Driving

Traffic-related accidents are the most common cause of injury and death in the park. Don't let the scenery distract you—drive cautiously and watch for animals. 

 

   

Thermal Areas

Grand Prismatic Spring in Yellowstone National Park

Burns from thermal features are a common cause of serious injury and death in the park. The ground surrounding these features may look solid, but it can be just a thin crust with super-heated water below.

 

   

All Wildlife

Animals in Yellowstone National Park are wild and dangerous. Follow these regulations and guidelines to keep yourself, and the wildlife you may encounter, safe.

 

   

Bears

All of Yellowstone is grizzly and black bear country, from the trails in the park’s backcountry to the boardwalks and parking lots around Old Faithful. Your safety cannot be guaranteed, but you can play an active role in protecting yourself and the bears people come here to enjoy.

 

   

Bison

Bison may appear tranquil, but these large animals have injured more people in Yellowstone than any other animal. They are unpredictable and can run 3x faster than humans, making it very important to give them plenty of space. 

 

   

Elk

With their large antlers, it's easy to see why bull (male) elk are dangerous, but cow (female) elk are just as dangerous when protecting their calves in the spring.

 

   

Wolves & Cougars

While wolves and cougars (mountain lions) are skilled predators, they are not normally a danger to people, and very few documented confrontations with humans have occured in Yellowstone. It's still important, however, to know what to do if you encounter them.
