Consider the millions of visitors to Denali National Park and the very low incidents of human and bear encounters. Most in fact occur when the hiker are in deep brush  and surprise  the bear. Unlike Katmai which I have been to there are not a lot of bears all in one spot in Denali since there are no salmon or any fish for that matter,  in the Park. The Grizzly bear of  Denali Park and the Coastal brown bears of Katmai are very different bears. I have spent years at Denali National Park and the National Park Service there does a great job managing the bears of the park.
