Introduction

You’re packing your kit for a week-long trek through the backcountry of the Rockies. You’ve got your water purification collection ready, your shelter is checked, and your emergency kit is staged. For many outdoor enthusiasts in the West, the question of personal protection naturally follows. Whether it’s for defense against aggressive wildlife or general peace of mind in remote areas, understanding how to legally carry a firearm is a critical part of your trip planning.

In Colorado, the rules have shifted significantly in recent years. What was once a relatively straightforward state for firearm owners has become a patchwork of local ordinances and state-level changes. At BattlBox, we believe that true preparedness starts with accurate information. This guide covers the essential details of the Colorado open carry law, where you can legally carry, the impact of local bans, and how to stay compliant while enjoying the outdoors. Our goal is to help you navigate these regulations so you can focus on the adventure ahead. If you want to keep building that kit between trips, subscribe to BattlBox.

Quick Answer: In Colorado, open carry is generally legal for adults 21 and older who can legally possess a firearm, but local governments now have the power to ban it. Major areas like Denver and Boulder have strict prohibitions, and certain locations like schools and government buildings remain off-limits statewide.

The Foundation of Colorado Open Carry Law

To understand the current legal landscape, we first need to define what open carry means in a legal context. Open carry refers to the act of carrying a firearm in a manner that is visible to the ordinary observer. This is distinct from concealed carry, which involves keeping the weapon hidden from view, usually requiring a state-issued permit (CCW).

In Colorado, there is no state statute that explicitly grants the right to open carry; rather, it has historically been legal because there was no state law prohibiting it. For decades, Colorado operated under a principle called "state preemption." This meant that firearm laws were uniform across the entire state, preventing a city from making a law stricter than the state's law.

However, the legal environment changed drastically in 2021. The passage of Senate Bill 21-256 effectively ended state preemption. This allows cities, counties, and local municipalities to enact their own firearm regulations that are more restrictive than state law. As a result, the legality of open carry can change the moment you cross a city limit or county line.

Understanding the "Patchwork" of Local Laws

Because of the loss of preemption, Colorado is now often described as a "patchwork" state for gun owners. This is the most critical piece of information for anyone traveling through the state. You might be perfectly legal open carrying in a rural county, but as soon as you enter a specific city or town, you could be in violation of a local ordinance.

The Denver Exception

Denver has long been an outlier in Colorado. Even before the 2021 changes, Denver maintained a ban on open carry that was upheld by the courts. In the City and County of Denver, open carry is strictly prohibited. If you are traveling through Denver, your firearm must be concealed (if you have a permit) or stored according to local transport laws.

Other Local Bans

Since the preemption law changed, several other localities have moved to ban open carry in public places. These include:

• Boulder: The city and parts of the county have implemented strict prohibitions.
• Fort Collins: Recent discussions and ordinances have targeted open carry in city-owned buildings and parks.
• Edgewater and Superior: These smaller municipalities have also moved to restrict open carry.

Before you head out on a trip, it is your responsibility to check the local ordinances of every jurisdiction you plan to visit or pass through. Many town websites list their municipal codes online.

Where Open Carry is Prohibited Statewide

Regardless of local ordinances, there are specific locations across Colorado where open carry is prohibited by state or federal law. Carrying a firearm in these areas can lead to serious legal consequences, including felony charges.

Schools and Universities

Carrying a firearm on the grounds of any public or private elementary, middle, or high school is illegal in Colorado. There are limited exceptions for those who have a concealed carry permit and remain in their vehicle, but open carry is strictly forbidden. Most college campuses also have specific policies or are subject to local bans.

Government and Legislative Buildings

Following recent legislation, firearms are prohibited in the Colorado State Capitol and many other government buildings. This includes courthouses, polling places during elections, and any building where the local government has posted a "no firearms" sign.

Federal Lands and Buildings

Colorado is home to vast amounts of federal land, including National Parks and National Forests. While federal law generally aligns with state law regarding possession, federal buildings (like visitor centers, ranger stations, and post offices) are strictly gun-free zones. For backcountry trips, your camping collection is a smart place to start.

