Hidden danger at popular US national park forces trail closures as bear sightings climb

Officials said closures are put in place when bears frequent specific areas or show signs of unpredictable behavior, posing a risk to both visitors and wildlife.

The Smokies are home to roughly 1,900 black bears, one of the densest populations in the country, the National Park Service said.

Park officials say human behavior is also contributing to the problem.

Park officials are also urging visitors to know how to respond if they encounter a bear.

If a bear notices you and changes its behavior, such as stopping or moving toward you, officials say you are too close and should slowly back away while facing the animal.
