Yellowstone is home to the largest concentration of mammals in the lower 48 states. Sixty-seven different mammals live here, including grizzly bears, black bears, gray wolves, wolverine, linx, elk, bison, moose, and numerous small mammals.
View all wildlife safely. You must stay at least 100 yards (91 m) away from bears and wolves and at least 25 yards (23 m) away from all other animals—including bison, elk, bighorn sheep, deer, moose, and coyotes. Visit our Wildlife Viewing page for more information.