Key Takeaway: Colorado’s open carry legality is highly dependent on your specific GPS coordinates; always verify local municipal codes before displaying a firearm.

Requirements for Open Carrying in Colorado

Even in areas where open carry is permitted, there are basic legal requirements you must meet. Violating these can result in the loss of your right to possess a firearm or criminal charges.

Age Requirements

To open carry a handgun in Colorado, you must be at least 21 years old. While federal law allows for the possession of long guns by those 18 and older, Colorado's specific regulations regarding the public display of handguns generally fall under the 21+ age bracket for most practical purposes.

Legal Possession

You must be a person who is legally allowed to possess a firearm under both state and federal law. You are prohibited from carrying if:

1. You are a convicted felon.
2. You are under a restraining order that prohibits firearm possession.
3. You have been convicted of certain domestic violence misdemeanors.
4. You are an unlawful user of controlled substances (Note: While marijuana is legal in Colorado, it remains illegal federally, which can create complications regarding firearm possession).

The Manner of Carry

Open carry means the firearm must be visible. If a jacket or shirt partially covers the holster, it could be legally interpreted as "concealed." In Colorado, carrying a concealed firearm without a valid Concealed Handgun Permit (CHP) is a crime. If you intend to open carry, ensure the firearm is clearly visible to avoid any ambiguity.

Open Carry in Vehicles

Transporting a firearm in your vehicle is a common necessity for campers and hikers. Colorado law allows for the possession of a handgun in a vehicle for lawful protection.

• Handguns: You may have a handgun inside your vehicle, either concealed or open, as long as it is for lawful protection of yourself or your property while traveling.
• Long Guns (Rifles and Shotguns): Colorado law is stricter here. It is illegal to have a "loaded" firearm in a vehicle if it is a rifle or shotgun. Under Colorado wildlife laws, a long gun is considered loaded if there is a round in the chamber. This is primarily a poaching prevention measure.

Note: While state law allows handguns in vehicles, some cities (like Denver) have specific storage requirements if the firearm is left unattended. Always lock your vehicle and consider a dedicated vehicle safe.

Open Carry in the Backcountry: Practical Advice

For many of our readers, the primary reason to open carry is for protection while hiking, camping, or hunting. In the deep woods, the legal landscape is generally more permissive, but practical concerns become more prominent.

BLM and National Forest Lands

Generally, open carry is allowed on Bureau of Land Management (BLM) and National Forest lands in Colorado, provided you are not in a prohibited area (like a federal building). These are the prime areas for dispersed camping and backcountry exploration, and it helps to know how to build a survival shelter.

Wildlife Considerations

If you are carrying for protection against bears or mountain lions, remember that a firearm is a last resort. We recommend also carrying bear spray, as it has been proven highly effective at deterring bears without the need for lethal force. If you do use a firearm against wildlife, you are often required to report the incident to Colorado Parks and Wildlife (CPW) immediately.

Interaction with Other Trail Users

Open carry can be a polarizing topic. When you are on a popular trail, you will encounter people with varying levels of comfort around firearms.

1. Retention is Key: Use a high-quality holster with active retention. If you want a compact add-on for the rest of your carry system, the Flextail Tiny Tool - Ultimate 26-in-1 EDC Tool is worth a look.
2. Professionalism: A calm, respectful demeanor goes a long way. If you are open carrying, you are effectively an ambassador for the 2A community.
3. Local Context: If you are hiking near a city like Boulder, be aware that the trail might pass through city-owned open space where carry rules are different than in the adjacent National Forest.

Interaction with Law Enforcement

If you are open carrying and encounter law enforcement, it is important to remain calm and follow a few basic steps to ensure the interaction goes smoothly.

Step 1: Keep your hands visible. / Do not reach for your firearm or make sudden movements toward your waistband. Step 2: Disclose early. / If the officer hasn't noticed the firearm, it is often helpful to calmly state, "Officer, I want to inform you that I am openly carrying a firearm on my right hip." Step 3: Follow instructions. / If an officer asks you to provide identification or temporarily secures your firearm for their safety, comply and address any grievances later through proper channels.

In Colorado, you are not legally required to disclose that you are carrying a firearm unless an officer asks, but doing so proactively often de-escalates the natural tension of the situation.

