In bear country, it is a good idea to wear small silver bells to warn bears of your approach.
It is also a good idea to carry pepper spray, in case you still surprise the bear, and need to defend yourself.
Hikers should also be on the lookout for bear faeces, as this is often the first warning of bears in the area.
Black bear faeces are generally smaller, smells of fish, and usually contains berries.
Grizzly bear faeces are quite large, smells like pepper, and often contains small silver bells.
