Stay on marked trails or paths. Think clearly about the potential consequences of your actions. If you are hiking through bear country, make your presence known - especially where the terrain or vegetation makes it hard to see. Make noise, sing, talk loudly or tie a bell to your pack. If possible, travel with a group.
Groups are noisier and easier for bears to detect.
Avoid thick brush. Contrary to popular belief, bears can see almost as well as people, but trust their noses much more than their eyes or ears. Always let bears know you are there. Bears, like humans, use trails and roads. Don't set up camp close to a trail they might use.
