Katmai National Park and Preserve
This was brought to the attention of rangers at Katmai National Park because it’s a great example of what NOT to do when encountering a bear on trail. As other commenters have noted, everyone arriving at Brooks Camp immediately attends a bear orientation that discusses in detail what to do in this kind of situation. The right thing to do is, first, put your camera down and pay attention. You’re dealing with a very large and potentially very dangerous wild animal. Second, back away slowly to maintain a distance of 50 yards from the bear. If the bear continues towards you, as shown in this video, you need to move off the trail and yield the right of way.

Brooks Camp is world famous for bear viewing and photography, but the only reason Katmai can allow people to have such close proximity to the bears is because the vast majority of our visitors behave responsibly and in accordance with what they’re taught at the bear orientation. Failure to act appropriately in bear country—as unfortunately is shown here—can end in disaster for both the people and the bears involved
