Violent bears must be destroyed. Please, for their sake and yours, do not feed the bears. Although there is no one best place to see bears in the Park, Cades Cove and the Roaring Fork Motor Nature Trail are among the best spots to look. Bears are most active early in the morning and late in the evening. Only when between a mother and her cubs, or when dealing with a hungry, human-fed bear are they dangerous.
Bears are excellent climbers, so climbing a tree is ineffective.
Playing dead does not work either, since dead animals are part of the black bears' diet. However, few dangerous bear situations occur.
