Two hikers were injured in a bear attack on Monday afternoon along the Mystic Falls Trail near Yellowstone National Park’s Old Faithful geyser, park officials confirmed Tuesday. The incident prompted the temporary closure of a large area, including at least five trails and several backcountry campsites, as authorities investigate the encounter involving one or more bears. The species of the bear(s) has not been confirmed, though Yellowstone is home to both grizzly and black bears. Officials did not disclose the hikers’ conditions or whether they were traveling together.
The attack marks the first bear-related injury in Yellowstone this year. The last similar incident occurred in September 2025, when a hiker was seriously injured on the Turbid Lake Trail. The most recent fatal bear attack inside the park happened in 2015, though a grizzly killed a woman just west of Yellowstone in 2023. Park officials emphasized that bear attacks remain rare, with over 4 million visitors annually.
Investigation and Safety Measures
Park officials have not yet determined whether the attack was predatory or defensive. The fate of any bear involved will depend on the circumstances of the encounter. In past cases, bears exhibiting abnormal behavior, such as consuming human remains, have been euthanized, while those involved in surprise encounters have been left unharmed. The park advises visitors to maintain a 100-yard distance from bears, carry bear spray, and remain vigilant for signs of bear activity.
Bear Population and Conservation
Yellowstone’s grizzly bear population has rebounded significantly since the 1970s, when it dropped to just 136. Conservation efforts have expanded their habitat to over 27,000 square miles across Wyoming, Montana, and Idaho. Grizzlies remain listed as threatened under the Endangered Species Act, though their population is now considered stable. The first grizzly sighting of 2026 was reported in March, signaling the end of hibernation season.
Visitor Safety Reminders
The park has reiterated safety guidelines, urging hikers to avoid surprising bears by making noise, staying on marked trails, and carrying bear spray. Officials also recommend checking for recent bear activity, such as tracks or feeding sites, before venturing into backcountry areas.
