Just like the cuddly ones, they come in many colours: black, blonde, cinnamon or brown. But theyíre not so cuddly. And then there is the somewhat unique grizzly as well, which can be blonde to reddish to dark brown. But you canít miss a grizzly, as they can be as much as 2.5 metres tall. Grizzlies are only in the far north of the US now, and can be seen in Glacier National Park in Montana although sightings are rare. Not everyone wants to see a bear, of course, but if you are careful, it is very rare for a brown or black bear to attack a human. They can be seen in the Rocky Mountain National Park, Yosemite and Yellowstone, to name but a few.
