Wildlife in Yellowstone National Park (2025 Guide)

Yellowstone is one of the best places in the world to see wild animals in their natural habitat. The park is home to bison, elk, wolves, bears, moose, pronghorn, eagles, and much more. Here’s how to make the most of your wildlife watching adventure in 2025:

Iconic Animals to Spot

Bison: The largest land mammal in North America. Look for herds in Lamar and Hayden Valleys. Watch for “bison jams” on park roads!
Elk: Common throughout the park, especially in the northern range. Fall is rutting season—listen for bugling males.
Wolves: Reintroduced in 1995, wolves are most often seen in Lamar Valley, especially at dawn and dusk.
Grizzly and Black Bears: Grizzlies prefer higher elevations; black bears are more common in forests. Spring and early summer are best for sightings.
Moose: Most often found in marshy areas near the park’s southern border.
Pronghorn, coyotes, foxes, eagles, otters, and more: Yellowstone’s diversity is unmatched!

Best Places & Times for Wildlife Viewing

Lamar Valley: Known as the “Serengeti of North America” for its abundance of wildlife—especially wolves, bison, and bears.
Hayden Valley: Excellent for bison, elk, and birdwatching.
Mammoth Hot Springs area: Elk are often seen grazing on the lawns.
Early morning and late evening: Animals are most active at dawn and dusk.
Spring (April–June): Best for seeing baby animals and bears emerging from hibernation.
Fall (September–October): Elk rutting season and bears foraging for winter.
Winter: Wolves, bison, and other hardy species are easier to spot against the snow.

Wildlife Watching Tips

Bring binoculars or a telephoto lens for safe, close-up views.
Stay at least 100 yards from bears and wolves, 25 yards from all other animals.
Never approach, feed, or disturb wildlife—keep them wild!
Learn animal behavior: raised tails, head-shaking, or agitation are signs to back away.
Ask park rangers for the latest wildlife sightings and safety updates.
Dress in layers and be prepared for early mornings and cool evenings.
Be patient—wildlife viewing is unpredictable, but rewarding!

Safety First

Carry bear spray and know how to use it.
Stay on roads, boardwalks, and marked trails.
Do not run if you encounter a bear—back away slowly and speak calmly.
Follow all park regulations and ranger advice.
