1. Keep noise to a minimum
Bears are very shy animals and are afraid of human encounters. The louder the group, the less likely a bear is to approach.
2. Look for signs
Bears often rub, bite or scrape trees as a way of marking their territory and leave carcasses after feeding on them. If you see any of these signs, a bear must be not too far away.
3. Watch for tracks
The width of a bear's step varies widely. On hard terrain, a bear usually walks with narrow steps. On soft and sinking terrain—such as deep snow—the bear walks with its legs clearly spread and places its front and hind legs in the same tracks.
4. Be patient and wait
Being shy animals, the best way to spot a bear is by waiting patiently from a purposely-built watching hide. They won't see you, but you will see them.
5. Always be ready
Have your camera turned on, with the correct settings and your lens cap off at all times. You never know when a bear will show up.
