Incident Overview
On the afternoon of May 4, 2026, two hikers were injured by one or more bears on the Mystic Falls Trail, a popular route a few miles west of Old Faithful geyser in Yellowstone National Park. National Park Service (NPS) emergency crews responded and the hikers were taken for medical care; their identities and the severity of their injuries have not been released. The park classified the event as a single encounter and placed the incident under investigation. In response, the NPS temporarily closed the area west of Grand Loop Road—from the north end of Fountain Flat Drive to Black Sand Basin—including Fairy Falls Trail (north of the Grand Prismatic Overlook), Sentinel Meadows, Imperial Meadows, Fairy Creek, Summit Lake trails, five backcountry campsites (OG1-OD5), and fishing access along the Firehole River.
Recent Bear Incidents in Yellowstone
The Mystic Falls attack marks the first bear-related injury in the park for 2026. The most recent prior injury occurred in September 2025 on the Turbid Lake Trail, where a 29-year-old hiker sustained chest and arm wounds. The last fatal bear attack inside the park was in 2015, when a 63-year-old man was killed near Lake Village. A grizzly bear killed a woman just west of the park in 2023. Yellowstone hosts both grizzly and black bears; grizzlies are larger and can exhibit more aggressive behavior. Scientists documented the first grizzly of 2026 in March, signaling the start of the active season.
Data & Statistics
- Greater Yellowstone ecosystem supports more than 1,000 grizzly bears across Montana, Idaho, and Wyoming.
- Grizzly numbers fell to 136 in 1975; the population now occupies over 27,000 square miles and is considered stable.
- Visitor traffic exceeds 4 million annually.

- Closed resources: Fairy Falls Trail (north of Grand Prismatic Overlook), Sentinel Meadows, Imperial Meadows, Fairy Creek, Summit Lake, campsites OG1-OD5, and Firehole River fishing zones.
Official Statements & Responses
The NPS released a media statement confirming the single-event nature of the encounter and the ongoing investigation. Park officials reiterated standard safety protocols: maintain a minimum distance of 100 yards from bears, carry and know how to use bear spray, travel in groups of three or more, make noise while hiking, avoid dawn, dusk, and night travel, and never run from a bear. Visitors are directed to the park’s Backcountry Conditions page for up-to-date trail and campsite status.
Conflicting Reports & Gaps
- Bear species: Sources note the presence of both grizzly and black bears but have not identified which species was involved.
- Number of bears: Descriptions vary between “one or more” and “one or multiple” bears.
- Injury details: One report states the hikers were airlifted to Eastern Idaho Regional Medical Center; other outlets provide no medical specifics.
- Exact timing: All sources agree on a Monday afternoon, but only a few specify the date (May 4).
- Direct quotations: Several statements appear verbatim in multiple releases, creating overlap in phrasing.
