Solo hiker injured by bear in Yellowstone National Park

News and Adventure from Glacier National Park

On the afternoon of Tuesday, Sept. 16, a male, age 29, sustained injuries from a bear while hiking on the Turbid Lake Trail, located northeast of Mary Bay in Yellowstone Lake. The incident occurred approximately 2.5 miles from the Pelican Valley Trailhead in the Pelican Valley Bear Management Area.

The male was hiking alone when he encountered the bear near Turbid Lake. The hiker began to deploy bear spray when the bear made contact, and he sustained significant but non-life-threatening injuries to his chest and left arm. National Park Service medics responded to the incident and walked out with the hiker. Once arriving to the trailhead, NPS transported the hiker in a park ambulance to the Lake Medical Clinic. He was then flown to a nearby hospital for treatment.

The hiker thought the bear was a black bear; however, the location, size, and behavior of the described bear suggest it might have been a grizzly bear. Bear management staff will attempt to confirm the species through DNA analysis, if possible.

The Turbid Lake Trail is closed until further notice. Bear management staff are sweeping the trail to ensure no other hikers are on the trail.

This is the first incident of a bear injuring a person in Yellowstone in 2025. The last incident was in May 2021 when a grizzly bear injured a solo hiker on the Beaver Ponds Trail in Mammoth Hot Springs.
