Best Time to See Bears in Colorado: Seasonal Timing, Habitat, and Field Signs
Bears are most active in Colorado from April through October, with peak sightings in late summer as they fatten up for hibernation. The best bet is to focus on high-elevation forests and meadows in Rocky Mountain National Park and the San Juan Mountains, especially near berry patches and oak brush. Early morning and dusk offer the best viewing odds.

1. Where are bears most likely in Colorado?
Colorado's black bear population (the only bear species in the state) is concentrated in forested mountain regions. The highest densities occur in the San Juan Mountains near Durango, the Front Range foothills west of Denver, and the Grand Mesa area. Rocky Mountain National Park and the Rio Grande National Forest are reliable spots. Start by looking for oak brush, serviceberry patches, and chokecherry thickets below 9,000 feet in summer.

2. What is the best season to see bears?
Spring (April-May) bears emerge hungry and frequent south-facing slopes where snow melts early. Summer (June-August) brings bears into meadows and riparian areas for lush vegetation. Fall (September-October) is the most active time as bears enter hyperphagia, spending up to 20 hours a day feeding to pack on fat. Late September is especially good near acorn-heavy Gambel oak stands. For seasonal patterns, see ourgeneral bear behavior page.
3. What time of day are bears most active?
Bears are crepuscular, meaning most active around dawn and dusk. In summer, they may also move during midday in shaded areas. To maximize sightings, plan to be on a trail by sunrise or settle into a good viewing spot by 5 PM. During hyperphagia in fall, bears can be active all day, especially in cooler weather. Always carry binoculars and a camera with a zoom lens.
4. What field signs should beginners look for?
Tracks are a great starting point: bear prints show five toes and a distinct heel pad, often with claw marks about 1 inch ahead. Scat varies but often contains berries, seeds, or grass; in fall it can be mushy and dark from fruit. Look for clawed logs (bears tear apart stumps for insects), overturned rocks in meadows, and tree rubs: smooth patches on tree trunks where bears have scratched. Learning these signs can help you find active feeding areas.

5. How can I safely spot bears without disturbing them?
Stay on established trails, keep at least 100 yards away (about the length of a football field), and never block a bear's escape route. Use a telephoto lens or binoculars, not your phone. If you see a bear, watch for behaviors like ear flicking or huffing: those mean you're too close. Carry bear spray and know how to use it. For more tips, visit ourColorado wildlife viewing ethics page.
6. What habitat clues tell me a bear is nearby?
Look for fresh digging in moist soil (bears hunt for dandelions, clover, and grubs), broken branches on berry bushes, and large scat piles on game trails. In early summer, you might find day beds: shallow depressions under trees where bears rested. In autumn, look for corn or oats in scat if near agricultural fields. These clues signal you're in good bear country.
7. Where should I go for the best odds of a sighting?
Rocky Mountain National Park's Trail Ridge Road (especially between Rainbow Curve and Forest Canyon), the Weminuche Wilderness near Durango, and the Maroon Bells-Snowmass Wilderness are all strong options. In September, the Bears Ears area in the San Juan National Forest is productive. Always check local closures and bear activity reports at a ranger station. For a structured trip, consider a guided wildlife tour.
