Bears are active in Grand Teton
Black and grizzly bears are roaming throughout the park--near roads, trails and in backcountry areas. Hikers and backcountry users are advised to travel in groups of three or more, make noise and carry bear spray. Visitors must stay 100 yards from bears. More »
Grand Teton National Park is home to an incredible variety of wildlife including several species of reptiles. Reptiles have dry, scaly skin and either lay eggs or bear live young. Reptiles are cold-blooded. They cannot maintain a constant body temperature like mammals. Instead they regulate their body temperature by moving into or out of sunlight. The park's cold climate limits the number of reptile species found here.
