I hike about 1,000 miles annually in the Rocky Mountains. I normally meet at least one black bear on trail each year. You can increase your opportunities by hiking at dawn and dusk. Also, you should look for bear scat. I found blueberry-filled scat two weeks ago. However, the only wildlife that I encountered was a single wolf howling at me after I had been whistling in the dark on a trail about twelve miles into the Eagles Nest Wilderness Area. If you want to meet a brown bear, the grizzlies that fish at Brooks Falls in Katmai National Park are very polite. I photographed at least twenty every day, about a thousand photographs per day. Acadia National Park has a greater concentration of black bears than the Rocky Mountains because the eastern forest and wetlands are more productive with food-bearing plants. Therefore, you should be able to easily able to find a bear. I have always found more bears in developed campgrounds and small towns because bears become habituated to the easy pickings that people leave behind. I have never had a bear walk through my dispersed campsites, since the areas are less visited by people and backpackers leave behind less food. Camp near wetland areas where there are game trails, since wetland areas generate more food than dense, dry forests.
