Bison in Yellowstone Park

Viewing wildlife is one reason many people head outside. Seeing a large bird soaring overhead or a herd of bison grazing in a distant meadow can turn a simple outing into an adventure you’ll never forget. But, up-close encounters, while certainly memorable, can be bothersome (think small mouse stealing food from your pack) or even dangerous (think giant grizzly bear in the middle of the trail) and are best avoided to keep both you and the wildlife safe.

This article provides tips on preventing unwanted run-ins with most types of animals and specific information about handling encounters with black bears, grizzly bears, cougars, bison, mountain goats, moose, elk and snakes. If bugs are your worry and you want to learn about encounters with mosquitoes, bees, spiders and scorpions, see our article How to Treat Insect Bites and Stings.


How to Reduce Wildlife Encounters

These tips apply to many types of wildlife, so whether you’re concerned about encounters with potentially dangerous animals, like bears and cougars, or less-threatening ones, such as mice, skunks, racoons and deer, it’s recommended that you follow them.

Properly store food and other scented items: Leaving food and scented items unattended is like putting up a welcome sign for animals. This includes empty food containers, trash, cookware, toiletries, lotions and all other scented things. If you’re car camping, store food in a cooler and/or car during the day. At night, put everything in your vehicle or a metal bear locker. In the backcountry, store things in a bear canister, bear bag or metal food locker, or hang them in a bag from a tree or pole, when you’re not using them. Learn more in our article Food Storage and Handling for Campers and Backpackers.

Keep odors away from camp: Cook your food and wash your dishes well away from your camp so as not to attract wildlife to where you sleep.

Give animals space: Many animals will not willingly attack unless they feel threatened or provoked. One of the best ways to prevent this is to stay a safe distance away. Doing so not only helps reduce potentially dangerous encounters, it’s also what’s best for the animal—approaching wildlife can cause them stress and force them to waste valuable energy. The appropriate distance varies by species, but one way to think about it is if your presence causes an animal to move, then you’re too close. Yellowstone National Park says to stay at least 100 yards away from bears and wolves, and 25 yards away from all other wildlife. Of course, in a surprise encounter, this may not be possible, but if you see wildlife from a distance, be thoughtful about how close you get.

Stay aware: Use your eyes, ears and nose to stay aware of your surroundings. Doing so can help you head off close encounters. Don’t wear headphones while hiking so you're able to hear what’s happening around you.

Make noise while you hike: To avoid surprising a bear or other potentially threatening animal on the trail, make noise while you’re hiking. You can shout, “Hey bear!” every few minutes, talk or sing loudly with your fellow hikers, clap your hands or strike your trekking poles together. Some hikers wear bear bells, though they may not be loud enough to be useful.

Avoid hiking at dawn or dusk when animals, including bears, are most active. In cougar country, avoid hiking after dark.

Follow Leave No Trace principles: Properly dispose of human waste to avoid attracting critters, and respect wildlife by observing them from a distance and never feeding them.

Research the area you’ll be traveling in: Knowing something about the wildlife you’re likely to encounter will help you be informed about tactics for preventing encounters, and let you know the best way to respond if you do have a run-in. Websites for national parks and other land management agencies can be very helpful.


What to Do if You Encounter a Bear

Our comprehensive article Backpacking in Bear Country details what to do when you encounter a bear, so we recommend reading that. But here’s the gist: Bears will generally flee when they sense your presence. However, bears can be unpredictable and, in some situations, dangerous. Always leave plenty of space between you and a bear if possible.

How you respond to a bear encounter can be different depending on whether you run into a black bear or a grizzly bear, so it’s beneficial to be able to tell them apart. Black bears live throughout much of the country, have no shoulder hump and have a straight face profile. Grizzly bears are found in Wyoming, Montana, Idaho, Alaska and western Canada. They have a distinctive shoulder hump, small rounded ears and a concave face profile. Black bears and grizzlies can both range in color from blonde to black, which can sometimes make it difficult to tell them apart.


What to Do if You Encounter Either Type of Bear

  • Never approach a bear.
  • If you see cubs, be especially cautious and stay away. Mother bears can be very protective of their young.
  • If you see the bear before it sees you, back away slowly, keeping your eyes on the bear.
  • Retreat and/or reroute to give the bear a wide berth.
  • If you have bear spray, get it ready.


What to Do if You Encounter a Black Bear

  • If the bear is coming toward you, raise your arms to look larger and make lots of noise by yelling and banging pots together. Throw objects to scare it off.
  • If you have food out, quickly secure it in a bear canister or carry it with you as you back away. It’s important to keep the bear from getting your food.
  • If the bear continues to pursue you and seems more interested in the food than you, ditch the food as a last resort and move away.
  • Even if the bear seems harmless, try to scare it off and move away.

If a black bear attacks:

  • Do not play dead.
  • Fight back by using sticks, rocks and punches on its eyes and nose.


What to Do if You Encounter a Grizzly Bear

  • You don’t want to appear as a threat, so stay calm, back up slowly and don’t make eye contact.
  • If the grizzly does a bluff charge, try not to panic. The bear will be huffing and bounding, and its ears will be up. Talk to the bear in a friendly tone. Grab your bear spray, but do not turn and run. If the bear retreats after the charge, continue to back up.

If a grizzly bear attacks:

  • Signs of an impending attack include ears that lie flat and head that is held low while the bear charges. Activate your bear spray when the grizzly reaches 30 feet from you. Don’t panic and spray too soon.
  • Play dead if you don’t have bear spray or it fails to deter the bear.
  • To play dead, lie flat on your stomach. Put your backpack between you and bear. Use your hands to cover the back of your neck.
  • If you get rolled over, try to keep rolling so you end up back on your stomach.


