COLORADO — Colorado Parks and Wildlife (CPW) is warning outdoor enthusiasts to be especially vigilant while recreating in areas with moose following three recent attacks involving cow moose in Park, Grand, and Routt counties.
The attacks, which occurred between May 30 and June 1, highlight the increased aggression of cow moose during calving season. Calving season, which runs from late spring through early summer, can make cow moose more protective and prone to aggression if they perceive a threat to their young. CPW officials are reminding hikers and outdoor visitors to respect wildlife and remain alert, especially in thick vegetation near rivers, lakes, and willows, where moose are often found and can be difficult to see.
Here are overviews of the three recent incidents in Fairplay, Grand Lake, and Steamboat Springs, Colorado:

Summary of Recent Attacks
Fairplay (May 30): Two women were walking four dogs off-leash along Fourmile Creek Road when they were repeatedly charged and trampled by a cow moose. They managed to escape by climbing onto a nearby roof, and a neighbor was able to haze the moose away with a fire extinguisher. CPW officers found two cow moose in the area but couldn’t identify which was involved, so no action was taken.
Grand Lake (May 31): A couple returning home from a walk with their dog encountered a cow moose near Columbine Lake. The moose charged the woman, causing injuries to her face, shoulder, and arms. Her boyfriend ultimately shot the moose in self-defense. CPW later found and euthanized the calf, citing concerns about the calf’s long-term survival if rehabilitated due to its young age and lack of natural survival skills.
Steamboat Springs (June 1): A woman walking two dogs at River Creek Park was attacked by a cow moose. A nearby paddleboarder assisted her, but the moose returned and kicked him as well. The woman sustained serious injuries and was transported to a hospital on the Front Range, while the man was treated at the scene. Both dogs were on-leash during the incident.
Stay Safe in Moose Habitat
CPW reminds everyone recreating in moose territory to:
Keep dogs on-leash at all times to reduce the risk of startling moose.
Be extra cautious near riparian and willow habitats with thick vegetation.
If you see a moose calf, leave the area immediately—cow moose will be nearby and highly protective.
If a moose charges, put an obstacle like a tree or boulder between you and the animal.
Pay attention to posted signs warning of moose presence and avoid trails with poor visibility.
Moose conflicts remain rare, with only 22 injuries reported since 2019. However, as these recent attacks show, cow moose can be aggressive, particularly during calving season. Outdoor enthusiasts are urged to report any moose conflicts to their local CPW office and to recreate responsibly to help protect both themselves and Colorado’s wildlife.
