Pack smart. Don't bring any food on your hike that possesses a strong smell, such as fish, eggs, or bacon. Don't bring toiletries that have strong fragrances either. Don't leave food out in the open or in tents.
Use bear-resistant containers. A bear-resistant container is one which a bear cannot open or break into. You can rent or buy bear-resistant containers at outdoor shops or special sporting goods supply stores. Hang food in a tree in a strong bag with cord at least 10 feet off the ground and four feet away from the trunk.
Hike intelligently. Hike in groups of three or more; grizzly bears rarely attack groups that size. Avoid peak times when bears are more on the go, such as dusk, dawn and after dark.
Make noise. By talking, laughing, singing, or clapping your hands, you are signalling your presence to bears who will then most likely try to avoid you. Don't try whistling as grizzlies sometimes mistake that for the sound of animals and it draws them closer.
Cook 100 feet away from the area where you intend to sleep. Don't sleep in the clothes that you wore while cooking.
