Colorado generally permits open carry of firearms by adults without a license, though local jurisdictions may impose restrictions in specific areas after the 2021 preemption repeal.
State law does not require a permit to openly carry a firearm in most public places for those legally allowed to possess one. However, the city of Denver has long prohibited open carry within city limits, and after the 2021 repeal of CRS 29-11.7-103 additional local jurisdictions enacted open carry restrictions in parks, near schools, and at public events. Open carry is prohibited on school grounds, in courthouses, and in establishments licensed to serve alcohol where signs forbid weapons. Travelers should always verify local rules.
Violations vary by jurisdiction; in restricted areas, charges typically include disorderly conduct or unlawful carry with fines from $100 to $1,000.