What to Do if You Encounter a Cougar

Cougars, also known as mountain lions or pumas, are secretive animals that are rarely seen in the wild. In North America, they’re found throughout much of the western U.S. and Canada and occasionally in eastern states and provinces. When they do encounter a human, they will typically retreat if able to; attacks are very rare. If you encounter a cougar, here’s what to do:

  • Never approach a cougar.
  • Stop and don’t run. Running may trigger the animal’s instinct to attack.
  • Pick up small children or move them behind you.
  • Face the cougar and don’t take your eyes off it.
  • Try to appear larger than the cougar by raising your arms or swinging a jacket around above your head. You can even stand on something to make yourself taller.
  • Talk to it firmly while slowly backing away.
  • If the cougar appears aggressive and moves toward you, shout and throw things to try to make the cougar realize you’re a potential danger.

If a cougar attacks:

  • Fight back.
  • Try to stay on your feet and be aggressive.
  • Use whatever you can to beat back the cougar, such as sticks, rocks, water bottles, backpacks and your bare hands.
  • If you have bear spray, aim for the cougar’s face.


What to Do if You Encounter Bison

Bison are the largest land-dwelling mammal in North America, weighing up to 2,000 pounds. In the wild, they can be found in western states such as Wyoming, Montana, North Dakota and South Dakota. Bison may appear tame and docile, but they are unpredictable and incredibly fast—they can run up to 40 mph. They generally won’t attack unless provoked, but you need to be very cautious—in Yellowstone National Park, bison have injured more humans than any other animal. Here’s what to do if you encounter bison:

  • Never approach bison. Always stay at least 25 yards away.
  • Never try to scare or chase them away.
  • Wait for bison to leave the area, walk around them leaving plenty of room or back away slowly.
  • Look for warning signs that bison are upset. These include snorting, tossing their heads, raising their tails, pawing the ground, making eye contact and false charging.
  • If you’re in a car and bison are in the roadway, drive slowly and they will typically move.

If a bison attacks:

  • If possible, find protection in a car or behind a boulder or tree.
  • Protect your head and neck.
  • Move away when possible.


What to Do if You Encounter a Mountain Goat

Mountain goats inhabit the mountain regions of northwest North America, including in Alaska, Washington, Idaho, Montana and British Columbia and Alberta, Canada. They primarily spend their time in alpine and subalpine environments. Mountain goats typically shy away from contact with humans, but they can learn to associate people as a source of minerals through sweat and urine and thus approach and follow people closely. You can help prevent close encounters and possible habituation by not allowing them to lick sweat-soaked gear and never urinating within 50 yards of a hiking trail.

Attacks by mountain goats are very rare, but if you run into a mountain goat, here’s what to do:

  • Stay at least 50 yards away.
  • If a mountain goat approaches you, slowly move away to keep a safe distance.
  • If it continues to come toward you, try to chase it off by yelling, making loud noises, waving clothing or throwing rocks.

If a mountain goat attacks:

  • Move away and avoid contact with the sharp horns.
  • If necessary, use whatever you can to beat the mountain goat back.


What to Do if You Encounter a Moose

Moose are hulking animals found throughout much of northern North America, including in Canada, much of Alaska, upstate New York, northern New England, the Rocky Mountains and northern parts of Minnesota, Wisconsin and Michigan. Moose aren’t typically aggressive, but if they sense a threat they will defend themselves. If you encounter a moose, here’s what to do:

  • If the moose doesn’t see you, stay quiet and try to move away undetected.
  • If it does see you, talk to it softly and move away slowly.
  • Don’t be aggressive.
  • Look for signs that the moose is upset, such as ears laid back and raised hair on its back and shoulders. These things may indicate that the moose is ready to attack.

If a moose attacks:

  • When a moose charges, it’s often a bluff. But, take it seriously and get behind something, such as a tree or boulder.
  • If there’s nowhere to hide, run. Moose typically won’t chase you very far.
  • If a moose knocks you to the ground, curl up in a ball with your hands wrapped around your head. Don’t fight back; doing so may encourage the moose to continue its attack.


What to Do if You Encounter Elk


Elk are big animals—females can weigh 500 pounds and males 700 pounds—and they can attack if they feel threatened. Elk can be particularly aggressive during mating season, which is generally in the fall. They are found primarily in western North America, in mountainous landscapes. If you encounter elk, here’s what to do:

  • Keep your distance; aim to keep 50 yards between you and them.
  • Never touch or move elk calves.
  • If an elk approaches you, back away slowly. Give the animal space and allow it to pass.

If an elk attacks:

  • When the animal charges, don’t turn your back.
  • Find protection behind a tree, boulder or vehicle.
  • Protect your head and neck.


What to Do if You Encounter a Snake

Snakes are generally nonconfrontational when left undisturbed. And, in many cases, they are nonvenomous and therefore pose little risk. But, if you surprise a venomous snake, such as a rattlesnake, or one that you can’t positively identify as nonvenomous, then you should proceed with caution. If you encounter a snake:

  • Stop moving. Stay calm.
  • Slowly back away.
  • Look for an alternate route that gives the snake a wide berth.

If a snake bites you:

  • Stay calm—activity can increase the absorption of venom.
  • Clean the wound with soap.
  • If possible, limit activity by having someone help to carry you out.
  • Get to a hospital ASAP for a complete evaluation.
