Part of what makes the Colorado high country special is who else lives here. A bull elk bugling across a meadow, a moose wading a willow wetland, a bighorn picking across a cliff — these are trip-defining moments, and you do not need to be an expert to find them. A little know-how about where and when to look, plus a decent pair of binoculars, goes a long way.
Colorado wildlife viewing at a glance
| Top species | Moose, elk, bighorn sheep, mule deer, pika & marmots, foxes, raptors & songbirds |
|---|---|
| Best times | Dawn and dusk; the fall elk rut (Sept–Oct); winter for bighorn |
| Signature spots | RMNP (elk), Georgetown (bighorn), Silverthorne-area willows (moose), alpine tundra (pika) |
| The golden rule | Keep your distance, never feed wildlife, and use binoculars or a zoom instead of stepping closer |
What you can see
- Moose. Increasingly common in willow wetlands and lakeshores around Silverthorne, Grand County, and the west side of RMNP. Magnificent — and the animal most likely to hurt you (see safety below).
- Elk. Big herds graze meadows at dawn and dusk; the fall rut, when bulls bugle and spar, is one of Colorado’s great wildlife spectacles, especially around Estes Park and RMNP.
- Bighorn sheep. Colorado’s state animal, best spotted on rocky slopes and canyon walls — the Georgetown viewing area right off I-70 is one of the most reliable places in the state, especially in winter.
- Pika & marmots. Above treeline on the tundra (think 14er talus and Trail Ridge Road), the tiny, squeaking pika and the fat, whistling marmot are alpine favorites.
- And more. Mule deer everywhere, red foxes and coyotes, the occasional black bear, and abundant birds from dippers on the creeks to raptors overhead.
Where and when to go
Timing beats everything: most mammals are active at dawn and dusk and bed down midday. Fall means the elk rut and, conveniently, peak aspen colors — a perfect combined trip. Winter pushes bighorn and moose to more visible lower elevations. For location, the national-park meadows around Estes and RMNP, the Georgetown bighorn area, Guanella Pass, and the willow wetlands near Silverthorne are all high-percentage bets.
Watch responsibly — and safely
- Keep your distance. Use binoculars or a zoom lens, not your feet. A good rule: if the animal changes its behavior because of you, you are too close — back off.
- Never feed wildlife. It harms the animals, changes their behavior, and creates danger for the next person. Store food where bears can’t reach it.
- Moose are the real danger. They injure more people than bears do in Colorado — they’re large, fast, and unpredictable, and they especially dislike dogs. Give them 50+ feet, watch for raised hackles, pinned ears, or a lowered head, and keep dogs leashed and close (see our dog-friendly hiking guide).
- Give elk room during the rut, when bulls can be aggressive, and never get between any animal and its young.
- Tread lightly in winter, when animals are conserving energy — spooking them wastes calories they can’t spare.
Gear for wildlife viewing
The one essential is a pair of binoculars — they turn a distant speck into a bull elk and let you keep a safe, respectful distance. Our best binoculars for Colorado wildlife guide covers in-stock picks from pocket-budget to premium. Add a zoom camera for photos, and a spotting scope on a tripod if you love glassing distant cliffs for sheep.
Colorado wildlife viewing FAQ
Where can I see moose in Colorado?
Look in willow wetlands and along lakeshores — the areas around Silverthorne and Summit County, Grand County, and the Kawuneeche Valley on the west side of RMNP are all reliable. Go at dawn or dusk, and keep well back — moose are dangerous.
Where and when can I see elk?
Elk graze mountain meadows at dawn and dusk, and the fall rut (September–October) around Estes Park and RMNP is spectacular, with bulls bugling and sparring. Bring binoculars and keep your distance.
Where can I see bighorn sheep in Colorado?
Bighorn — the state animal — favor rocky slopes and canyons. The Georgetown bighorn viewing area right off I-70 is one of the most dependable spots, particularly in winter and early spring.
What is the most dangerous animal to watch out for?
Moose — they injure more people in Colorado than bears do. Give them at least 50 feet, never approach, watch for raised hackles or pinned ears, and keep dogs leashed and close. Never feed any wildlife, and give elk room during the fall rut.
