Big Bear Lake is beautiful, but the bears in Big Bear are the real reason people stay up at night—sometimes literally. You’re sitting on a deck in Moonridge, the air smells like Jeffrey pine and woodsmoke, and suddenly a 300-pound shadow trots past your trash can. It’s a thrill. It’s also a massive responsibility that a lot of weekend warriors completely blow.
Most people assume these animals are aggressive predators waiting in the bushes. Honestly? That’s just not the case. They’re basically giant, furry opportunists with noses that can pick up a discarded Snickers wrapper from a mile away.
The Reality of Bears in Big Bear: They Aren't Who You Think
First things first: there are no Grizzly bears in Big Bear. None. Zip. If you see a big brown animal, it’s a Black Bear. I know, the name is confusing because they can actually be blonde, cinnamon, or chocolate brown. But the California Grizzly? That’s been extinct since the 1920s. We just kept the image on the state flag.
Black bears (Ursus americanus) are the only species you’ll encounter in the San Bernardino Mountains. They aren't naturally mean. They’re smart. Scary smart. They’ve learned that humans are messy, and messiness equals an easy 5,000-calorie dinner without having to dig for grubs or hunt for berries.
Why the "Garbage Bear" Label is Dangerous
When a bear gets too used to people, biologists call it "habituation." It sounds clinical. It’s actually a death sentence. A bear that loses its fear of humans will eventually break into a house or a car. Once they start doing that, the California Department of Fish and Wildlife often has no choice but to euthanize them.
The local saying is "a fed bear is a dead bear." It’s a cliché because it’s true. People think they’re being kind by tossing a piece of bread or leaving a cooler out. You’re not being kind. You’re killing it.
The bear population here is thriving, though. Estimates suggest there are hundreds of them roaming the San Bernardino National Forest. They love the combination of dense timber and the proximity to the lake, which provides hydration and lush vegetation.

The Anatomy of a Big Bear Encounter
So, you’re hiking the Castle Rock Trail and you see one. What now?
Most people’s instinct is to run. Do not do that. Seriously. Bears can hit 35 miles per hour. You can't. If you run, you look like prey. Instead, you need to stand your ground. Talk to it. Not in a "hey buddy" way, but in a firm, loud voice. "Whoa, bear! Get out of here, bear!"
Make yourself huge. Raise your arms. If you have a jacket, open it up. Most of the time, the bear will look at you, realize you’re a loud, annoying human, and huff as it wanders off. That "huffing" sound is a sign of nervousness, by the way. They aren't growling at you like in the movies; they’re telling you they’re uncomfortable.
Car Break-ins: It's Not Just About Food
Bears in Big Bear have figured out how to open car doors. I’m not joking. If you leave your car doors unlocked, they will pull the handle. If the door is locked but they smell something good inside, they might just peel the window frame back.
It’s not just "food" they’re after. They love:
- Lip balm
- Sunscreen
- Scented air fresheners
- Empty soda cans
- Gum wrappers
- Even car seats where a toddler spilled some juice three weeks ago
If it has a scent, it’s a target. Local residents will tell you stories of bears getting stuck inside SUVs and absolutely shredding the interior because they panicked. It’s a total loss for the car owner and a traumatic event for the bear.

Seasonal Cycles and What to Expect
Bears don’t actually sleep all winter. Not fully. In Big Bear, they enter a state called torpor. It’s a deep sleep, but they can wake up if the weather gets weirdly warm or if they get disturbed.
During the fall—roughly September through November—they enter "hyperphagia." This is their bulking phase. They need to eat around 20,000 calories a day to survive the winter. This is when the bears in Big Bear are most active and most likely to wander into residential neighborhoods. They are desperate. They are hungry. And they are everywhere.
In the spring, they emerge with cubs. If you see a cub, stay away. Mama bears aren't looking for a fight, but they will absolutely end one if they think you’re a threat to their young. If you find yourself between a mother and her cub, you are in the most dangerous spot in the woods. Back away slowly and give them a wide berth.
Living with the Locals
If you’re renting a cabin or staying at a lodge, you’ve got to use the "Bear Box." These are heavy steel containers designed to keep wildlife out of the trash. If you leave your trash bag next to the box because you’re too lazy to open the heavy lid, you’ve just invited the whole neighborhood to a buffet.
Why the Bear Population is Changing
Climate change is shifting things. Shorter winters mean bears are staying active longer. Also, the massive influx of tourists to Big Bear Lake since 2020 has put more pressure on the ecosystem. More people means more trash. More trash means more bears in backyards.
Biologists like those at the Big Bear Alpine Zoo (which is a rehabilitation facility, not a traditional zoo) work hard to educate the public. The bears there, like Holly and Lucky, are permanent residents because they became too habituated to humans or were orphaned. They serve as ambassadors. If you want to see a bear safely, go there. Don't go looking for them in the woods with a selfie stick.

Your Safety Checklist for Big Bear
Let’s be real. The odds of a bear attacking you are incredibly low. You’re more likely to get hurt falling off a mountain bike or slipping on ice in the Village. But, respect is mandatory.
- Lock your windows. Ground-floor windows in cabins are basically doors for a bear.
- Ditch the bird feeders. Seeds are high-calorie snacks that attract bears directly to your porch.
- Carry bear spray. If you’re hiking deep into the forest, it’s a good "just in case" tool. Know how to use it before you need it.
- Keep dogs on a leash. A loose dog will bark at a bear, get scared, and then run back to you with the bear chasing it. Not a good scenario.
- Clean the grill. A greasy BBQ lid is a siren song for a hungry 400-pound male.
Misconceptions About "Aggression"
People often report "aggressive" bears that are actually just curious or hungry. If a bear stands on its hind legs, it’s not about to charge. It’s trying to get a better look and smell. It’s curious. It’s trying to figure out what you are.
A truly aggressive bear will put its ears back, lower its head, and make a popping sound with its teeth. If that happens, you’ve messed up. Back away. Don't scream. Just leave.
Actionable Steps for Your Visit
To truly enjoy the wildlife without causing harm, you need to change your mindset. You are a guest in their living room.
- Invest in a "Bear Bag" or Cannister if you are backcountry camping. Don't hang food from trees; bears here have learned how to parkour their way to those bags.
- Report sightings to the locals. If a bear is acting strangely or getting too close to houses, let the local rangers know. They track these movements to see if a specific bear is becoming a "problem" individual.
- Use your car's alarm. If you see a bear approaching your vehicle, hit the panic button on your key fob. The sudden, loud, artificial noise is often enough to spook them.
- Talk to your neighbors. If you're in a rental, ask if there’s been recent bear activity. Knowledge is your best defense.
The bears in Big Bear are part of what makes the mountain special. Seeing one from a distance is a magical experience that reminds you how wild California still is. Just make sure your encounter stays a "cool story" rather than a cautionary tale for the local news. Keep your food locked up, your eyes open, and your distance respectable. The bears will thank you by staying alive and wild.
