One of the biggest draws of Denali National Park is definitely the possibility of seeing wildlife. With only one 90-mile road in a park the size of Massachusetts, people are definitely outnumbered here. The tour and shuttle buses (the only way of traveling beyond mile-15 for the general public) stop frequently for all sorts of animals. With very limited human interaction, this is one of the few places you can see all bears, lynx, wolves, coyotes, moose, and caribou up close in their natural habitat.
We saw this grizzly from the bus. I also frequently see them while hiking in the park, usually far away on the tundra (as close as I want to be). Often they just look like brown blobs meandering around a hill. A few times on the shuttle I’ve had the opportunity of seeing them real close, only about 15-20 feet away. I sat and watched this one for probably 15 minutes, devouring every berry in its path. Look at the claws! It’s an absolutely incredible experience, I highly recommend visiting.
