Recent Grizzly Bear Incidents in Yellowstone and Glacier National Parks: A Closer Look
In early May 2026, both Yellowstone and Glacier National Parks experienced notable grizzly bear incidents, prompting discussions about the safety of these iconic wilderness areas.
Yellowstone National Park: Hiker Injured on Mystic Falls Trail
On May 4, 2026, two hikers sustained injuries from a bear attack along the Mystic Falls Trail near Old Faithful. The National Park Service (NPS) responded promptly, closing several trails and backcountry campsites in the Midway Geyser Basin area for investigation. While the specific species involved was not confirmed, both grizzly and black bears inhabit the region. This incident marked the first bear-related injury in Yellowstone since September 2025.

Glacier National Park: First Fatal Bear Attack in Decades
On May 6, 2026, the body of 33-year-old Anthony Pollio from Fort Lauderdale, Florida, was discovered off the Mt. Brown Trail in Glacier National Park. Authorities believe this to be the park’s first fatal bear attack since 1998. The National Park Service stated that Pollio’s injuries were consistent with those sustained from a bear encounter. In response, officials temporarily closed designated trails near Lake McDonald Lodge to assess the area for ongoing bear activity and ensure public safety. (apnews.com)
Understanding Bear Behavior and Safety Measures
Grizzly bears are known to use trails, especially during early spring when food sources are scarce. Hikers are advised to remain vigilant, make noise to alert bears of their presence, and carry bear spray. It’s also recommended to hike in groups, as larger groups are more intimidating to bears. Avoiding running from bears is crucial, as it can trigger a chase response. Additionally, staying at least 100 yards away from bears and avoiding hiking at dawn, dusk, or night—when bears are more active—can further reduce the risk of encounters. (wyomingpublicmedia.org)
