Bear Safety in National Parks: Things You Should Know

05 15 2025

Over 330 million people visit U.S. national parks each year, seeking breathtaking landscapes, a peaceful escape from everyday life, and the chance to witness some of nature’s most incredible wildlife up close. But the same wild beauty that draws millions in also comes with very real risks. Around 1,000 people vanish in national parks annually, emphasizing the importance of proper preparation and caution while exploring these vast, untamed wilderness areas. It is important to remember that these parks are living ecosystems, where powerful animals roam freely and conditions can shift in an instant. Respecting the land and its inhabitants isn’t just good practice, but it’s key to your survival.



So, how can you enjoy the beauty of the outdoors while keeping yourself protected? It all starts with knowledge and preparation. Whether you're hiking solo, camping with friends, or road-tripping through bear country, knowing how to protect yourself from potential dangers, especially encounters with wildlife, is crucial. Understanding the risks and equipping yourself with the right tools can help ensure your experience in the wild is both safe and unforgettable.



Among the most essential safety tools for any outdoor adventurer, bear spray is a powerful, non-lethal deterrent that could make all the difference in your trip to a national park. This guide will inform you on what you need to know before your next trip in a national park.



Bear Encounters in National Parks

National Parks are more than just breathtaking landscapes. They’re home to some of the most incredible wildlife. Imagine the way the morning mist clings to the trees, the distant sound of a grizzly bear’s growl, and the quiet thrill of what lies just around the corner. These moments of wonder make every visit to a park feel like stepping into another world. But with that beauty comes responsibility.



From the dense forests of the Pacific Northwest to the rugged terrain of the Rockies, U.S. National Parks are filled with wildlife, including black bears and grizzly bears. The reality of encountering one of these bears is high. It's not a matter of if, but when. Whether you’re hiking a well-traveled path or setting up camp near a quiet river, bears are part of the environment you’re stepping into. Respecting the presence of bears, staying alert, and being properly prepared is key to ensuring both your safety and the well-being of these incredible animals.



There are currently 63 National Parks in the United States. If you're exploring Yellowstone or Glacier National Park, it's crucial to be prepared when venturing into bear country. Black bears and grizzly bears have notable differences in both appearance and behavior, and understanding these differences can help you respond appropriately in an encounter. Before you embark on your adventure, research to know how to spot the difference between a black bear and a grizzly bear. Still, one tool remains effective against both: bear spray. It’s your strongest line of defense and something no adventurer should hit the trail without.

Understand Bear Behaviors

What’s the difference between black bears and grizzly bears?

If you’re venturing into bear country, being able to tell the difference between black bears and grizzlies is an important part of staying safe. Although they may appear similar at a glance, their size, physical features, and typical reactions to threats can differ greatly. The U.S. National Park Service offers guidance on identifying bear species, and understanding these distinctions can help you respond more appropriately during an encounter.



Black bears are usually smaller, with straight facial profiles and no shoulder hump. Grizzlies (also known as brown bears) are larger, have a distinct shoulder hump, and feature a concave facial profile. In terms of behavior, grizzlies are more likely to react aggressively when startled, while black bears tend to flee from perceived threats.

Get Bear Smart

When are bears awake?

Bear activity increases during the spring, summer, and early fall, with each season bringing different reasons for bears to be out and about. In the spring, bears are starting to wake up from hibernation, so they are hungry and ready to eat. Next, the summer is all about calories. As the weather warms up, bears become more active and roam wider ranges to find high-energy foods. They’ll forage for berries, dig for insects, and even fish for salmon in rivers. By late summer into early fall, their feeding reaches a peak. Bears enter a phase called hyperphagia, where they eat constantly to fatten up for the next winter (bear.org). During this time, they can gain several pounds a day, so they’re especially focused on finding food and less likely to leave an easy meal behind.



Bears tend to be most active at dawn and dusk, when it’s cooler and quieter. These “crepuscular” hours are prime time for movement, especially in areas where human activity is low. If you’re hiking or camping during these times, it’s smart to stay alert and make your presence known by talking, clapping, or using bear bells.

Bear Spray In National Parks

Yes, in most national parks bear spray is legal and often recommended. In places like Yellowstone and Glacier National Parks, where encounters with bears and mountain lions are more common, park officials actively encourage visitors to carry bear spray. It's considered one of the most effective tools for deterring aggressive wildlife, with over 90% success in stopping bear attacks when used properly.



