The best place for bear-viewing in Alaska is Katmai National Park and Preserve. Katmai is so remote that it is only accessible by air. Unfortunately, due to bad weather the booked flight was cancelled. I took these pictures inside a tour bus with a 400mm lenses while visiting Denali National Park. Denali National Park is very huge (9,492 square miles), but currently there are only 300-350 grizzly bears and 200 black bears roaming around the park. Because the number of bears is low, it is very unusual to see three bears at once. I visited Alaska in early July. Sadly, at the same time a female camper was killed by a grizzly bear in Montana. A bear pulled the woman from her tent in the middle of the night though her friends tried to rescue her using bear spray. Needless to say, I stayed inside the tour bus and now I have a good reason to buy a 600mm telephoto lenses or a drone!