Myth vs. Fact: Colorado Firearm Laws

Myth: A concealed carry permit allows me to open carry anywhere in the state. Fact: A CCW permit only applies to concealed carry. It does not override local bans on open carry. In fact, in places like Denver, you must carry concealed (with a permit) because open carry is banned.

Myth: I can drink alcohol while open carrying as long as I’m not drunk. Fact: Colorado law prohibits the possession of a firearm while under the influence of alcohol or controlled substances. The legal threshold is often subjective, so the best practice is to never mix firearms and alcohol.

Choosing Gear for Open Carry

If you decide to open carry in the Colorado outdoors, your choice of gear is vital. This isn't just about the firearm; it’s about the system you use to carry it. Our team at BattlBox often discusses the importance of gear reliability, and that is especially true for EDC collection options.

Holster Selection

For open carry, especially in the backcountry, you should look for:

• Level 2 or Level 3 Retention: These holsters have a physical mechanism (like a thumb break or a button) that you must engage to draw the gun. This prevents the gun from falling out during physical activity.
• Durability: Kydex or heavy-duty leather is preferred over cheap nylon. Your holster needs to withstand rain, mud, and brush.
• Comfort: If you are wearing a heavy pack with a hip belt, a standard OWB (Outside the Waistband) holster might interfere. You may need a "drop-leg" rig or a chest holster to clear your pack's straps.

Support Gear

A firearm is just one tool in your kit. To be truly prepared, you should also carry:

• Medical Gear: If you carry a tool that can make holes, you should carry a tool to plug them. The Adventure Medical Ultralight/Watertight .9 Medical Kit is a solid place to start.
• Communication: In remote areas, a satellite messenger is a lifeline if an emergency occurs. If you want a broader checklist, read What to Have on Hand for Emergency Preparedness.
• Proper Lighting: A powerful EDC flashlight is essential for identifying threats or navigating after dark. The Powertac E3R Nova - 820 Lumen Rechargeable Flashlight fits that role well.

Bottom line: Open carry in Colorado requires a high-quality retention holster and a deep understanding of the local laws in the specific area where you are traveling.

Firearm Safety and Public Perception

While the legal right to open carry exists in much of the state, the social responsibility that comes with it is significant. Firearm safety is non-negotiable.

1. Treat every firearm as if it is loaded.
2. Never point the muzzle at anything you aren't willing to destroy.
3. Keep your finger off the trigger until you are ready to fire.
4. Be sure of your target and what is beyond it.

In an outdoor setting, "what is beyond it" is particularly important. Bullets can travel long distances in open terrain. If you are target shooting (where legal) or defending against an animal, you must be aware of other hikers or campers who might be in the area.

The Role of Training

No piece of gear can replace training. If you plan to carry a firearm for protection, you should seek professional instruction. This includes:

• Marksmanship: Being able to hit your target under stress.
• Drawing from the Holster: Practicing your draw stroke with your specific retention holster until it is muscle memory.
• De-escalation: Learning how to avoid a conflict before it requires the use of a firearm.
• Legal Training: Understanding the specific statutes regarding the "Use of Deadly Physical Force" in Colorado (Title 18, Article 1, Part 7).

We always encourage our community to spend as much time training as they do researching gear. If you want a broader equipment breakdown, start with Best Multitools for Everday Carry (EDC).

How Localities Post Their Bans

If a city or county has banned open carry, they are often required to provide notice. This usually takes the form of signage at the entrances to parks or public buildings. However, the law does not always require a sign at every single street crossing into a city.

It is your responsibility to know when you have entered a municipality like Boulder or Denver. Using a mapping app to track city boundaries can be a helpful way to stay compliant while on the move.

Preparing for the Unexpected

Firearm carry is just one facet of a broader self-reliance mindset. Whether you’re dealing with a mechanical failure on your vehicle, a sudden shift in weather, or a medical emergency, being prepared means having the right tools and the knowledge to use them.

Our mission at BattlBox is to provide you with those tools. Every month, we curate gear that helps you build a more robust emergency kit, a more capable EDC setup, and a more comfortable camp.
