If you encounter a brown bear, your response depends on whether the bear is aware of you, how close it is, and whether it’s acting defensively or treating you as prey. The single most important rule: stay calm, never run, and keep at least 100 yards between you and the bear whenever possible. Most brown bear encounters end without injury if you read the situation correctly and respond accordingly.
Make Sure It’s a Brown Bear
Your response to a bear encounter differs by species, so correct identification matters. Brown bears (including grizzlies) have a distinctive muscular hump on their shoulders, short rounded ears, and long, slightly curved front claws measuring 2 to 4 inches. Black bears lack the shoulder hump, have taller oval-shaped ears that look prominent on their head, and shorter claws under 2 inches. Color alone is unreliable since both species range from blonde to nearly black. Focus on the shoulder hump and ear shape first.
If You See a Bear at a Distance
The National Park Service prohibits approaching within 100 yards (about the length of a football field) of bears on most public lands. If you spot a brown bear from farther away, quietly change your route to give it space. Move upwind if possible so the bear can catch your scent and identify you as human, which typically causes it to move off on its own. If you’re on a trail with no alternate route, wait for the bear to leave the area before continuing.
Never stop your car near a roadside bear. If you want to watch, drive at least 100 yards past the animal and pull over safely.
If a Brown Bear Sees You Up Close
When you suddenly find yourself within 100 yards and the bear knows you’re there, slow everything down. Talk in a calm, low voice so the bear can identify you as human. Avoid direct eye contact, which bears can read as a threat. Stand your ground, make yourself appear large by standing tall, and slowly back away at an angle. Do not turn your back, and absolutely do not run. Brown bears can sprint at 35 miles per hour. You cannot outrun one, and running triggers a chase instinct.
If the bear stands on its hind legs, it’s usually trying to get a better look and smell. This is curiosity, not aggression.
Reading a Bear’s Body Language
A brown bear that feels surprised or threatened will display defensive behaviors. It may yawn, clack its teeth, huff, and pound its front paws on the ground. These are warning signs telling you to back off. A bear that bluff charges will hold its head and ears up and forward, puff itself up to look bigger, and bound toward you in big leaps before stopping short or veering to one side. Bears often retreat after a bluff charge or vocalize loudly. Hold your ground during a bluff charge. Running confirms you as something worth chasing.
An aggressive charge looks different. The bear drops its head low with ears pinned back and comes at you like a freight train, with no hesitation or veering. This bear intends to make contact.
A predatory bear behaves differently from both of these. It will follow you quietly, circle around you, or stalk you with focused attention. It isn’t reacting out of surprise or defending cubs or food. It has identified you as potential prey. This distinction determines everything about your response.
What to Do If a Brown Bear Attacks
For a defensive attack (the bear was surprised, is protecting cubs, or guarding food), play dead. Drop face-down on the ground, spread your legs wide to make it harder for the bear to flip you over, and lace your fingers behind your neck to protect it. Keep your backpack on for added protection. Stay in this position and do not move until you are certain the bear has left the area. If you fight back against a defensive brown bear, you typically escalate the encounter. The bear wants to neutralize a perceived threat, and once it believes you’re no longer dangerous, it will usually leave.
For a predatory attack, where a bear has been stalking you, following you, or approaches you in your tent at night, playing dead will not work. Fight back with everything available. Aim for the bear’s face, eyes, and nose. Use rocks, sticks, trekking poles, or your fists. Make noise. A predatory bear will not stop because you appear passive.
How to Use Bear Spray
Bear spray is your best tool in brown bear country. EPA-registered sprays shoot a minimum of 25 feet and last at least 6 seconds, giving you enough coverage for a bear that zigzags, circles, or charges more than once. A study analyzing 66 field incidents found that bear spray stopped undesirable brown bear behavior in 94% of cases.
Carry the spray in a hip or chest holster where you can grab it in under two seconds. Do not bury it in your pack. When a bear charges, remove the safety clip, aim slightly downward toward the ground in front of the bear (the spray creates a cloud), and begin spraying when the bear is within 25 to 30 feet. Use short bursts if the bear is still approaching, and empty the canister if necessary. After spraying, back away from the area immediately since the spray cloud dissipates and the bear may return.
Practice drawing and aiming with an inert training canister before your trip. In a real charge, you will have only a few seconds to react.
Preventing Encounters in the First Place
Most brown bear encounters happen because a bear didn’t know you were coming. Make noise on the trail, especially around blind corners, dense brush, and near streams where running water masks sound. Travel in groups of three or more. Bear attacks on groups of four or more are extremely rare.
Food management is equally critical. In brown bear habitat, store all food, trash, and scented items (toothpaste, sunscreen, cooking clothes) in bear-resistant containers approved by the Interagency Grizzly Bear Committee. These containers are tested against live captive grizzlies and must resist a bear’s efforts to open them. Coolers on the IGBC-approved list require a padlock or carabiner to qualify as bear-resistant. An unlocked cooler is not considered bear-proof.
If you don’t have a certified container, store food in a locked hard-sided vehicle, or hang it at least 10 feet off the ground and 4 feet away from any tree trunk or branch a bear could climb. Cook and eat at least 200 feet from where you sleep, and change out of clothes you cooked in before getting into your tent.
Recognizing Brown Bear Signs on the Trail
Knowing you’re in active bear territory lets you increase your alertness and noise level before an encounter happens. Brown bear tracks are large with toes squeezed close together, showing little spacing, and the toes do not form an arc the way black bear prints do. Scat varies by season: berry-filled droppings in late summer, grass-heavy piles in spring, and chunks of fish or animal hair during salmon runs. Digging sites where the ground has been torn up for roots or ground squirrels are a strong indicator of recent grizzly activity, since their long claws make them far more prolific diggers than black bears.
Fresh tracks, warm scat, or a strong animal smell in the area mean a bear could be very close. Increase your noise, group up tightly, and have your bear spray in hand.
After a Bear Attack
If you or someone in your group is injured, call 911 or activate an emergency beacon immediately. Control bleeding by applying continuous pressure for 5 to 10 minutes. Wash wounds with soap and a large volume of water for at least 5 minutes, scrubbing enough to make the wound bleed slightly again to help flush out debris. Bear bites carry a high risk of infection. Even wounds that look manageable need professional medical evaluation as soon as possible.
