Colorado Bear Season 2026-27
In the fall, bears enter a period of compulsive overeating (hyperphagia). They start feeding for 22 hours a day to gain the 20,000 calories a day they need to survive hibernation.
Colorado Parks and WildlifeRifle (over-the-counter and/or limited): October 14, 2026 to November 22, 2026. People report black bears in Colorado most in July, and 22 percent of all reports fall in September, October and November. Everything below is Colorado Parks and Wildlife’s own words and dates, read on September 19, 2026, beside the record of what people reported.
When black bears are most active in Colorado
Colorado Parks and Wildlife estimates 17,000 to 20,000 bears in Colorado, and says the largest populations of black bears live in areas where there is Gambel's oak and aspen, near open areas of chokecherry and serviceberry bushes. Grizzly bears were extirpated in Colorado in the mid 1950s.
The bars count research grade American black bear observations people uploaded to iNaturalist for Colorado, by calendar month, across every year the platform holds. The busiest month in the record is July, and reports drop below 40 percent of that peak by October. The drop into winter reflects bears denning and fewer people outdoors in equal measure, which is why the agency’s sentences below, not the curve, carry the timing.
2,085 research grade American black bear observations have been uploaded to iNaturalist for Colorado across every year the platform holds, and 22 percent of them fall in the three shaded fall months. The busiest month in the record is July, and reports drop below 40 percent of that peak by October. These are counts of what people reported, so they measure observers as well as bears; they are not a population, not a survey and not a statement about this autumn. See the records on iNaturalist.
Research grade black bear reports uploaded for Colorado by year, 2016 to 2025: 44 in 2016 and 310 in 2025. Most of the climb is the platform itself growing, and every species on it shows the same shape, so this is a record of reporting rather than a population trend.

Fall feeding

Denning

When conflicts and sightings rise
In late summer through fall hyperphagia, bears will eat up to 20,000 calories per day to sustain themselves through the winter torpor period. CPW receives the most sightings and conflict reports during this time because bears are more active and visible in human spaces.Colorado Parks and Wildlife, read September 19, 2026.
