Seeking Expert Advice
Given the complexities and potential for misunderstanding, it is always prudent to consult with a qualified legal professional specializing in firearms law in Colorado if you have specific concerns or unique circumstances. This is particularly true if your visit involves extensive travel within the state or if you are unsure about any aspect of the regulations. Staying informed and prepared is the best way to ensure a safe and lawful experience in Colorado.
