Grizzly bears live mainly on the open tundra. Most bears seen by visitors along the park road are grizzlies, or brown bears. The bears of Denali are wild creatures, free to behave as they wish. If annoyed, these solitary animals can be very dangerous to intruders. Be alert at all times, in all places.
Bears are active both day and night and can be found anywhere.
Watch for their tracks and scat. Avoid surprising bears. They may perceive you as a threat if you startle them. Sing, shout, or make other loud noises as you walk to warn bears of your presence. Be especially careful in dense brush, where visibility is low, and along rivers, where bears cannot hear you over the noise of the water.
