Do not make abrupt moves or noises that might startle it. If you cannot detour, wait until the bear moves away from your route. Do not try to approach it for a better look or a picture. Female bears with cubs or bears defending a carcass are extremely dangerous - be alert and respectful. Hike in groups and make noise.
Many experienced hikers wear bells, whistle, talk loudly, or sing.
Keep your sleeping gear clean and free of food odor and sleep at least 100 yards from your cooking area. Seal all food, as well as toothpaste, makeup, and clothes worn while cooking, in plastic bags. Then hang the bundle at least 10 feet above the ground and at least 4 feet horizontally from any post or tree trunk.