Bear spray is legal to carry in most U.S. National Parks, but specific regulations may vary by location. It’s crucial to understand the rules before your trip. In parks like Yellowstone and Glacier National Parks, park officials strongly recommend carrying bear spray as a key safety measure. However, other parks, like Yosemite, have stricter rules that prohibit bear spray. It is stated that bear spray in Yosemite is considered a weapon under federal law. Before visiting a National Park, always check on the park’s website to learn about their bear spray regulations. For those venturing into parks where bear spray is restricted, alternative deterrents are recommended. Noise-making devices like bear bells or bear horns are effective tools that can help reduce the likelihood of a close encounter with a bear. Since rules vary from park to park, it's important to check each park’s specific regulations before your visit. Being informed could mean the difference between a close call and a safe, unforgettable adventure.

Why Do Bears Approach Humans?

Bears usually want nothing to do with people, but there are a few reasons they might approach humans. The biggest reason? Food. Bears have an insanely good sense of smell. They can sniff out a granola bar from over a mile away. If you’re carrying snacks in your backpack, left some crumbs in your tent, or forgot to secure your trash back at your campsite, there’s a good chance a hungry bear will come looking. Curiosity is another common reason. This especially applies to younger bears, who are still learning about their environment. A young bear might wander closer just to see what you are and what you’re doing. They’re not necessarily being aggressive, instead, they’re just curious. On the contrary, you could be hiking quietly around a bend or through thick brush and surprise a bear that wasn’t expecting you. In these cases, the bear might feel threatened and act defensively. This does not mean it wants to attack, but typically it’s scared or startled. That’s why making noise while hiking is so important.



Pro tip: Clip a bear bell on your backpack or belt loop, so you are constantly making noise and alterting any nearby wildlife of your presence.

What to Do If You Encounter a Bear

Spotting a bear on the trail can be heart-pounding, but knowing how to respond can make all the difference. Whether you're hiking in Yellowstone, Glacier, or any area with bear activity, staying calm and carrying bear spray in national parks is key to protecting yourself and the bear.



Here’s a step-by-step guide for staying safe during a bear encounter:

1. Stay Calm and Don’t Run

Your gut reaction might be to bolt—but don’t. Running can trigger a bear’s instinct to chase, and they can outrun humans even on rough terrain. Instead, take a deep breath, stand your ground, and assess the situation.

2. Speak Calmly and Back Away Slowly

Let the bear know you’re human and not prey. Speak in a low, calm tone—don’t shout—and slowly begin to back away without turning your back. Avoid direct eye contact, which the bear could interpret as a challenge. The goal is to give the bear space to leave on its own.

3. Try to Identify the Bear Species

If you can do it safely, identifying whether you're facing a grizzly bear or a black bear may influence your next move:

  • Grizzlies are more likely to defend themselves aggressively when surprised.
  • Black bears are more likely to retreat if given space.

This knowledge can help guide your behavior if the situation escalates.

4. Hold Your Ground if the Bear Approaches

If the bear moves toward you, don’t run or scream. Stay calm, raise your arms slowly to appear larger, and continue speaking in a firm voice. In many cases, bears approach out of curiosity, not aggression.

5. Use Bear Spray If the Bear Gets Too Close

This is where bear spray becomes essential. If the bear keeps coming and gets within range (about 20–30 feet), spray in short bursts, aiming low so the fog rises into the bear’s face. The intense formula causes burning and disorientation, giving you time to retreat safely.



Bear spray tips:

  • Practice before your trip using a training canister.
  • Always carry it in a holster—not buried in your backpack.
  • Check expiration dates and keep it handy, especially when hiking in known bear country.

National Park Bear Safety Protocols

Every park has its own bear protocols. Some may require bear canisters, others may restrict access to high bear-activity zones. What applies to Yellowstone might not apply in Glacier or Denali. Check regulations specific to your destination.



Before hitting the trail, check in with park rangers. They'll know where bear sightings have occurred and can give up-to-date advice. Pay attention to trailhead signs, which often warn of recent bear activity and offer essential safety reminders.



National parks offer breathtaking landscapes and a rare chance to connect with nature. Whether you're hiking through towering pines, kayaking along a crystal-clear river, or simply taking in a sunset, the beauty of these wild places is undeniable. However, with the privilege of exploring these natural wonders comes the responsibility of respecting the wildlife that calls them home. Bears, mountain lions, and other animals are part of the national park, and it’s important to remember you’re a guest in their environment.



Preparing for the possibility of an encounter with a bear is essential for your safety and theirs. Carrying bear spray, understanding bear behavior, and being mindful of when and where animals are most active are all crucial steps in ensuring a safe and respectful visit.



Knowing how to handle a grizzly bear or black bear encounter doesn’t just protect you, but it helps protect the bear, too. Calm, confident reactions can de-escalate a tense situation and prevent it from becoming more dangerous.



Before you go, always check the specific park’s rules and guidelines. Regulations vary from park to park, and staying informed will help you enjoy your adventure safely. With proper preparation and respect for nature, your time in a national park can be both thrilling and safe, offering memories you’ll cherish for a lifetime.



Happy exploring! Remember to keep your distance and stay bear-aware!
