Short answer: yes. You need bear spray in Glacier National Park. But here’s the part nobody tells you: carrying it isn’t enough. Bear spray won’t help you if you have it and don’t know how to use it.
I worked as a server in Glacier (here’s how I got my seasonal job), and I can’t tell you how many times a guest told me some wild thing they did with their bear spray. Or how many people told me they had it but had no idea how to use it.
Stories from my tables
One table told me they saw a bear while walking the Highline Trail, so they ran. Running is the number one thing you’re not supposed to do. Then they asked me if they should keep the safety clip off while hiking so they’d be ready. No. That’s how you bear spray yourself.
And it happens all the time. Some people treat it like mosquito spray and spray it on themselves. Please do not do this. It hurts a lot. Bear spray is basically a really strong pepper spray, and it’s meant to go in a charging bear’s face, not on you, your tent or your gear.
No judgment here, though. I didn’t know how to use it for the longest time. I used to live in Yellowstone, which is serious bear territory, and I kind of knew how to use it, but not really. Once I got to Glacier and saw how many bears were around and heard about the bear incidents, I knew I had to actually learn. So I went on YouTube and watched multiple videos until I felt confident.
Why Glacier is serious bear country
According to the National Park Service, Glacier provides habitat for nearly one thousand bears, with recent estimates around 300 grizzlies and 600 black bears. Grizzlies are the main concern, and Glacier has a lot of them.
I’ve seen a lot of bears in Glacier, especially on the east side, where most of the best hiking is (like the Many Glacier hikes). Turns out bears like the good views too.
But don’t be nervous. Just be safe. Bears typically want nothing to do with humans. Most attacks happen because a bear got surprised or spooked. I’ve seen quite a few grizzlies while hiking. I just make sure they know I’m around by talking and saying “hey bear,” and they don’t even look up. They just keep doing what they’re doing.
Be bear aware on the trail
- Make noise. Talk, call out “hey bear,” and clap, especially around blind corners, streams and thick brush. Skip the bear bells. A lot of people call them dinner bells. They’re not proven to work, and the NPS says they aren’t adequate. Your voice works way better.
- Hike in groups when you can. The NPS says there have been no reported attacks on groups of four or more in Glacier.
- Hiking solo? Be extra aware. When I hike alone, I talk out loud or play an audiobook on speaker to make noise. I turn the volume down when people pass by, but to me it does the same job as talking. Still call out at blind corners.
- Don’t run on trails. Trail running is how people surprise bears.
- Keep your distance. This isn’t a zoo. I see people getting way too close to bears, like they’re at a zoo. These are wild animals that could attack at any moment. Glacier requires you to stay at least 100 yards away, about the length of a football field. If the bear changes what it’s doing because of you, you’re too close. Use binoculars or zoom in with your camera instead.
- Sign up for Glacier’s text alerts. Text GNPTRAILS to 333111 and the park will text you trail postings and closures, like when a trail closes because of bear activity or gets posted for a lot of bear activity. It’s free, and it’s one of the best ways to know before you go. You can also text GNPROADS for road updates and GNPCGS for campground updates. (Source: NPS road, trail and campground status)
- Keep your spray in your hand or on your hip. I’ve never had to use mine or even unclip the safety. But having it in my hand and accessible is a huge safety measure for me, and it helps with my anxiety.
How to actually use bear spray
Carry it on your hip or chest, never buried in your backpack. Keep the safety clip on until you need it.
Don’t spray a bear just because you see one. Only use bear spray if the bear is showing aggressive behavior and looks like it’s about to charge you. Signs of an agitated bear include huffing, clacking its teeth, swaying its head, a lowered head or ears laid back. If a bear is minding its own business, you should not be bear spraying it. Give it space, back away and let it be.
If a bear is acting aggressive and charges or gets too close:
- Don’t run. Stay calm, talk to the bear quietly and back away slowly if you can.
- Grab your spray with your dominant hand.
- Pull off the safety clip.
- Hold it with both hands.
- Aim at the bear’s face, slightly downward, so the spray makes a cloud between you and the bear.
- Spray a short burst of 2 to 3 seconds.
- If the bear keeps coming, spray again.
- Once the bear leaves, put the safety clip back on and calmly leave the area. Don’t run.
A few more things to know:
- Most cans only spray for a few seconds and reach about 20 to 40 feet, so don’t waste it.
- Watch the wind. Wind in your face can blow the spray back at you.
- Everyone in your group should carry their own can.
- Never test-spray your real can. It wastes spray, and some rental shops will charge you for it.
- Never leave it in a hot car. Temperatures over 120°F can make the can explode.
- Headed to Waterton in Canada? Canadian customs only allows bear spray with “USEPA” on the label.
Watch this before you go
Reading steps is one thing. Seeing it done is another. This video from Montana Fish, Wildlife & Parks walks through it:
- Using Bear Spray, Glacier National Park’s own video (about 2.5 minutes)
- Glacier National Park Bear Safety page: safe distances, what to do in an encounter, and the park’s bear safety video
- BearWise bear spray guide: a great step-by-step and FAQ
If you’re nervous, practice with a fake can
You can buy an inert practice canister. It sprays like the real thing but has no pepper in it. I’ve done this before and it’s so nice to practice with. Practice pulling it out of the holster, popping the safety and aiming, so it’s automatic if you ever need it.
Here’s the practice canister I recommend.
What to do if bear spray gets on you
Accidents happen, especially with wind. If you get sprayed:
- Get to fresh air and out of the spray cloud.
- Don’t rub your eyes or face. Rubbing makes it worse.
- Flush your eyes with lots of clean, cool water. Take out contact lenses.
- Wash skin with soap and water. Bear spray is oil-based, so water alone won’t cut it. Dish soap works well. Wipes help if you’re on the trail.
- Take off and wash any clothes that got hit.
- Give it time. It’s painful, but effects usually wear off in about 45 minutes and don’t cause permanent damage.
- Get medical help if you have trouble breathing or it isn’t improving. You can also call Poison Control at 1-800-222-1222.
Where to buy bear spray cheap
- Walmart: around $35 to $45, the cheapest option I’ve found.
- In and around Glacier: usually $45 to $50 at visitor centers, gift shops and outdoor stores.
Make sure the can says “bear spray” or “bear deterrent” and has an EPA registration number. Regular pepper spray isn’t the same thing.

Flying home? You can’t take it on the plane
Bear spray isn’t allowed on airplanes, in carry-on or checked bags. If you bought a can, leave it at the lodge you stayed at. They usually let employees use it or keep it, so it goes to someone who needs it. Or just rent and skip the problem. Still deciding where to stay? Here’s my guide to where to stay in Glacier.
