We have resided in Estes Park, Colorado over 5 years and have never seen a mountain lion. We have however seen mountain lion tracks in the snow. Mountain lions are mostly out at night. However, on rare occasions they can be observed during the day. Mountain lions most often hunt deer and elk. Based on mountain lion tracking results, a mountain lions can travel over 100 miles in a month.
People encounter mountain lions only on rare occasions. Mountain lions can be most aggressive when they have cubs or are feeding. Never approach a mountain lion. They need a way to escape. Never run from a mountain lion. If you can back away slowly, do so and stay calm. Try to make yourself look larger to convince the mountain lion that you are not prey and to leave you alone.
If a mountain lion becomes aggressive, do everything in your power to deter the lion including standing upright, waving your arms, throwing rocks and speaking firmly. If you are attacked, fight back. Remain standing and get back up if you are down.
Mountain lions are magnificent animals and should be respected.
