Everything You Need to Know About Bear Canisters for Backpacking
Bear canisters are essential tools for safely storing food while backpacking, especially in areas inhabited by bears. They are designed to prevent bears from accessing your food, thereby keeping both you and the bears safe. By ensuring that bears do not associate humans with food, bear canisters help maintain the natural behavior of wildlife and protect hikers.

Importance of Bear Canisters
Protection
Bear canisters play a critical role in protecting bears from becoming dependent on human food. When bears start associating humans with easy food sources, they can become bold and aggressive, which often leads to dangerous encounters. Sadly, such bears might need to be euthanized for public safety. By using bear canisters, backpackers can prevent this scenario, helping to preserve wildlife.
Safety
Bear canisters not only protect bears but also ensure the safety of backpackers. A bear that has access to human food can become a persistent threat. Keeping food securely stored reduces the likelihood of bear encounters, making your outdoor experience safer and more enjoyable.
Key Points on Bear Canister Usage
Proper Use
Using a bear canister is straightforward. Place all food, scented items, and trash inside the canister and keep it securely locked. This simple practice is highly effective in preventing bears from getting to your supplies.
Legal Requirement
In many bear-inhabited areas, using a bear canister is not just a recommendation but a legal requirement. This regulation helps manage human-bear interactions and promotes the safety of both parties.
Additional Benefit
A fun and practical bonus: bear canisters can double as camp chairs! Their sturdy construction allows you to use them as a seat around the campsite.

Bear Canister Details
Definition
Bear canisters are hard-sided, bear-proof containers designed to store food, scented consumables, and trash. They are an essential piece of gear for anyone backpacking in bear country.
Effectiveness
Bear canisters are highly effective at preventing bears from accessing food. While bears can still smell the food inside, they cannot access it, which discourages them from seeking out human campsites.
Smell Management
Even though bear canisters prevent bears from accessing food, they can still smell it. Therefore, it is crucial to store canisters away from your tent—typically 100-300 feet downwind.
Where Bear Canisters Are Required
Bear canisters are recommended in all bear habitats and are mandatory in many specific parks and forests, including:
- Appalachian Trail
- Big Bend
- Canyonlands
- Denali
- Glacier
- Grand Teton
- Inyo
- Lassen Volcanic
- Maroon Bells
- North Cascades
- Olympic
- Rocky Mountain
- Yosemite
Certification
Bear canisters should be certified by the IGBC (International Grizzly Bear Committee) and SIBBG (Sierra Interagency Black Bear Group). These certifications ensure the canisters meet rigorous standards for bear resistance.
Bear Canister Size
A good rule of thumb is to allocate 100 cubic inches (1.6L) per day for food and toiletries. Efficient packing is crucial—remove excess packaging, organize food by day, and pack strategically to maximize space.
Carrying Bear Canisters
For optimal weight distribution, place the canister in the center of your backpack. Alternatives include securing it under the pack brain, on top, or at the bottom, depending on your pack’s design.
Using Bear Canisters in Camp
- Security: Keep the canister locked except when accessing food.
- Placement: Store the canister 100-300 feet downwind from your tent, away from cliffs and water sources.
- Bear Alarm: Placing noisy items on top of the canister can alert you if a bear investigates.

Bear Canister Alternatives
While lightweight bear-resistant bags like the Ursack Major & AllMitey are available, they are not approved in some areas that require hard-sided containers. Always check local regulations before using these alternatives.
Renting Bear Canisters
If you prefer not to purchase a bear canister, consider renting one. Many local outdoor shops, national parks, and retail chains like REI offer rental services, which can be a cost-effective solution for occasional backpackers.
By adhering to these guidelines and choosing the right bear canister for your needs, you can enjoy your backpacking adventure while protecting both yourself and the bears. Happy hiking!
