Hiker injured after surprise bear attack in Yellowstone

In Yellowstone National Park, a 29-year-old hiker was attacked by a bear while hiking alone on the Turbid Lake Trail on September 17, 2025. The hiker, who believed the bear to be a black bear at first, encountered the animal unexpectedly. He deployed bear spray but sustained significant injuries, including wounds to his chest and left arm. Following the attack, park medics helped him evacuate, and he was transported to the Lake Medical Clinic and subsequently flown to a nearby hospital for further treatment. The Turbid Lake Trail has been closed to ensure visitor safety while investigations into the incident are underway. Park officials suspect the bear involved was a grizzly rather than a black bear, based on its size and behavior. They plan to conduct DNA analysis to confirm the species of bear. Given that the encounter was described as a defensive reaction from the bear during a surprise meeting with the hiker, management actions against the bear are not anticipated. This incident marks the first bear-related injury in Yellowstone since May 2021, highlighting how rare such occurrences are within the park. With over 566,000 visitors recorded in May alone, safety around wildlife remains a significant concern. While park incidents involving wildlife injuries do happen occasionally, they are considered extremely rare events, with protective measures in place to reduce risks for those exploring the park's natural beauty. The park’s management emphasizes the importance of safety protocols for visitors, including the use of bear spray, safe hiking practices, and understanding wildlife behavior. Visitors are reminded of the need for precautions while enjoying the natural landscape, especially in bear habitat areas. Continued awareness and responsible behavior can help minimize risks during adventures in Yellowstone National Park.
