If I'm out hiking, and I come around a corner and stumble upon a bear, what's the best course of action to take to minimize the chance the bear will act aggressively?

Do different types of bear (grizzly, black bear, sun bear, etc) warrant a different approach?

    Run the hell away. But remember, you don't have to outrun the bear, just the guy next to you.

    @studiohack I think that ought to be "what precautions should I have taken"

    Bears run 30 to 40 mph up hill!! So good luck out running any bear. Your best bets is talk to the bear with friendly louder voice and while facing it keep your hands in front of you and back away with same speed the bear is approaching you. If the bear takes you for pray you are done.

    Voting to close since so much depends on the circumstances. What practical, answerable question is faced here? There are great guidelines for specific bear/human interactions - especially if the bear species / geography are nailed down to make this more useful than an armchair discussion of the most general case.

    I think its tugging at a valid question - but the "startled" aspect makes it difficult... How do you know you startled the bear? Did it garumph and run away? Did it snarl and charge? The correct answer will be different for each. Below are answers to the question "How do I prevent a bear encounter from becoming a bear attack?"

Back away calmly. Be SURE not to separate a mother from her cubs. Other than that, the bear probably won't be too interested in you. (Except a polar bear, which may consider you food.)

If you see bear cubs, look for the mother and stay away.

  • @ShemSeger well add it then? My experience with a grizzly is just as the answer advises - back up quickly but calmly. I applied the advice for dogs - hold your bicycle between you and the beast - but even against a black bear that wouldn't help at all.

First of all the odds that you startle a bear in this way are quite low. There is a good chance that it would have heard or smelled you before you get that close.

That said, if you encounter a bear in the wilderness, your reaction depends on how the bear is acting. In most cases, the bear will be defensive. In this case you should stay calm, talk calmly to the bear, make yourself look big and slowly move away facing the bear, always facing it.

However, if the bear is aggressive, or is approaching you, your reaction should be different. A good guide of what to do in these situations can be found at Parks Canada's website. The page has a lot of good information, but here is the specific part on "if you see a bear":

If you see a bear

Stop and remain calm. Get ready to use your bear spray. Do not run away.

Is the bear unaware of your presence?

Move away quietly without getting its attention.

Is the bear aware of your presence?

Bears may bluff their way out of an encounter by charging and then turning away at the last second. Bears may also react defensively by woofing, growling, snapping their jaws and laying their ears back.

Stay calm. Your calm behaviour can reassure the bear. Screams or sudden movements may trigger an attack. Speak to the bear. Talk calmly and firmly. This lets the bear know you are human and not a prey animal. If a bear rears on its hind legs and waves its nose about, it is trying to identify you. Back away slowly. Never run! Running may trigger a pursuit. Make yourself appear BIG. Pick up small children and stay in a group. Do not drop your pack. It can provide protection. If you must proceed, make a wide detour around a bear or wait at a safe distance for it to move on.

If the bear approaches

Stop and remain calm. Get ready to use your bear spray. Do not run away. Assess the bear’s behaviour and determine why it is approaching.

Is it defensive?

The bear is feeding, protecting its young and/or surprised by your presence. It sees you as a threat. The bear will appear stressed or agitated and may vocalize.

  • Try to appear non-threatening.
  • Talk in a calm voice.
  • When the bear stops advancing, start slowly moving away.
  • If it keeps coming closer, stand your ground, keep talking, and use your bear spray.
  • If the bear makes contact, fall on the ground and play dead. Lie still and wait for the bear to leave.

Is it non-defensive?

A bear may be curious, after your food, or testing its dominance. In the rarest case, it might be predatory–seeing you as potential prey. All of these non-defensive behaviours can appear similar and should not be confused with defensive behaviours.

The bear will be intent on you with head and ears up.

  • Talk in a firm voice. Move out of the bear’s path.
  • If it follows you, stop and stand your ground.
  • Shout and act aggressively.
  • Try to intimidate the bear.
  • If it approaches closely, use your bear spray.

Handling an attack

Most encounters with bears end without injury. If a bear actually makes contact, you may increase your chances of survival by following these guidelines. In general, there are 2 kinds of attack:


This is the most COMMON type of attack.

  • Use your bear spray.
  • If the bear makes contact with you: PLAY DEAD!

    Lie on your stomach with legs apart and position your arms so that your hands are crossed behind your neck. This position makes you less vulnerable to being flipped over and protects your face, the back of your head and neck. Remain still until you are sure the bear has left the area.

These defensive attacks are generally less than two minutes in duration. If the attack continues, it may mean it has shifted from defensive to predatory—FIGHT BACK!


The bear is stalking (hunting) you along a trail and then attacks. Or, the bear attacks you at night. This type of attack is very RARE.

  • Try to escape into a building, car or up a tree.
  • If you cannot escape, do not play dead.
  • Use your bear spray and FIGHT BACK.

    Intimidate that bear: shout; hit it with a branch or rock, do whatever it takes to let the bear know you are not easy prey. This kind of attack is very rare, but it is serious because it usually means the bear is looking for food and preying on you.

    The take away lesson here is you better have some bleeping bear spray.

  • This is a wildly unrealistic, over-dramatized depiction of a human-bear encounter. The advice given does not seem to be based on any cited evidence. The answer adds to the incorrect perception that bears present a significant risk of harm to humans. The reality is that humans have greatly harmed bears.

This depends quite a bit on the type of bear. An American black bear doesn't see a human as prey. Even a grizzly will normally only attack a human if it's surprised, threatened, or protecting its young. A polar bear may see a human as prey.

So the initial, very general meta-answer to your question is that if you're going to observe or interact with wildlife, you should learn all about that wildlife. Different species are different. Their behaviors can be totally different, and you can misinterpret their behaviors if you don't know enough. Observing wildlife in the wild is a wonderful way to experience the natural world, but it's sort of similar to looking through a telescope -- you'll get the most out of the experience if you understand what you're looking at and what to look for.

Since you don't say what species you're talking about, I'll assume for the remainder of this question that you're talking about a black bear. This is a species that people in the most populated areas of North America have a considerable chance of coming into contact with. Re black bears, you might want to keep in mind that they're often not even that big. A small one can be about the size of a German shepherd.

Black bears differ in how much they're habituated to humans. In a small number of very specific areas, such as Yosemite Valley, you get a large number of bears that are used to people and frequently get human food. These bears may be relatively unafraid of humans. They may raid an unattended backpack or an improperly secured garbage can. These animals have been harmed by humans, because they have acquired dysfunctional and unnaturally distorted habits. If you see one of these animals, your goal should be to avoid further harming it. Hopefully you haven't already contributed to its harm by leaving your food unattended.

Outside of these very specific areas, black bears are typically not habituated to humans, so they're afraid of you. As soon as the bear sees you, it's going to run away.

  • I upvoted this answer, but I'd be happier with it if it didn't leave the impression in the last sentence that one can count on a black bear running away. Between the bear and you seeing each other, and the bear satisfying herself that you are not a source of food, there are opportunities for the neophyte to do something stupid.
