Cougar in Rocky Mountain National Park Travel Postcard

Rocky Mountain National Park in Colorado is a dramatic landscape of alpine tundra, dense coniferous forests, and glacier-carved peaks that rise above 14,000 feet. Spanning over 415 square miles, the park is home to a wide array of wildlife, including elk, black bears, bighorn sheep, and a more elusive predator—the cougar, also known as the mountain lion or puma. While most visitors come for the scenic vistas, hiking trails, and iconic Trail Ridge Road, the park's role as prime habitat for these big cats is less well-known but ecologically vital. Cougars in Rocky Mountain National Park are top predators that help maintain balance in the ecosystem by regulating deer and elk populations. Solitary and highly elusive, they are rarely seen by visitors, preferring remote, forested areas and rocky terrain where they can stalk prey undetected. Although sightings are uncommon, signs of their presence—tracks, scat, or deer carcasses—can occasionally be found by observant hikers or rangers. The park’s dense backcountry offers ideal cover for cougars, and their continued survival in this protected environment reflects the health of the broader wilderness. For those hiking in cougar country, it’s important to stay alert, travel in groups when possible, and know how to respond in the rare event of an encounter.
