2. Watch For Bears At Yellowstone National Park, USA

Yellowstone National Park covers an area in three states: Wyoming, Montana, and Idaho. Here among incredible giant redwood trees, live both grizzly and black bears. You might not see one, but if you do, keep your distance, make noise to let the bear know you’re there, and don’t panic.
Black bears are generally smaller and more prone to run from humans. Grizzly bears are more aggressive. Take your pictures from a safe distance!
