Bears often stand upright to test the wind and to see better.
Spring usually has the best weather and highest bear count. The bears will be found eating the newly sprouted green grass in the tidal flats. During the Fall, the bears can be found in streams and rivers feeding on salmon, but be sure and book early as mountain goat, moose, and deer hunts occupy most of that time of the year. No matter when you visit, there are always lots of bears to see and seafood to chase. Hunt utilizing spot and stalk method.
