(News Release) On March 9, Yellowstone biologists working in the northern part of the park reported seeing the first grizzly bear of the spring season. The bear was observed in the backcountry scavenging on a bull bison carcass.
The first reported grizzly bear sighting of 2025 occurred on March 14. In 2024, it occurred on March 3, and in 2022 and 2023, March 7.
When bears emerge from hibernation, they look for food and often feed on elk and bison that died over the winter. Bears may react aggressively to encounters with people when feeding on carcasses. Male grizzlies come out of hibernation in early March. Females with cubs emerge in April and early May.
All of Yellowstone is grizzly and black bear country: from the deepest backcountry to the boardwalks and parking lots around Old Faithful. Protect yourself and bears by following our safety guidelines:
🐻Prepare for a bear encounter by carrying bear spray, knowing how to use it and making sure it’s accessible.
🐻Stay alert.
🐻Hike or ski in groups of three or more, stay on maintained trails and make noise. Avoid hiking at dusk, dawn or at night.
🐻Do not run if you encounter a bear.
🐻Stay 100 yards (91 m) away from black and grizzly bears. Approaching bears within 100 yards is prohibited. Use binoculars, a telescope or telephoto lens to get a closer look.
🐻Store food, garbage, barbecue grills and other attractants in hard-sided vehicles or bear-proof food storage boxes.
🐻Report bear sightings and encounters to a park ranger immediately.
