Two hikers are injured after a bear attack on Monday afternoon on the Mystic Falls Trail near Yellowstone National Park’s Old Faithful area, according to National Park Service officials and multiple news outlets. The NPS says the injuries were sustained on the trail by “one or more bears” and does not specify the bear species. The incident leads to closures in the surrounding area, including parts of trails and a campsite, as park officials investigate what happened and assess safety conditions. Several reports say affected trails and nearby areas remain closed after the attack, with reopening decisions tied to the investigation and ongoing risk management. The attack is described consistently as occurring along the Mystic Falls Trail, a popular route near Old Faithful. One outlet notes the trail had previously been closed until 2024 as part of efforts to reduce conflicts with grizzly bears, before it was reopened. No reports in the provided accounts describe the hikers’ conditions in detail or identify the bears involved.
