It's one of the best places in the world to observe wild bears. Inhabited by both black bears and grizzly bears, Yellowstone is a bear-watcher's paradise. For many people, seeing bears is one of the main reasons they come to Yellowstone. It's possible to see ten or fifteen bears in one day in this vast preserve.

In 2026, your likelihood of seeing a bear in Yellowstone is relatively high, provided you visit the right areas at the right times. While there are no guarantees in the wild, the park's bear population is thriving. The best chances are in the Lamar and Hayden Valleys, often called the "Serengeti of North America." In these wide-open spaces, grizzlies and black bears are frequently spotted, especially during the early morning and late evening (dawn and dusk) when they are most active. In May and June, sightings are even more common as bears move to lower elevations to find food after hibernation. Many visitors see at least one bear during a three-day trip, often during a "bear jam"—a traffic backup caused by a bear visible from the road. To increase your odds, bring high-quality binoculars or a spotting scope. By 2026, the park has also completed installing bear-proof food storage in 100% of campsites, which helps keep bears wild and visible in their natural habitats rather than lurking near humans. Always maintain a distance of at least 100 yards (91 meters) for your safety and theirs.
