Can bears climb trees?

All black bears can climb well. Some grizzly bears can/will climb a short distance. A tree may provide safety if it is a grizzly and you can climb to a considerable height before it reaches you. Remember, grizzly bears are unbelievably fast. Climbing a tree is usually not a good idea. It is usually better to quietly leave the area. Do not run. Running will cause the bear to instinctively chase you.
